Two questions, submit as "quiz24". Due 7:45pm 10/24/2007.
1.
The single cycle datapath described in P&H 5.1 must have separate instruction and data
memories because (choose one):
the format of data is different from the format of instructions in MIPS.
having separate memories is less expensive.
the processor operates, in one cycle, one both a word of data and an instruction, meaning
it cannot use a single ported (one set of read/write wires) memory.
Please explain your answer very briefly.
2.
True or False: Because the register file is both written and read on each clock cycle (for
arithmetic instructions) any MIPS datapath using edge-triggered flip-flops, also known as registers
in lecture, must have more than one copy of the register file. Please explain your answer very briefly.
