Definition

Noun: - (Computer Science) A kind of computer architecture: RISC is an acronym for Reduced Instruction Set Computer. It refers to a microprocessor design philosophy that uses a small, highly optimized set of simple instructions, rather than a more complex set of varied instructions.

Usage

The term "RISC" is used as a noun to describe a specific class of processor architecture or the design philosophy itself. It is often contrasted with CISC (Complex Instruction Set Computer).

Examples

• Noun:
  • Modern smartphones often use processors based on RISC principles.
  • The debate between RISC and CISC architectures was a major topic in computer design.

Advanced Usage

• As a modifier: "RISC" is frequently used as an adjective to describe other nouns related to this architecture.
  • RISC processor
  • RISC design
  • RISC architecture

Variants and Related Words

• RISC-based (adj): Built upon or using RISC principles.
  • The device features a RISC-based CPU.
• CISC (noun): Acronym for Complex Instruction Set Computer, the contrasting architecture to RISC.

Synonyms

• Reduced Instruction Set Computer: The full form of the acronym.
• Load-store architecture: A common characteristic of RISC designs, where operations are performed on processor registers and memory is accessed only through specific load and store instructions.

Related Phrases

• RISC-V: An open-source instruction set architecture (ISA) based on RISC principles.
  • RISC-V is gaining popularity for its open-standard design.
