RISC-V [b] (pronounced "risk-five" [2]: 1 ) is an open standard instruction set architecture (ISA) based on established reduced instruction set computer (RISC) principles. . The project began in 2010 at the University of California, Berkeley, transferred to the RISC-V Foundation in 2015, and on to RISC-V International, a Swiss non-profit entity, in November 20
In computer science, an instruction set architecture (ISA) is an abstract model that generally defines how software controls the CPU in a computer or a family of computers. [1] A device or program that executes instructions described by that ISA, such as a central processing unit (CPU), is called an implementation of that ISA.
An instruction set architecture (ISA) is an abstract model of a computer, also referred to as computer architecture.A realization of an ISA is called an implementation.An ISA permits multiple implementations that may vary in performance, physical size, and monetary cost (among other things); because the ISA serves as the interface between software and hardware.
The Sun Microsystems UltraSPARC processor is a type of RISC microprocessor.. In electronics and computer science, a reduced instruction set computer (RISC) is a computer architecture designed to simplify the individual instructions given to the computer to accomplish tasks.
Processors implement a set of these categories as required for their task. Different classes of processors are required to implement certain categories, for example a server-class processor includes the categories: Base, Server, Floating-Point, 64-Bit, etc. All processors implement the Base category. Power ISA is a RISC load/store architecture.
Alpha (original name Alpha AXP) is a 64-bit reduced instruction set computer (RISC) instruction set architecture (ISA) developed by Digital Equipment Corporation (DEC). Alpha was designed to replace 32-bit VAX complex instruction set computers (CISC) and to be a highly competitive RISC processor for Unix workstations and similar markets.
The Precision Architecture is the result of what was known inside Hewlett-Packard as the Spectrum program. [6] HP planned to use Spectrum to move all of their non-PC compatible machines to a single RISC CPU family. In early 1982, work on the Precision Architecture began at HP Laboratories, defining the instruction set and virtual memory system.
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. [1] 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 ...
