The fetch-execute cycle is the sequence of actions taken by the microrocessor to perform a task.
This process takes the following phases:
Fetch;
The microprocessor issues an address of an instruction and data to the address bus.
The microprocessor then obtains the data and instructions from the main memory through the data bus and stores them in its temporary memory locations called registers. This process is fetching.
Decode;
The microprocessor interprets and understands the commands in each set of instructions. Relevant areas are prepared for the next action on the instructions. This process is called decoding.
Execute;
When the commands in the instructions and data are performed, it is said to have been executed. The result of this processing is stored in a different register and the cycle is complete.
