Describe the fetch-execute cycle
WebIn this lesson, the learners’ knowledge about the components that make up the CPU and main memory will be furthered with the introduction of the fetch-decode-execute cycle (FDE). Learners will be able to connect the parts of the CPU to their role in executing instructions visually. Learning objectives WebEach cycle, the CPU fetches an instruction, decodes it to find out what to do and then carries out the instruction ( executes it). This process happens continuously whilst the computer is on and uses a number of registers: PC - Program Counter MAR - Memory Address Register MDR - Memory Data Register CIR - Current Instruction Register
