Definition
  1. Noun:
    • (Computer Science) The process of carrying out an instruction by a computer: This term refers to the specific action performed by a computer's central processing unit (CPU) when it follows a single command from a program. It is a fundamental step in the fetch-decode-execute cycle.
Usage Examples
  • Noun:
    • The speed of instruction execution directly affects a processor's overall performance.
    • Modern CPUs use pipelining to overlap the fetch, decode, and instruction execution stages.
    • A runtime error occurs during the instruction execution if the data is invalid.
Advanced Usage

  • "cycle of instruction execution": Refers to the complete sequence of fetching, decoding, and executing a single instruction.

    • Optimizing the cycle of instruction execution is a key goal in microprocessor design.

  • "out-of-order instruction execution": A performance feature where a CPU executes instructions in an order different from the program to avoid delays.

    • Out-of-order instruction execution allows the processor to make better use of its resources.
Variants and Related Words

  • Execute (verb): To carry out an instruction or program.

    • The CPU will execute the next command.

  • Instruction (noun): A single operation command for a computer.

    • The ADD instruction tells the processor to add two numbers.

  • Instruction cycle (noun): The complete process of fetching, decoding, and executing an instruction.

    • The instruction cycle is repeated billions of times per second.
Synonyms
  • Command execution
  • Instruction processing
Related Phrases

  • Instruction execution unit: The part of a processor responsible for carrying out operations.

    • The arithmetic logic unit (ALU) is a core component of the instruction execution unit.

  • Instruction execution time: The time required to complete a single instruction.

    • Reducing instruction execution time was a major breakthrough.
