1.1.1a - processor structure + function (y12) Flashcards
What does CPU stand for?
Central Processing Unit
What is the primary function of the CPU?
To process data and instructions by constantly repeating the fetch-execute cycle.
Name the four main components of the CPU.
Control Unit, Arithmetic Logic Unit (ALU), Registers, Cache Memory
What is the role of the Control Unit in the CPU?
It sends control signals to direct the operation of the CPU and decodes instructions as part of the fetch-execute cycle.
Describe the function of the Arithmetic Logic Unit (ALU).
It performs simple calculations and logical operations.
What are registers in the context of the CPU?
Temporary storage spaces for one instruction or address used during the fetch-execute cycle.
Explain the purpose of cache memory in the CPU.
It temporarily stores data that is frequently accessed, speeding up processing.
What is Von Neumann architecture?
A computer design model where both program instructions and data are stored in the same memory (RAM) and in the same format (binary).
Who is Von Neumann architecture named after?
Mathematician John Von Neumann.
How are instructions and data differentiated in Von Neumann architecture?
Instructions are actions to perform (opcode), and data are the values to be used (operand).
