Repeat Problem 10-6 for the instruction SIU R2 R2 635A with R2 containing 0A5FBC2B.

Problem 10-6

For the RISC CPU in Figure 10-8, manually simulate, in hexadecimal, the processing of the instruction ADI R1 R16 2F01 located in PC = 10F.
Assume that R16 contains 0000001F. Show the contents of each of the pipeline platforms and of the register file (the latter only when a change in value occurs) for each of the clock cycles.
