Q. Show Two Way Pipelined Timing?
Figure below demonstrates a simple pipelining scheme in which F and E stages of two different instructions are performed concurrently. This scheme increases the execution rate of sequential scheme.
Figure: Two Way Pipelined Timing
Please note that pipeline above isn't running at its full capacity. This is ought to the following problems:
This pipeline can simply be improved by allowing two memory accesses at a time.
So modified pipeline will be:
Pipeline may suffer due to data dependencies and branch instructions penalties. A good pipeline has equivalent phases.
