R3000
The R3000 is a 32-bit RISC microprocessor chipset developed by MIPS Computer Systems that implemented the MIPS I instruction set architecture (ISA). Introduced in June 1988, it was the second MIPS implementation, succeeding the R2000 microprocessor, R2000 as the flagship MIPS microprocessor. It operated at 20, 25 and 33.33 MHz. The MIPS 1 instruction set is small compared to those of the contemporary 80x86 and 680x0 architectures, encoding only more commonly used operations and supporting few addressing modes. Combined with its fixed instruction length and only three different types of instruction formats, this simplified instruction decoding and processing. It employed a 5-stage instruction pipeline, enabling execution at a rate approaching one instruction per cycle, unusual for its time. This MIPS generation supports up to four co-processors. In addition to the CPU core, the R3000 microprocessor includes a Control Processor (CP), which contains a Translation Lookaside Buffe ...

DECstation
The DECstation was a brand of computers used by Digital Equipment Corporation, DEC, and refers to three distinct lines of computer systems—the first released in 1978 as a word processing system, and the latter (more widely known) two both released in 1989. These comprised a range of computer workstations based on the MIPS architecture and a range of PC compatibles. The MIPS-based workstations ran ULTRIX, a DEC-proprietary version of Unix, UNIX, and early releases of OSF/1. DECstation 78 The first line of computer systems given the DECstation name were word processing systems based on the PDP-8. These systems, built into a VT52 computer terminal, terminal, were also known as the VT78. DECstation RISC workstations History The second (and completely unrelated) line of DECstations began with the DECstation 3100, which was released on 11 January 1989. The DECstation 3100 was the first commercially available RISC-based machine built by DEC. This line of DECstations was t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MIPS Computer Systems
MIPS Tech LLC, formerly MIPS Computer Systems, Inc. and MIPS Technologies, Inc., is an American fabless semiconductor design company that is most widely known for developing the MIPS architecture and a series of RISC CPU chips based on it. MIPS provides processor architectures and cores for digital home, networking, embedded, Internet of things and mobile applications. MIPS was founded in 1984 to commercialize the work being carried out at Stanford University on the MIPS architecture, a pioneering RISC design. The company generated intense interest in the late 1980s, seeing design wins with Digital Equipment Corporation (DEC) and Silicon Graphics (SGI), among others. By the early 1990s the market was crowded with new RISC designs and further design wins were limited. The company was purchased by SGI in 1992, by that time its only major customer, and won several new designs in the game console space. In 1998, SGI announced they would be transitioning off MIPS and spun off the c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ardent Computer
Stardent Computer, Inc. was a manufacturer of graphics supercomputer workstations in the late 1980s. The company was formed in 1989 when Ardent Computer Corporation (formerly Dana Computer, Inc.) and Stellar Computer Inc. merged. Both of the founding companies had formed in 1985, intending to address different market niches; Stellar concentrated on high-performance workstation type machines, while Ardent developed a custom vector processor that allowed it to compete with large supercomputers for graphics-related tasks. Ardent had considered a workstation entry of their own to compete with Stellar, but the merger ended the need for a second design. The company was never able to compete successfully with larger vendors and its sales peaked at around $40 million in 1990. The company successfully sold off some of its technologies before being broken up completely in 1994.
