The SiS 6326 was a graphics processing unit (GPU) manufactured by Silicon Integrated Systems. It was introduced in June 1997 and became available to the consumer market in the end of that year. Although its performance was low compared to the GPUs of its age, eventually it became very successful, specially integrated in many motherboards designed to the corporate market, where the low cost is prioritized over 3D performance. SiS shipped over seven million units of the SiS 6326 in 1998.

Architecture

The SiS was available as a discrete card, with an AGP 2x or PCI bus, and as an integrated GPU. It had a 64-bit 2D/3D graphics accelerator [with most cards running at 75 MHz and later revisions running at 90 MHz], a DVD decoder and a TV decoder. It was available with 4 MB or 8 MB of memory.

Performance

Since the model aimed for low cost over high performance, its capabilities were low compared to contemporary products. According to a test conducted by Tom's Hardware on January 21, 1998, it possessed roughly a third of the performance of an NVidia RIVA 128 or 40% less than an ATI Rage Pro in terms of frames per second in Direct3D benchmarks, and simply could not play Quake 2 due to its lack of OpenGL support. Yet the same article says that even the "slow and unknown graphic chip" could still produce "quite nice image quality".

A beta driver codenamed Java was released as late as 1999, being the only version with an OpenGL ICD included, which finally allowed it to run some OpenGL applications such as GLQuake, Quake 2 and GLexcess. it still crashes in Quake 3 though, due to its incomplete 3D features.

The SiS 6326 was even capable of running relatively newer 3D applications such as 3DMark2001/2001, with no significant image flaws to be found despite its abysmal speed.

Linux support

There is little support for Linux aside from the drivers developed independently by Thomas Winischhofer. Since the driver does not support OpenGL, not even the Windows one provided by SiS, it only allows for 2D acceleration. There is also an experimental FrameBuffer driver developed by Sergio Costas, currently unsupported, available only for 2.4 kernels and without any kind of hardware acceleration. This driver was not ported to 2.6 because the native VesaFB driver available offered the same capabilities.

Variants and immediate successors

In 1998, DVD/Macro-Vision and then AGP variants of the SiS 6326 were released. Later that year, northbridge chipsets with integrated GPUs were released: SiS 530 for Socket 7, and SiS 620 for socket 370, both based in a cut down version of the SiS 6326, named SiS 6306 operating at 40 MHz. It was in April 1999 that the SiS 6326 was made officially obsolete by the SiS 300.

The SIS Building, also called the MI6 Building, at Vauxhall Cross houses the headquarters of the Secret Intelligence Service (SIS), also known as Military Intelligence, Section 6 (MI6), the United Kingdom's foreign intelligence agency. It is located at 85 Albert Embankment in Vauxhall, London, on the bank of the River Thames beside Vauxhall Bridge. The building has been the headquarters of the SIS since 1994.

History

Background

Previously based at 54 Broadway, the SIS relocated to Century House, a 22-storey office block on Westminster Bridge Road, Lambeth, near Lambeth North and Waterloo stations, in 1964. Its location at Century House was classified information, though The Daily Telegraph reported that it was "London's worst-kept secret, known only to every taxi driver, tourist guide and KGB agent". Century House was described as "irredeemably insecure" in a 1985 National Audit Office (NAO) report with security concerns raised in a survey; the modernist building was made largely of glass, and had a petrol station at its base. Security concerns combined with the remaining short leasehold and cost of modernising the building were important factors in moving to a new headquarters.

Design and construction

The site on which the SIS building stands had been the location of the Vauxhall Pleasure Gardens in the 19th century. Several industrial buildings were subsequently built on the site after the demolition of the pleasure gardens in the 1850s, including a glass factory, a vinegar works and a gin distillery. Archeological excavation of the site during building found the remains of 17th-century glass kilns, as well as barge houses and an inn called The Vine. Evidence was also found for a river wall on the site.

In 1983 the site was bought by property developers Regalian Properties. A competition to develop the site was won by architect Terry Farrell, with an urban village as Farrell's original proposal. A scheme of office blocks was subsequently developed for the site, with a government agency as their occupier. The building had been sold for £130 million in 1989, with construction planned to take three years, built by John Laing. SIS ultimately became the occupiers of the building. Farrell's design for the building was influenced by 1930s industrial modernist architecture such as Bankside and Battersea Power Stations and Mayan and Aztec religious temples.

