The sequence of seven LDI instructions in the register-number program with the pipeline execution pattern given on page 540 is fetched and executed. Manually simulate the execution by giving, for each clock cycle, the values in pipeline registers PC, IR, Data A, Data B, Data F, Data I, and in the register file (the latter only when a change in value occurs) for each clock cycle. Assume that all file registers initially contain -1 (all 1s).
