<architecture, processor> The sequence of actions that a central
processing unit performs to execute each machine code instruction in a program.
At the beginning of each cycle the CPU presents the value of the program counter
on the address bus. The CPU then fetches the instruction from main memory
(possibly via a cache and/or a pipeline) via the data bus into the instruction
From the instruction register, the data forming the instruction is decoded and
passed to the control unit which sends a sequence of control signals to the
relevant function units of the CPU to perform the actions required by the
instruction such as reading values from registers, passing them to the ALU to
add them together and writing the result back to a register.
The program counter is then incremented to address the next instruction and the
cycle is repeated.
The fetch-execute cycle was first proposed by John von Neumann.
