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
RISC-V assembly language is a low-level programming language that is used to produce object code for the RISC-V class of processors. Assembly languages are closely tied to the architecture's machine code instructions, allowing for precise control over hardware. Assemblers include GNU Assembler and LLVM.
The varieties of RISC processor design include the ARC processor, the DEC Alpha, the AMD Am29000, the ARM architecture, the Atmel AVR, Blackfin, Intel i860, Intel i960, LoongArch, Motorola 88000, the MIPS architecture, PA-RISC, Power ISA, RISC-V, SuperH, and SPARC. RISC processors are used in supercomputers, such as the Fugaku. [8]
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.
CO-Design Application-Specific Instruction-set Processor) is a processor technology company enabling system-on-chip developers to differentiate their products. The company specializes in RISC-V processor technologies and offers Codasip Studio, a tool suite for processor design using the CodAL architecture description language.
The processor design is free of any royalty and is open-source licensed under the modified BSD License. [5] E-class and C-class cores are both implemented in Bluespec SystemVerilog (BSV) language, a Haskell dialect. [2] The Shakti project aims to build 6 variants of processors based on the RISC-V ISA.
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 ...
SiFive, Inc. is an American fabless semiconductor company and provider of commercial RISC-V processors and silicon chips based on the RISC-V instruction set architecture (ISA). [6] Its products include cores, SoCs, IPs, and development boards. [7] SiFive is one of the first companies to produce a chip that implements the RISC-V ISA. [8]
