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.
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
ARM (stylised in lowercase as arm, formerly an acronym for Advanced RISC Machines and originally Acorn RISC Machine) is a family of RISC instruction set architectures (ISAs) for computer processors. Arm Holdings develops the ISAs and licenses them to other companies, who build the physical devices that use the instruction set.
Classic RISC pipelines avoided these hazards by replicating hardware. In particular, branch instructions could have used the ALU to compute the target address of the branch. If the ALU were used in the decode stage for that purpose, an ALU instruction followed by a branch would have seen both instructions attempt to use the ALU simultaneously.
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.
SPARC (Scalable Processor ARChitecture) is a reduced instruction set computer (RISC) instruction set architecture originally developed by Sun Microsystems. [ 1 ] [ 2 ] Its design was strongly influenced by the experimental Berkeley RISC system developed in the early 1980s.
The U.S. Department of Commerce is reviewing the national security implications of China's work in open-source RISC-V chip technology, according to a letter sent to U.S. lawmakers. RISC-V ...
Building on UC Berkeley RISC and Sun compiler and operating system developments, SPARC architecture was highly adaptable to evolving semiconductor, software, and system technology and user needs. The architecture delivered the highest performance, scalable workstations and servers, for engineering, business, Internet, and cloud computing uses.
