Simplifies control of deep pipeline because elements in vector are independent 17 V 1 V 2 V 3 V3 <- v1 * v2 Six stage multiply pipeline Slide credit: Krste Asanovic . WebbPipeline terminology The pipeline depth is the number of stages—in this case, five. In the first four cycles here, the pipeline is filling, since there are unused functional units. In cycle 5, the pipeline is full. Five instructions are being executed simultaneously, so all hardware units are in use. In cycles 6-9, the pipeline is emptying. WebbKäsgen, P.
