P2SC
The POWER2, originally named RIOS2, is a processor designed by IBM that implemented the POWER instruction set architecture. The POWER2 was the successor of the POWER1, debuting in September 1993 within IBM's RS/6000 systems. When introduced, the POWER2 was the fastest microprocessor, surpassing the Alpha 21064. When the Alpha 21064A was introduced in 1993, the POWER2 lost the lead and became second. IBM claimed that the performance for a 62.5 MHz POWER2 was 73.3 SPECint92 and 134.6 SPECfp92. The open source GCC compiler removed support for POWER1 (RIOS) and POWER2 (RIOS2) in the 4.5 release. Description Improvements over the POWER1 included enhancements to the POWER instruction set architecture (consisting of new user and system instructions and other system-related features), higher clock rates (55 to 71.5 MHz), an extra fixed point unit and floating point unit, a larger 32 KB instruction cache, and a larger 128 or 256 KB data cache. The POWER2 was a mult ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IBM POWER Instruction Set Architecture
IBM POWER is a reduced instruction set computer (RISC) instruction set architecture (ISA) developed by IBM. The name is an acronym for ''Performance Optimization With Enhanced RISC''. The ISA is used as base for high end microprocessors from IBM during the 1990s and were used in many of IBM's servers, minicomputers, workstations, and supercomputers. These processors are called POWER1 (RIOS-1, RIOS.9, RSC, RAD6000) and POWER2 (POWER2, POWER2+ and P2SC). The ISA evolved into the PowerPC instruction set architecture and was deprecated in 1998 when IBM introduced the POWER3 processor that was mainly a 32/64-bit PowerPC processor but included the IBM POWER architecture for backwards compatibility. The original IBM POWER architecture was then abandoned. PowerPC evolved into the third Power ISA in 2006. IBM continues to develop PowerPC microprocessor cores for use in their application-specific integrated circuit (ASIC) offerings. Many high volume applications embed PowerPC cores. ...

IBM Power Microprocessors
IBM Power microprocessors (originally POWER prior to Power10) are designed and sold by IBM for servers and supercomputers. The name "POWER" was originally presented as an acronym for "Performance Optimization With Enhanced RISC". The Power line of microprocessors has been used in IBM's RS/6000, AS/400, pSeries, iSeries, System p, System i, and Power Systems lines of servers and supercomputers. They have also been used in data storage devices and workstations by IBM and by other server manufacturers like Bull and Hitachi. The Power family was originally developed in the late 1980s, and remains under active development. In the beginning, they implemented the POWER instruction set architecture (ISA), which evolved into PowerPC and later into Power ISA. In August 2019, IBM announced it would open source the Power ISA. As part of the move, it was also announced that administration of the OpenPOWER Foundation will now be handled by the Linux Foundation. History Early developme ...

RS/6000
The RISC System/6000 (RS/6000) is a family of Reduced instruction set computer, RISC-based Unix Server (computing), servers, workstations and supercomputers made by IBM in the 1990s. The RS/6000 family replaced the IBM RT PC computer platform in February 1990 and was the first computer line to see the use of IBM's IBM Power microprocessors, POWER and PowerPC based microprocessors. In October 2000, the RS/6000 brand was retired for POWER-based servers and replaced by the pSeries, eServer pSeries. Workstations continued under the RS/6000 brand until 2002, when new POWER-based workstations were released under the IntelliStation POWER brand. History The first RS/6000 models used the Micro Channel architecture, Micro Channel bus, later models used Peripheral Component Interconnect, PCI. Some later models conformed to the PReP and Common Hardware Reference Platform, CHRP standard platforms, which were co-developed with Apple Inc., Apple and Motorola, with Open Firmware. The plan was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
POWER3
The POWER3 is a microprocessor, designed and exclusively manufactured by IBM, that implemented the 64-bit version of the PowerPC instruction set architecture (ISA), including all of the optional instructions of the ISA (at the time) such as instructions present in the POWER2 version of the POWER ISA but not in the PowerPC ISA. It was introduced on 5 October 1998, debuting in the RS/6000 43P Model 260, a high-end graphics workstation.''New IBM POWER3 chip''. The POWER3 was originally supposed to be called the PowerPC 630 but was renamed, probably to differentiate the server-oriented POWER processors it replaced from the more consumer-oriented 32-bit PowerPCs. The POWER3 was the successor of the P2SC derivative of the POWER2 and completed IBM's long-delayed transition from POWER to PowerPC, which was originally scheduled to conclude in 1995. The POWER3 was used in IBM RS/6000 servers and workstations at 200 MHz. It competed with the Digital Equipment Corporation (DEC) Al ...

POWER1
The POWER1 is a Integrated circuit, multi-chip Central processing unit, CPU developed and Semiconductor device fabrication, fabricated by IBM that implemented the IBM POWER Instruction Set Architecture, POWER instruction set, instruction set architecture (ISA). It was originally known as the RISC System/6000 CPU or, when in an abbreviated form, the RS/6000 CPU, before introduction of successors required the original name to be replaced with one that used the same naming scheme (POWER''n'') as its successors in order to differentiate it from the newer designs. History The POWER1 was introduced in 1990, with the introduction of the IBM RS/6000 POWERserver Server (computing), servers and POWERstation workstations, which featured the POWER1 clocked at 20, 25 or 30 MHz. The POWER1 received two upgrades, one in 1991, with the introduction of the POWER1+ and in 1992, with the introduction of POWER1++. These upgraded versions were clocked higher than the original POWER1, made possible ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Byte (magazine)
''Byte'' (stylized as ''BYTE'') was a microcomputer magazine, influential in the late 1970s and throughout the 1980s because of its wide-ranging editorial coverage. "''Byte'' magazine, the leading publication serving the homebrew market ..." ''Byte'' started in 1975, shortly after the first personal computers appeared as kits advertised in the back of electronics magazines. ''Byte'' was published monthly, with an initial yearly subscription price of $10. Whereas many magazines were dedicated to specific systems or the home or business users' perspective, ''Byte'' covered developments in the entire field of "small computers and software", and sometimes other computing fields such as supercomputers and high-reliability computing. Coverage was in-depth with much technical detail, rather than user-oriented. The company was purchased by McGraw-Hill in 1979, a watershed event that led to the rapid purchase of many of the early computer magazines by larger publishers. By this time t ...

Very Large Scale Integration
Very large-scale integration (VLSI) is the process of creating an integrated circuit (IC) by combining millions or billions of MOS transistors onto a single chip. VLSI began in the 1970s when MOS integrated circuit (Metal Oxide Semiconductor) chips were developed and then widely adopted, enabling complex semiconductor and telecommunication technologies. The microprocessor and memory chips are VLSI devices. Before the introduction of VLSI technology, most ICs had a limited set of functions they could perform. An electronic circuit might consist of a CPU, ROM, RAM and other glue logic. VLSI enables IC designers to add all of these into one chip. History Background The history of the transistor dates to the 1920s when several inventors attempted devices that were intended to control current in solid-state diodes and convert them into triodes. Success came after World War II, when the use of silicon and germanium crystals as radar detectors led to improvements in fabrication ...
