Fetch decode
WebAug 7, 2016 · The CPU is now ready to carry out the fetch decode execute cycle. STEP 1. Fetch. The Control Unit sends a signal to the RAM in order to fetch the program and data, which is then stored in one of the CPU’s register. To do so, the CPU makes use of a vital hardware path called the ‘address bus’ along which the program and data travels.