Regalian approached the government in 1987 to assess their interest in the proposed building. In 1988 Prime Minister Margaret Thatcher approved the purchase of the new building for the SIS. The NAO put the final cost at £135.05 million for site purchase and the basic building or £152.6 million including the service's special requirements.

The site is rumoured to include a tunnel under the Thames from the building to Whitehall.

The numerous layers over which the building is laid out create 60 separate roof areas. 25 different types of glass were used in the building, with 130,000 square feet (12,000 m²) of glass and aluminium used in the building's construction. The windows in the SIS building are triple glazed for security purposes. Due to the sensitive nature of MI6's work, large parts of the building are below street level, with numerous underground corridors serving the building. Amenities for staff include a sports hall, gymnasium, aerobics studio, a squash court and a restaurant. The building also features two moats for protection.

The building was completed in April 1994 and officially opened by Queen Elizabeth II accompanied by Prince Philip, Duke of Edinburgh, on 14 July 1994.

Recent history

In September 2000, the building was attacked by unapprehended forces using a Russian-built RPG-22 anti-tank rocket, causing superficial damage. The Metropolitan Police recovered the discarded rocket launcher at Spring Gardens park in Vauxhall, as well as finding remains of the rocket which had exploded against an eighth floor window. Dissident Irish Republicans were believed to have been behind the attack. Writing in The Daily Telegraph after the attack, journalist Alan Judd referred to detractors who wished a less visible physical presence for SIS; writing that "Both sides of the Whitehall debate might now claim vindication by the rocket attack: on the one hand, the building's profile made it an obvious target; on the other, a headquarters with expensive security protection has been shown to be necessary."

On 1 June 2007, the building and its curtilage were designated as a protected site for the purposes of Section 128 of the Serious Organised Crime and Police Act 2005. The effect of the act was to make it a specific criminal offence for a person to trespass onto the site.

In August 2010, two men from North Wales were arrested after a parcel bomb was found at the SIS building's postal handling centre.

The Queen visited Vauxhall Cross for a second time in February 2006, and Charles, Prince of Wales visited in July 2008. In June 2013, Prince Harry visited Vauxhall Cross and was given a briefing on intelligence by staff. During the Thames Diamond Jubilee Pageant, part of the celebrations for the Diamond Jubilee of Elizabeth II in 2012, the London Philharmonic Orchestra played the "James Bond Theme" as they passed the building. The Daily Telegraph wrote that "Even MI6 managed to join the party – just. Its headquarters at Vauxhall sported a few discreet rows of bunting. But its balconies remained empty."

The building was lit with pink lights to raise awareness of breast cancer in 2013. In January 2013, the building was briefly put into a state of alert after the Vauxhall helicopter crash.

Cultural influence

Architectural criticism

The SIS building was reviewed favourably by Deyan Sudjic in The Guardian in 1992; he described it as an "epitaph for the architecture of the eighties". Sudjic wrote that "It's a design which combines high seriousness in its classical composition with a possible unwitting sense of humour. The building could be interpreted equally plausibly as a Mayan temple or a piece of clanking art deco machinery", and added that the most impressive thing about Farrell's design was the way he had not "confined himself to a single idea" as the building "grows and develops as you move around it". In their 2014 Guide to London's Contemporary Architecture, Kenneth Allinson and Victoria Thornton wrote:

Some see this building as Farrell's most controlled and mature building – a rich diet, certainly, but not a cacophony of rhetorical features, nor without the unselfconscious virtuosity which can uplift and excite. But it is undoubtedly too Gotham City for the taste of many. Farrell's many critics and opponents ... would call it a nightmare: a secret service fortress, provided by a private speculator, designed by an avowed populist, and sited on a most prominent river location. Indubitably, it is a bizarre phenomenon.

Feargus O'Sullivan on the other hand mentioned the nickname "Ceaușescu Towers" for the building, referring to the architecture of Socialist Romania, and derided the whole neighbourhood of newly constructed buildings in Vauxhall as "Dubai-on-Thames".

