- Weitek war eine US-amerikanische Firma, die in den 1980er Jahren mathematische Koprozessoren für IBM-kompatible PC-Systeme (für 386er den 3167, für 486er den 4167) und Workstations sowie Grafikkarten-Prozessoren (WEITEK 9000 bzw. 9100 evtl. mit Video-Coprozessor) entwarf und produzierte. Weitek ging in Konkurs und wurde von der US-amerikanischen Firma Rockwell Semiconductor aufgekauft.
- Weitek（ウェイテック、Weitek Corporation）は、かつて存在したアメリカの半導体製造企業。特に他社のCPU向けのFPUを設計開発することを得意とした。 1980年代中盤、Weitekの設計したものは各種のハイエンドマシンや並列処理スーパーコンピュータなどで使われている。 1990年代初め、各CPUはFPUを含めて設計されるようになってきたため、Weitekは汎用CPUとグラフィックドライバの市場に打って出ようとした。 1995年、Weitekはほとんど倒産寸前となった。1996年後半には、残った資産はロックウェルの半導体部門に買収され、Weitekは消えていった。
- Weitek Corporation fue una compañía de desarrollo de chips originalmente concentrada en las unidades de coma flotante para algunos fabricantes de CPUs. A principios y mediados de los años 1980 los diseños de Witek se encontraban en muchos superordenadores que llevaban a cabo computación paralela. Para el 1995 fue muriendo en su mayor parte, y a finales del 1996 lo restante fue comprado por Rockwell Semiconductor y rápidamente desapareció.
- Weitek公司曾是家知名的晶片設計業者，該公司最初專注在多種商用微處理器（CPU）的浮點運算單元（FPU）設計，而在1980年初期至中期Weitek公司為平行處理式的超級電腦提供多種高階運算設計。到了1990年初期由於多數的CPU已內建FPU，且基本上FPU功效為免費奉送，這迫使Weitek公司進行一連串的嘗試，嘗試跨進一般用途性的CPU及GPU的市場領域。此後到1995年Weitek近乎停止營運，隨後在1996年由洛克威爾國際（Rockwell International）的半導體系統部門所收購，並快速從市場上消失。
- Weitek Corporation was a chip-design company that originally concentrated on floating point units for a number of commercial CPU designs. During the early to mid-1980s, Weitek designs could be found powering a number of high-end designs and parallel processing supercomputers. During the early 1990s most CPU designs started including FPUs built-into the system, basically “for free”, and Weitek made a series of attempts to break into the general CPU and graphics driver market. By 1995 the company was almost dead, and in late 1996 the remains were purchased by Rockwell's Semiconductor Systems and quickly disappeared. Weitek started in 1981, when several Intel engineers left to form their own company. Weitek developed math coprocessors for several systems, including those based on the Motorola 68000 family, the 1064, and for Intel based i286 systems, the 1067. Intel's own FPU design for the i386 fell far behind in development, and Weitek delivered the 1167 for them. Later upgrades to this design led to the 2167, 3167 and 4167. Weitek would later deliver similar FPUs for the MIPS architecture, known as the XL line. Weitek FPUs were somewhat odd, supporting single precision math only, although doing so at very fast speeds. As orders increased for supercomputer applications, Weitek found themselves seriously disadvantaged by their fab, which was becoming rather “outdated”. HP approached them with a deal to use their newer fabs. This proved advantageous for both, and soon HP’s fabs were open to anyone. Weitek also worked with HP on the design of their latest PA-RISC design, and sold their own version known as the RISC 8200 which was sold as an embedded design and had some use in laser printers. In the late 1980s Weitek saw a new opportunity, and started developing frame buffers for Sun Microsystems workstations. In the early 1990s they also introduced the SPARC POWER µP (as in “power-up”, and technically referred to as WTL 8601), a pin-compatible version of the SPARC processor. The µP could be dropped into existing SPARCstation 2 and SPARCstation IPX workstations and ran at 80 MHz, double the clock speed of the CPUs it replaced. The 8701 ran twice as fast internally, providing a boost of about 50-60 % in overall speed, due to the bus not getting any faster. However they did not pursue this concept with later generations of SPARC processors. Weitek turned their frame-buffer experience to the PC market in the early 90s, and introduced a series of SVGA multimedia chipsets known as the “POWER” systems. Consisting of two chips, one drawing the graphics known as the P9000 and another handling the output, the VideoPower 5x86, the POWER series was used in a number of 3rd party designs based on the VESA Local Bus standard. The P9001 moved to PCI and became fairly popular in 1994, known as the Viper in designs from Diamond and Orchid. The final generation, the P9100, combined the P9001 and 5286 into a single chip. Weitek adaptors were fairly successful in the early days of the 486 market, but fell from use as less expensive systems were introduced by a host of new players in the mid-90s. Weitek attempted to re-enter at the low-end of the market with their W464 (486) and W564 (P5) systems which used the host machines RAM as the frame buffer to lower costs. These were one of the reasons the company was purchased by Rockwell shortly after they shipped.
