Reduced Instruction Set Computer ist eine Designphilosophie für Computerprozessoren. Der Begriff wurde 1980 von David A. Patterson und Carlo H. Séquin geprägt. Das Designziel war der Verzicht auf einen komplexen, für die Assemblerprogrammierung komfortablen Befehlssatz hin zu einfach zu dekodierenden und schnell auszuführenden ...
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. Compared to the instructions given to a complex instruction set computer (CISC), a RISC computer might require more instructions (more ...
RISC-V (pronounced "risk-five": 1 ) is an open standard instruction set architecture (ISA) based on established reduced instruction set computer (RISC) principles. Unlike most other ISA designs, RISC-V is provided under royalty-free open-source licenses.
A reduced instruction set computer (RISC) simplifies the processor by efficiently implementing only the instructions that are frequently used in programs, while the less common operations are implemented as subroutines, having their resulting additional processor execution time offset by infrequent use.
A reduced instruction set computing ( acronym RISC pronounced risk ), represents a CPU design method to simplify instructions which "do less" but provide higher performance by making instructions execute very fast. RISC was developed as an alternative to what is now known as CISC.
The Berkeley project became known as the Reduced Instruction Set Computer (RISC), and the result was the development of single-chip microprocessors. The technology — novel, even counter-intuitive at the time — was led by Patterson and fellow computer science professor Carlo Séquin.
Learn how IBM researchers led by John Cocke developed RISC, a microprocessor architecture that simplified instructions and increased speed. Explore how RISC influenced computing from PCs and mobile devices to gaming and space travel.
