A fetch cycle is the

Steps in the instruction cycle:

• First of all, the opcode is fetched by the microprocessor from a stored memory location.
• Then it is decoded by the microprocessor to find out which operation it needs to perform.
• If an instruction contains data or operand address that is still in the memory, the CPU has to perform a read operation to get the desired data.
• After receiving the data, it performs to execute the operation.

Correct sequence: fetch → decode → read effective address → execute
