Consider a standard 5-stage MIPS pipeline of the type discussed
during the class sessions: IF-
ID-EX-M-WB.
Assume that forwarding is not implemented and only the hazard
detection and stall logic is
implemented so that all data dependencies are handled by having the
pipeline stall until the
register fetch will result in the correct data being fetched.
Furthermore, assume that the memory is written/updated in the first
half of the clock cycle
(i.e. on the rising edge of the clock) and...
