Bipolar Integrated Technology, Inc. (BIT), later Bit, Inc., was a privately held [2] semiconductor company based in Beaverton, Oregon, which sold products implemented with emitter-coupled logic technology. The company was founded in 1983 by former Floating Point Systems, Intel, and Tektronix engineers. [1] [3] [4] [5] The company, which occupied a 46,000-square-foot manufacturing facility manufacturing facility at the Oregon Graduate Center, [6] raised $36 million in start-up capital within three years of its foundation. [7]
The initial product was a floating-point co-processor chipset. Later, the company produced the B5000 SPARC ECL microprocessor (never reached production in a Sun Microsystems product, though used by Floating Point Systems). [8] They also produced the R6000 MIPS ECL microprocessor, which did reach production as a MIPS minicomputer. [9] Initial yields of the R6000 were very poor, leading to parts shortages for MIPS Computer Systems; the latter company attributed their first quarterly loss in October 1990 to BIT. [10] The two signed an agreement in June 1991 to allow BIT to market the R6000 on the open market, dissolving the previous exclusivity agreement with MIPS. [11]
Under its new president Fred Hanson, BIT had its first profitable year in 1991, [11] reaching peak revenues of $20 million. Revenues dropped the following year to about $10 million, however, after it had lost four of its largest customers, including MIPS, Floating Point, and Control Data. [12] The company eventually entered the telecommunications market with Asynchronous Transfer Mode (ATM) devices and Ethernet switches. The company was eventually acquired by PMC-Sierra in September 1996 for these later communications products. [1] [13]
A microprocessor is a computer processor where the data processing logic and control is included on a single integrated circuit (IC), or a small number of ICs. The microprocessor contains the arithmetic, logic, and control circuitry required to perform the functions of a computer's central processing unit (CPU). The IC is capable of interpreting and executing program instructions and performing arithmetic operations. The microprocessor is a multipurpose, clock-driven, register-based, digital integrated circuit that accepts binary data as input, processes it according to instructions stored in its memory, and provides results as output. Microprocessors contain both combinational logic and sequential digital logic, and operate on numbers and symbols represented in the binary number system.
The history of computing hardware starting at 1960 is marked by the conversion from vacuum tube to solid-state devices such as transistors and then integrated circuit (IC) chips. Around 1953 to 1959, discrete transistors started being considered sufficiently reliable and economical that they made further vacuum tube computers uncompetitive. Metal–oxide–semiconductor (MOS) large-scale integration (LSI) technology subsequently led to the development of semiconductor memory in the mid-to-late 1960s and then the microprocessor in the early 1970s. This led to primary computer memory moving away from magnetic-core memory devices to solid-state static and dynamic semiconductor memory, which greatly reduced the cost, size, and power consumption of computers. These advances led to the miniaturized personal computer (PC) in the 1970s, starting with home computers and desktop computers, followed by laptops and then mobile computers over the next several decades.
Silicon Forest is a nickname for the Washington County cluster of high-tech companies located in the Portland metropolitan area in the U.S. state of Oregon, and most frequently refers to the industrial corridor between Beaverton and Hillsboro in northwest Oregon.
The Indy, code-named "Guinness", is a low-end multimedia workstation introduced on July 12, 1993. Silicon Graphics Incorporated (SGI) developed, manufactured, and marketed Indy as the lowest end of its product line, for computer-aided design (CAD), desktop publishing, and multimedia markets. It competed with Intel x86 computers, and with Windows and Macintosh, including using their files and running their applications via software emulation. It is the first computer to come standard with a video camera, called IndyCam. Indy was repackaged as a server model called Challenge S. Indy was discontinued on June 30, 1997 and support ended on December 31, 2011.
PMC-Sierra was a global fabless semiconductor company with offices worldwide that developed and sold semiconductor devices into the storage, communications, optical networking, printing, and embedded computing marketplaces.
Quantum Effect Devices (QED) was a microprocessor design company incorporated in 1991 as Quantum Effect Design. It was based in Palo Alto, California.
Floating Point Systems, Inc. (FPS), was a Beaverton, Oregon vendor of attached array processors and minisupercomputers. The company was founded in 1970 by former Tektronix engineer Norm Winningstad, with partners Tom Prince, Frank Bouton and Robert Carter. Carter was a salesman for Data General Corp. who persuaded Bouton and Prince to leave Tektronix to start the new company. Winningstad was the fourth partner.
The R4000 is a microprocessor developed by MIPS Computer Systems that implements the MIPS III instruction set architecture (ISA). Officially announced on 1 October 1991, it was one of the first 64-bit microprocessors and the first MIPS III implementation. In the early 1990s, when RISC microprocessors were expected to replace CISC microprocessors such as the Intel i486, the R4000 was selected to be the microprocessor of the Advanced Computing Environment (ACE), an industry standard that intended to define a common RISC platform. ACE ultimately failed for a number of reasons, but the R4000 found success in the workstation and server markets.
The R5000 is a 64-bit, bi-endian, superscalar, in-order execution 2-issue design microprocessor, that implements the MIPS IV instruction set architecture (ISA) developed by Quantum Effect Design (QED) in 1996. The project was funded by MIPS Technologies, Inc (MTI), also the licensor. MTI then licensed the design to Integrated Device Technology (IDT), NEC, NKK, and Toshiba. The R5000 succeeded the QED R4600 and R4700 as their flagship high-end embedded microprocessor. IDT marketed its version of the R5000 as the 79RV5000, NEC as VR5000, NKK as the NR5000, and Toshiba as the TX5000. The R5000 was sold to PMC-Sierra when the company acquired QED. Derivatives of the R5000 are still in production today for embedded systems.
The transistor count is the number of transistors in an electronic device. It is the most common measure of integrated circuit complexity. The rate at which MOS transistor counts have increased generally follows Moore's law, which observed that the transistor count doubles approximately every two years. However, being directly proportional to the area of a chip, transistor count doesn't represent how advanced corresponding manufacturing technology is, which is better characterized by transistor density instead.
The R6000 is a microprocessor chip set developed by MIPS Computer Systems that implemented the MIPS II instruction set architecture (ISA). The chip set consisted of the R6000 microprocessor, R6010 floating-point unit and R6020 system bus controller. The R6000 was the first implementation of the MIPS II ISA.
The R2000 is a 32-bit microprocessor chip set developed by MIPS Computer Systems that implemented the MIPS I instruction set architecture (ISA). Introduced in January 1986, it was the first commercial implementation of the MIPS architecture and the first commercial RISC processor available to all companies. The R2000 competed with Digital Equipment Corporation (DEC) VAX minicomputers and with Motorola 68000 and Intel Corporation 80386 microprocessors. R2000 users included Ardent Computer, DEC, Silicon Graphics, Northern Telecom and MIPS's own Unix workstations.
