RAW Dependency, Latencies

Define-use Latency is the time delay after decoding and issue of an instruction until the result becomes available for a subsequent RAW dependent instruction. add r1, r2,r3 add r5, r1, r6 <- define-use dependency Usually one cycle for simple instructions.

Define-use Delay of an instruction is the time a subsequent RAW-dependent instruction has to be stalled in the pipeline. It is one less cycle than the define-use latency.
