Suppose a MIPS processor uses the simple 5-stage pipeline described in the text, where the stages are instruction fetch, instruction decode and operand fetch, execute and calculate address, memory access, and register write. Suppose further that • There is a single memory for both instruction and data, which can only support one read or write each cycle. • There is no “forwarding” in the pipeline. Thus, if an instruction B relies on a value written into a register by an...
