Consider the MIPS instruction sequence shown in Figure2 (where RO, R1, R2, R3, R4, and R6 are 32-bit
general-purpose registers): (a). Identify the instructions that are supported by the write-back (WB)
stage of the system. (b). What is the memory address of the store instruction at line 2 (assume that R2
and R3 are initialized with 0x00000008, and 0x00000005 respectively)? Need a short quick answer.