James Bond films

Vauxhall Cross has featured in several recent James Bond films, where it is depicted as the home base of the fictional 00 Section and its associated Q Branch. The building was first featured in GoldenEye (1995), and was depicted as having been attacked in The World Is Not Enough (1999), Skyfall (2012), and Spectre (2015). For Skyfall a 50-foot-high (15-metre) model of the building was constructed at Pinewood Studios. A special premiere of Skyfall was held at Vauxhall Cross for MI6 staff, who cheered when their headquarters was attacked in the film. Some filming for Spectre took place on the Thames near Vauxhall Cross in May 2015, with the fictional controlled demolition of the building playing a key role in the finale sequence of the film.

Silicon Integrated Systems (SiS; Chinese: 矽統科技; pinyin: Xìtǒng Kējì) is a company that manufactures, among other things, motherboard chipsets. The company was founded in 1987 in Hsinchu Science Park, Taiwan.

Business

In the late 1990s, SiS made the decision to invest in their own chip fabrication facilities. At the end of 1999, SiS acquired Rise Technology and its mP6 x86 core technology.

Mainboard chipsets

One of the most famous chipsets produced by SiS was the late 486-age chipset 496/497 which supported PCI bus among older ISA- and VLB-buses. Mainboards using this chipset and equipped with CPUs such as the Intel 80486DX4, AMD 5x86 or Cyrix Cx5x86 processors had performance and compatibility comparable with early Intel Pentium systems in addition to a lower price.

After this late success, SiS continued positioning itself as a budget chipset producer. The company emphasized high integration to minimize the cost to implement their solutions. As such, SiS one-chip mainboard chipsets that included integrated video, such as the Socket 7-based SiS 5596, SiS 5598, and SiS 530 along with the Slot 1-based SiS 620. These were some of the first PC chipsets with such high integration. They allowed entire system solutions to be built with just a mainboard, system RAM, and a CPU.

386 & 486 (Socket 1, 2, 3)

• SiS 310,320,330 "Rabbit"
• SiS 401/402 ISA
• SiS 406/411 EISA, Vesa Local Bus
• SiS 460 ISA, Vesa Local Bus
• SiS 461 ISA, Vesa Local Bus
• SiS 471 ISA, Vesa Local Bus
• SiS 496/497 ISA, VLB, PCI

Pentium (Socket 4,5,7)

• SiS 501/502/503 ISA, PCI
• SiS 5511/5512/5513 ISA, PCI
• SiS 5571 ISA, PCI
• SiS 5581 ISA, PCI
• SiS 5582 ISA, PCI
• SiS 5591/5595 ISA, PCI, AGP

The SiS 530 (Sindbad) with SiS 5595 southbridge supported Socket 7, SDRAM 1.5 GB max., a bus frequency from 66 MHz to 124 MHz, and can have from 2 to 8 MiB shared memory for an integrated AGP SiS 6306 2D/3D graphics controller. Includes integrated UDMA66 IDE controller. mainboards using the SiS 530 were positioned as cheap office platforms and paired often with low-cost chips from Intel competitors, such as the AMD K6 series or Cyrix 6x86. The graphics controller had Direct3D 6.0 and OpenGL support, although it was a very low-performance product for 3D acceleration.

SiS 540 (Spartan) integrates SiS 300 graphics controller.

Socket 370, Slot 1

• SiS 600/SiS 5595
• SiS 620/SiS 5595
• SiS 630 - includes North- and South bridges (SiS 960) and 2D/3D graphics controller (SiS 305) on one chip
• SiS 633
• SiS 635

Socket 478, Socket 775

SiS and ALi were the only two companies initially awarded licenses to produce third party chipsets for the Pentium 4. SiS developed the 648 chipset with this license (SiS 648 B Stepping supports Intel Hyper-Threading CPU on some motherboards like MSI 648 Max).

Socket A (Socket 462), Slot A

Socket 940, 754, 939, AM2

Memory support is dependent on the CPU

SiS created a multimedia chipset for the Xbox 360.

