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 ...
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.
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.

Minimal instruction set computer ( MISC) is a central processing unit (CPU) architecture, usually in the form of a microprocessor, with a very small number of basic operations and corresponding opcodes, together forming an instruction set. Such sets are commonly stack-based rather than register-based to reduce the size of operand specifiers.
t. e. 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.
A one-instruction set computer (OISC), sometimes referred to as an ultimate reduced instruction set computer (URISC), is an abstract machine that uses only one instruction – obviating the need for a machine language opcode.
