      • Buses for data transfer (data, address, control)

    Key Technical Parameters

    • Clock Speed (measured in Hertz): The rate at which instructions are executed (higher the better).
    • Number of Cores: Multiple CPUs in a single chip for faster processing.
    • Cache Size: Amount of high-speed integrated memory for faster access to frequently used data.
    • Instruction Set Architecture (ISA): Defines the instructions the CPU can understand.
    • Manufacturing Process: Transistor size affects the number of transistors on a chip, smaller the better for performance.
    • Power Consumption: Measured in watts, indicates the amount of power a microprocessor consumes.
