Use the classic RISC five stage integer pipeline and assume all memory accesses take 1 clock cycle.

Show the timing of this instruction sequence for the basic 5-stage RISC pipeline, but without any forwarding or bypassing hardware. Furthermore, assume that a register write at the WB stage happens in the first half of the clock cycle, while a register read at the ID stage happens in the second half of the clock cycle. This means that a write at WB stage can forward value through the register file to a read at the ID stage (trivia: MIPS R2000/R3000 has such a feature).

Use 'F', 'D', 'X', 'M', 'W' for stages, -' for stall, '=' for indicating delayed fetching due to waiting for branch resolution, and 'b' for all other blanks.

Use the following code fragment from Question 1: Use the classic RISC five stage integer pipeline and assume all memory accesses take 1 clock cycle. Show the timing of this instruction sequence for the basic 5-stage RISC pipeline, but without any forwarding or bypassing hardware. Furthermore, assume that a register write at the WB stage happens in the first half of the clock cycle, while a register read at the ID stage happens in the second half of the clock cycle. This means that a write at WB stage can "forward" value through the register file to a read at the ID stage (trivia: MIPS R2000/R3000 has such a feature). Use ' F ', 'D', 'X, 'M', 'W' for stages, -' for stall, '=' for indicating delayed fetching due to waiting for branch resolution, and 'b' for all other blanks.
