(computer science) a kind of computer architecture that has a relatively small set of computer instructions that it can perform
A computer that uses a small, simplified set of frequently-used instructions for rapid execution.
Newest generation of microprocessors which implement instructions that are reduced from a complex instruction format (CISC). These instructions are typically executed directly on the hardware state machine, rather than 3microcoded2 as in CISC architectures. Therefore, many RISC instructions can execute in a single clock cycle. However, it may take multiple RISC instructions to complete the same function as one CISC instruction.
A philosophy of instruction set design where a small number of simple, fast instructions are implemented rather than a larger number of slower, more complex instructions.
A microprocessor in which all machine instructions are uniformly formatted and are processed through the same steps See also: PowerPC microprocessor
A class of computer designs that uses a relatively small set of frequently used instructions that execute in one cycle.
The reduced instruction set computer, or RISC, is a CPU design philosophy that favors a reduced instruction set as well as a simpler set of instructions. The most common RISC microprocessors are Alpha, ARC, ARM, AVR, MIPS, PA-RISC, PIC, Power Architecture, and SPARC.
