Definition

Noun (Computer Science): A design philosophy and type of computer architecture characterized by a small, highly optimized set of simple instructions. This contrasts with architectures using a larger set of more complex instructions.

Usage

The term is used to describe a fundamental approach to processor design. * The new processor's efficiency stems from its use of reduced instruction set computing. * Reduced instruction set computing often allows for faster execution of individual instructions.

Advanced Usage

• The acronym RISC is the standard and most common way to refer to this concept.
  • RISC architectures are prevalent in mobile devices and embedded systems.
• It is frequently contrasted with CISC (Complex Instruction Set Computing).
  • The debate between RISC and CISC design philosophies has shaped modern computing.

Variants and Related Words

• RISC (noun/acronym): The standard abbreviated form of "reduced instruction set computing."
• RISC processor (noun phrase): A central processing unit (CPU) designed based on RISC principles.
• Reduced instruction set computer (noun phrase): A computer system built around a RISC processor.

Synonyms

• RISC architecture (noun phrase)

Antonyms

• Complex instruction set computing (CISC) (noun phrase): A computer architecture design with a large set of complex, multi-step instructions.
