1. (20 pts, 10 each) Consider the RISC computer (byte-addressable with 32-bit words) with a 5-stage pipelined data path, as discussed in Lecture #22. R3 and R4 initially contain 50 and 65, respectively. All the numbers are in decimal. What are the contents (in decimal) of RA, RB, RZ, RM, RY, and R4 after stages 2,3, 4, 5 for the following two instructions, respectively? Fill out the below table for each case. Use X for any unknown values. Hint: You can find the sequence of actions of the two instructions in Section 5.4 of the textbook. Subtract has the same sequence with Add. (a) Subtract R4, R3, #200 (b) Store R4, 200(R3) Stage 2Stage 3Stage 4Stage 5 RA RB RZ RM RY R4 1.