Southbridge chips

Paired with later SiS chipsets, such as the 661GX/761GX, which adopt a standard two-chip chipset design (instead of single-chip, like the older SiS 630/730 series chipsets). SiS southbridges can handle IDE, LAN (accompanied by a PHY chip), audio (with an AC'97 codec), along with other types of I/O. SiS' proprietary MuTIOL interconnect connects the southbridge chip to the northbridge, which contains the RAM controller (for chipsets targeted at Intel platforms) and interfaces with the CPU.

Graphics chipsets

Discrete 3D Graphics chips

Integrated 3D Graphics

• ¹Pixel shaders: vertex shaders: texture mapping units: render output units

Some cards contain a 3D graphics accelerator but it is only functional with the SiS's Proprietary Windows-only driver (the company does not provide documentation for others to write drivers). However, the Linux kernel includes a working third party driver that, while not supporting 3D gaming, makes the cards usable under Linux.

The SiS 630 and SiS 730 are a family of highly integrated chipsets for Intel (Slot 1/Socket 370) and AMD (Slot A/Socket A) respectively. At the time of release they were unique in that they not only provided VGA, Audio, LAN, IDE and USB functionality on board, but were also in a single-chip solution. At the time of release (1999) most chipsets were composed of physically separate north-bridge and south-bridge chips (technically these still existed in the SiS 630/730 but were contained in a single package). Only later have single-chip solutions become popular in the mainstream, with chipsets such as the nVidia nForce4.

VGA Core (SiS 305)

• Hardware Acceleration (Motion Compensation and iDCT) for DVD Playback.
• Ultra-AGP Architecture.
• Fully DirectX 7.0 Compliant Graphics Engine.
• Resolution Up to 1920x1200 8bpp/16bpp 60 Hz NI.
• Optional Extended Graphics Memory (EGM) On board for 128-bit Memory Accessing.
• Supports VESA DDC1, DDC2B & DDC 3.0.
• Driver Support for OS/2(R), Windows(R) 95/98/ME, Windows NT(R) 4.0, Windows(R) 2000/XP.
• Supports SiS 301 Video Bridge Interface for Dual Display.
• NTSC/PAL TV or Secondary CRT monitor or TFT Digital LCD Monitor.

The video core in the SiS 630/730 is based on the 128-bit SiS 305. The VGA core is capable of using either its own dedicated local memory (giving a 128-bit memory interface) or taking a chunk out of system memory (usually configurable from between 8 MB to 64 MB, giving 64-bit memory interface). In the majority of systems it is configured to use system memory since to get local memory support it was necessary to use a special card which fitted into the proprietry VB slot which is impossible in laptops, and for desktop systems didn't make any sense once cheap AGP graphics cards became available offering superior performance. The onboard adapter competed well against the Intel i810 on Intel platforms and the VIA Twister on AMD both in terms of features and performance.

Unlike the Intel i810, the SiS 630 renders 3D in 32-bit colour (although the performance was quite poor). There was also support for full hardware decoding of MPEG2 which gave CPU usage of around 5-10% when watching DVDs with suitable software (Cyberlink PowerDVD 5 or VideoLAN Media Player). Access to the acceleration is provided via DXVA under Windows 2000/XP.

Another interesting feature is that the SiS 30x core supports two independent overlay surfaces, one for each output. This means that it is possible to view videos on both the primary monitor (e.g. the built in screen on a notebook) and on a TV-Out or secondary monitor output. Most other graphics cards only have one overlay surface or in some cases will clone the same overlay.

The memory bandwidth is shared between the graphics adapter and the rest of the system. Therefore, the system performance is dependent on the resolution and colour depth that is in use. Whilst this would give comparatively poor scores in pure memory throughput benchmarks (a SiS 630 system will show around 470 MB/s of memory read throughput compared to around 800 MB/s on a similar system with discrete graphics) the real-world performance in office applications was very good with systems (particularly budget notebooks) based around the chipset frequently walking away with "best buy" awards.

