Fetch-Execute Cycle

The fetch-execute cycle is the fundamental operation of a computer's central processing unit (CPU). It is a two-step process that involves fetching an instruction from memory and then executing that instruction. The fetch-execute cycle is repeated over and over again, until the computer program is complete.

How the Fetch-Execute Cycle Works

The fetch-execute cycle begins when the CPU fetches an instruction from memory. The instruction is stored in a special register called the instruction register. The CPU then decodes the instruction to determine what operation it should perform. Once the instruction has been decoded, the CPU executes the instruction. The result of the instruction is stored in a register or in memory.

The Importance of the Fetch-Execute Cycle

The fetch-execute cycle is essential for the operation of a computer. Without the fetch-execute cycle, the CPU would not be able to execute any instructions. The fetch-execute cycle is also responsible for the speed of a computer. The faster the CPU can fetch and execute instructions, the faster the computer will be.

How to Learn More About the Fetch-Execute Cycle
