WebLesson 3 The FDE cycle. Curriculum > KS4 > Unit > Lesson. In 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. WebThe 2nd Fetch, Decode and Execute Cycle You will now run through the remaining two cycles of the program. The PC now holds 0001, so you fetch, decode, and execute the instruction at that address. The PC is at 0001, so this is the next instruction to be fetched.