Audio (SiS 7018)

• 64-voice Polyphony 'Wavetable' sample-based Synthesizer.
• DirectSound 3D Accelerator for IID, IAD and Doppler Effects.
• Full-duplex, Independent Sample Rate Converter for Audio Recording and Playback.
• Supports 2/4/6 Speakers Output with Optional VirtualFX, VirtualAC3.
• AC'97 V2.1 Interface for External Audio Codec.
• SoundBlaster Pro/16 Compliant.
• Full Duplex VirtualPhone Speaker Phone with Modem Capable AC'97.
• V.90 Software Modem Compliant.
• Driver Support for Windows 95/98/ME, NT 4.0, Windows 2000/XP.

Unlike the later SiS 735 chipset which used the host-processed SiS 7012, the SiS 630/730 featured the fully hardware accelerated SiS 7018 core which itself is a design licensed from Trident, sold as the Trident 4DWave (the same design was also licensed by ALi for use in their 5451 chipset). The Windows 95 VxD drivers take advantage of the hardware acceleration, and there is also SoundBlaster 16 emulation for MS-DOS based games.

Unfortunately SiS chose to drop all of the hardware features from Windows 2000 onwards, treating it as a simpler AC97 host processed solution, as the SiS 7012. At the time of writing there is still no support for the hardware DirectSound, mixing or MIDI features that this chip provides in the WDM driver.

10/100 Fast Ethernet (SiS 900)

• IEEE802.3/IEEE802.3u Compatible, 10BASE-T/100BASE-TX Standards Support.
• Supports On-Now, Wake-On-LAN, PCI Power Management 1.1.
• Driver Support for Windows 95/98/ME, NT 4.0, Windows 2000/XP, OS/2, Netware, ODI, SCO Unix, Netware & Linux.

Onboard Ethernet functionality is provided by an SiS 900 compatible controller providing both 10 Mbit/s and 100 Mbit/s with auto-sensing.

USB (SiS 7001)
The SiS 630/730 provides two USB 1.1 controllers called the SiS 7001, theoretically allowing 2 12 Mbit/s shared amongst up to 6 physical USB ports. On some boards or notebook systems only one of the controllers is used, with the other one going unused.

IDE (SiS 5513)
The IDE controller on the SiS 630/730 provides support for up to UDMA/100 depending on the specific variant. The IDE controller connects to the "north-bridge" via a dedicated 133 MB/s link, separate from the second 133 MB/s link between the north bridge and other PCI devices. This is beneficial in two ways; firstly IDE performance shouldn't be affected by other PCI devices, and similarly IDE transfers shouldn't affect other devices such as sound cards.

Other Hardware Features
In addition to the features listed above, the SiS 630/730 has support for legacy ports including SPP/ECP/EPP parallel port, 2 serial ports and Fast Infrared/IrDA. There is also a modem interface for HSP AMR modems such as those from SmartLink and PCTel.

Kiss×sis (stylized as kiss×sis; pronounced "kiss sis") is a Japanese manga series written and illustrated by Bow Ditama. It began serialization in Kodansha's Bessatsu Young Magazine in December 2005. It was then moved and serialized in Weekly Young Magazine from 2008 to 2009, and was serialized in Monthly Young Magazine from 2009 to 2021. Kodansha collected its chapters in twenty-five tankōbon volumes. It was adapted into an original video animation series, released from December 2008 to April 2015. A 12-episode anime television series by Feel aired from April to June 2010 on AT-X.

Plot

Keita Suminoe is a third-year Japanese middle school student living with his father, stepmother, and older twin stepsisters, Ako and Riko. Since the remarriage of their parents at childhood, the siblings have always been affectionately close and supportive of one another. Nowadays the trio see their opposites in a noticeably less platonic fashion; Ako and Riko frequently flirt and lust after Keita while, much to his stress, he fights the urge to give in to them.

Characters

Keita Suminoe (住之江 圭太, Suminoe Keita)

Voiced by: Ken Takeuchi

Keita Suminoe is a 15-year-old third-year middle school student who is part of a blended family after his father remarried some years previously (Keita's mother having died when he was young). He was raised with two stepsisters, Ako and Riko, who are a year older than he is and have developed more-than-filial feelings for him. As a result, now that they are high school age, Keita finds it increasingly difficult to retain his modest, dignified morals; especially when exposed to his parents' shockingly permissive attitudes. A track and field club member, Keita is more athletic than he is academic; however he strives to be, and eventually is, accepted to the same high school as his stepsisters. There, he is a first-year high school student in the same class as Miharu, with Yuzuki Kiryu as their homeroom teacher.