- L'azienda informatica californiana Weitek Corporation ha operato come produttore di unità di calcolo in virgola mobile (FPU) per workstation, supercomputer e personal computer dal 1981 al 1990-1991; come produttore di GPU e chipset per schede madri tra il 1991 e il 1996. Costituitasi nel 1981, Weitek Corporation produce per tutti gli anni ottanta, FPU ad alte prestazioni sia per schede video che per CPU di workstation e supercomputer. Per il mercato PC, Weitek produce FPU da abbinare a processori Intel quali i286, i386 e l'i486 nella versione SX. Con la progressiva integrazione, nei primi anni '90, delle FPU all'interno delle CPU, Weitek perde il suo mercato di riferimento e cerca di riposizionarsi come produttore di framebuffer per workstation SPARC. Successivamente, nel 1991, Weitek inizia lo sviluppo e la produzione di GPU con la serie Power 9000, e di PC chipset con i modelli W464 e W564, entrambi con GPU integrata che sfruttano la RAM di sistema come memoria video, progettati per schede madri Intel 486 e Pentium compatibili. In progressivo declino, verso la metà degli anni '90, Weitek entra in crisi avviandosi verso il fallimento. Acquisita nel 1996, da parte del produttore di semiconduttori Conexant System, interessato alle tecnologie sviluppate da Weitek nel campo dei framebuffer, l'azienda viene disciolta e cessa ogni attività.
- Weitek Corporation var en produsent av integrerte kretser, mikroprosessorer og koprosessorer. Selskapet ble etablert i 1981 av ingeniører som hadde arbeidet for Intel. Weitek produserte desimaltall koprosessorer for en rekke CPUer, deriblant WTL 1064 for Motorola 68000 og WTL 1067 for Intel 80286. WTL 1167 for Intel 80386 – og etterfølgerne WTL 2167 og WTL 3167, konkurrerte med Intels egen koprosessor Intel 80387. Endog etter at Intel integrerte koprosessoren i Intel 80486, lanserte Weitek koprosessoren WTL 4167 for å øke hastigheten på desimaltallsberegninger i 80486-baserte datamaskiner. Weitek produserte også tre desimaltall koprosessorer for MIPS-arkitekturen kalt henholdsvis XL-3132, XL 3364 og XL-8032. Weitek produserte også brikkesett til personlige datamaskiner basert på x86-arkitekturen. Disse hadde benevnelsene W464, W564, WTL2264 og WTL2265. På 1980-tallet inngikk Weitek en avtale med Hewlett-Packard om å benytte deres fabrikker til produksjonen av brikker. Weitek samarbeidet med Hewlett-Packard i utformingen av PA-RISC arkitekturen. De lanserte også RISC-prosessorene Weitek 8200 og Weitek 8220, basert på HP PA-RISC. En variant av Weitek 8200 som kjørte i 7.25 Mhz, ble benyttet som en innebygd prosessor i laserprinteren Apple LaserWriter Pro 810. Weitek 8220 ble lansert i 16, 20 og 25 MHz. I begynnelsen av 1990-tallet forsvant behovet for eksterne koprosessorer, etterhvert som de ble integrerte i de fleste mikroprosessorer. Ved lanseringen av Intel 80486 DX2 var f. eks. WTL 4167 blitt helt overflødig og ute av stand til å konkurrere med den integrerte koprosessoren. På slutten av 1980-tallet begynte Weitek å produsere frame buffer for arbeidsstasjoner fra Sun Microsystems. Tidlig på 1990-tallet introduserte de også RISC-prosessoren WTL 8601 SPARC POWER µP, som var pinnekompatibel med eksisterende SPARC. På SPARCStation 2 ble en utgave i 40 MHz benyttet som oppgraderings-prosessor, på lignende vis som Fujitsus TurboSPARC ble benyttet til å erstatte microSPARC II. WTL 8601 SPARC POWER µP var 50 % raskere enn SPARC-prosessoren som den erstattet. Etterfølgeren WTL 8701 SPARC POWER µP var klokkedoblet, og sørget for en ytelsesøkning på 50-60%. Tidlig på 1990-tallet lanserte Weitek en serie SVGA multimedia brikkesett kjent som «POWER-systemer». De bestod av to brikker, der P9000-serien (P9000, P9001, P9100 og P9130) tegnet grafikken, mens produktserien VideoPower 5x86 (VideoPower 5086, VideoPower 5186 og VideoPower 5286) håndterte overføringen til skjerm. P9000 ble brukt av en rekke produsenter i sidekort for VESA lokalbuss. P9001 baserte seg på PCI og ble i 1994 benyttet i PCI-kort produsert av Diamond Multimedia og Orchid Technology. P9100 integrerte P9001 og VideoPower 5x86 i én enkel brikke, og ble mye brukt på 80486-baserte datamaskiner. Den 8. juni 1995 lanserte Weitek en 64-bit PCI-basert VGA-kontroller for 80486 kalt W464, og en Pentium-basert kontroller kalt W564. Dette var grafikk-kontrollere som benyttet 1-2 MB av vertsmaskinens DRAM i en såkalt unified memory architecture (UMA). Den 12. desember 1996 ble Weitek oppkjøpt av Rockwell Semiconductor Systems for ca $3,000,000.
