WebThis process is known as the fetch-decode-execute cycle. The cycle begins when an instruction is transferred from memory to the IR along the data bus. In the IR, the unique bit patterns that make up the machine-language are extracted and sent to the Decoder. WebFetch. The first step is retrieving, or fetching, an instruction from program memory. The CPU reads an address of where the instruction to be fetched is stored. The program counter then updates—the CPU now has the address of the next instruction it will need to fetch. Decode. Once the CPU fetches an instruction, it needs to decode it.