Ako Suminoe (住之江 あこ, Suminoe Ako)

Voiced by: Ayana Taketatsu

Bright and cheery, Ako Suminoe is a 16-year-old first-year high school student who is one of two stepsisters to Keita and twin sister to Riko. The more intellectual of the pair, Ako is educated, maternal, responsible, the manager of the Student Council General Affairs, skilled at cooking and homemaking, and endeavors to maintain a prim and proper demeanor. In spite of this imposing façade however, she is outwardly emotional, childish, whiny, reluctant, easily embarrassed and perverse; her most well-known open secret. Having grown up with Keita since toddlerhood, Ako is altruistic and, of course, in love with him. As such she is not afraid of abusing her authority on the student council to either make a pass at Keita, or cover up embarrassing occurrences.

Riko Suminoe (住之江 りこ, Suminoe Riko)

Voiced by: Yuiko Tatsumi

Riko Suminoe is a 16-year-old first-year high school student and second stepsister to Keita. Though less academically accomplished than her twin, Riko is cunning, insightful, crafty, an active member of the Disciplinary Committee, and boldly open about her personal life and sexuality. Unlike Ako, she is very poor at cooking and it always turns out to be inedible and when she feeds it to Keita, he spits the food in her face in disgust, much to her anguish. Surprisingly, she cannot bring herself to kiss Keita in front of others. In contrast to Ako, she is highly skilled in physical activities and sometimes helps out with various sports clubs who need another person temporarily for training. She is known however to be soft-spoken, clumsy, temperamental, and gets drunk more easily than her sister and Keita. Riko is most recognized for wearing an adhesive bandage on her left cheek, ostensibly to cover up a scar that from when Keita threw a toy at her when they were children. There may not even be a scar, but Riko never lets anyone see what is under the bandage. It is hinted that Riko keeps wearing a bandage as a visible reminder for Keita to keep thinking about her. Riko is ardently fond of her stepbrother and forever fighting with Ako over his affections.

Miharu Mikuni (三国 美春, Mikuni Miharu)

Voiced by: Yoriko Nagata (anime), Tomoko Nakamura (OAD 10–11)

Miharu Mikuni is a third-year middle school student who enters into the same high school class as Keita. A fairly quiet and unassuming character, she comes to his attention when she delivers Keita his entrance exam results; having passed, he joyfully befriends her. Unlike the other girls, Miharu is comparatively meek, easily intimidated and predisposed to anxiety; as such, she suffers from enuresis (which becomes a running gag in the series). Her relationship with Keita is mostly platonic; what feelings she does have for him are generally overshadowed by the not-too-greatly over-imagined images she has of him and his stepsisters. She sometimes fantasizes about Keita making non-consensual advances against her, but initially does not seem have any romantic interest in him. This situation may not last as she seems to be (glacially) slowly developing a romantic interest in him after he helps her out of various (and sometimes extremely embarrassing) situations (that are usually but unintentionally caused by either the twins or Mikazuki) and keeps his mouth shut about them. Her fondness for Keita grew noticeably when he 'tripped' during a race (actually hurting his leg a little) so that she could finish first and experience what it felt like to win a sporting event. Of the entire cast, Miharu is the only bespectacled female character. Later on, her feelings for Keita grow and she becomes more aggressive in pursuing him, much to the chagrin of Ako and Riko.

Mikazuki Kiryū (桐生 三日月, Kiryū Mikazuki)

Voiced by: Asuka Ōgame

Peppy and outgoing, Mikazuki Kiryu is a second-year middle school student and the younger sister of Yuzuki Kiryu. She enters her third year of middle school when Keita starts his first year in high school. She is much more mature for her age than her sister is, and tends to keep a mostly level head when her sister is losing hers. An underclassman to the rest of the cast, Mikazuki looks up to everyone, especially Keita, who she has a crush on. However, she seems to be just as interested in amusing herself by watching the antics and reactions of others as in actually winning him over. She considers her sister, Yuzuki, and Keita to be two of a kind, well suited for each other, and enjoys watching them try to act like a normal teacher and student. She becomes one of the few characters outside of Ako and Riko to discover that Yuzuki and Keita are secretly in a relationship when she bursts in on the two making out in Yuzuki's apartment. She seems to develop some feelings for Keita herself after the group trip to the beach. She also shares a certain genetic condition with her sister that is revealed when the girls take a bath during the beach trip.

Yūzuki Kiryū (桐生 夕月, Kiryū Yūzuki)

Voiced by: Asami Imai

Yuzuki Kiryu is a recently hired 24-year-old homeroom and Japanese History teacher at the fictional Gakushū Senior High, and the older sister of Mikazuki. Prior to working at the school, she had a job at a clothing store, which is where Keita first encountered her. While she constantly berates herself whenever she makes mistakes, she is a caring teacher who can lay down the law when necessary but tends to get herself and others in trouble when she acts impulsively over perceived misconduct without finding out the full story. Single, unmarried, independent, and noticeably eccentric, she is initially disgusted with Keita and his relationship with Ako and Riko, to the point of unduly crusading against it. Ultimately, and despite her age difference, she develops conflicting feelings for Keita herself. An obsessive fan of anime, manga and cosplay, Yuzuki's apartment contains a large collection of merchandise, books, games and posters; a particularly favored theme of hers being samurai. She is so obsessed that her parents forced her to either give up her hobbies permanently or get a place of her own (which she did). She often has to eat cheap ramen as she spends most of her money on so much paraphernalia to the point that it clutters up her apartment and she cannot invite anyone inside without them discovering her hobby. Much to her humiliation, Yuzuki is a virgin. In the manga, Yuzuki and Keita eventually become closer, admit their mutual feelings for one another, and start dating in secret, a fact only known by Ako and Riko (but eventually discovered by Mikazuki and suspected by other characters), who despite being angry at her for getting involved with her own student, respect his decision, stating that in the end he will return to their side. Keita's parents also know about their relationship and accepted it. Later on, she breaks up with Keita after escaping to Hokkaido as she did not want to be his girlfriend anymore.

Toda Edogawa (江戸川 戸田, Edogawa Toda)

Voiced by: Kiyotaka Furushima

Another friend of Keita's from school.

Anime

It was announced in June 2008 that an animated adaption of Kiss×sis would be produced by Feel. On December 22 of that year, the first OVA was released, bundled with the third volume of the manga, directed by Munenori Nawa. Subsequent releases were packaged with subsequent volumes of the manga. The 12th and last episode was released on April 6, 2015. The opening and closing themes for the OVA include "Our Honey Boy" (ふたりのハニーボーイ, Futari no Hanibōi) by Ayana Taketatsu and Yuiko Tatsumi and "Starry Sky Story" (星空物語, Hoshizora Monogatari) by Nana Takahashi, respectively.

A 12-episode anime television series adaptation of the manga aired on AT-X from April 5 to June 21, 2010. A censored pre-release of the first episode aired online on March 28, 2010. The opening theme is "Balance Kiss" (バランスKISS, Baransu Kisu) performed by Ayana Taketatsu and Yuiko Tatsumi, and the ending theme is "Our Steady Boy" by Yui Ogura and Kaori Ishihara.

The SiS 300/SiS 301 is a graphics processing unit that was manufactured by Silicon Integrated Systems. This GPU targeted mainstream commercial and consumer markets.

Overview

Following the successful SiS 6326 in 1998, SiS introduced the SiS 300 as its replacement. The 3D performance was improved five times over the previous GPU, although still considered slow, yet a value solution as a display chip for users that don't use 3D-intensive applications.

The SiS 301 was a companion chip that enabled support for TVs and digital flat panel monitors.

Architecture

This chip featured a 128-bit memory bus that could access 4/8/16/32/64 MB of RAM, DirectX 6.0 support with multi-textures capability, DVD decoder and an AGP 2x/4x bus to the system.

The SiS 300 was manufactured in a 250 nm process and packaged in a 365 pin PBGA. The SiS 301 was packaged in a 100 pin TQFP.
