SimplePipe is a simulation framework/tool based on SimpleScalar. SimplePipe analyzes the performance effects of alternative task allocations in systems of multiple pipelines where pipeline stages are either processors or dedicated hardware functions. Tasks are defined in terms of sequences of separate C program executions with each sequence representing the functional requirements of a flow. Performance effects associated with alternative assignment of shared memory modules to pipeline stage can also be explored. SimplePipe was motivated by the performance requirements of network processors (NPs) that are configurable into multiple processor pipelines. The assignment of communication flow tasks to pipeline stages, selection of the number of stages, determination of processor cache sizes and the assignment of shared memory modules are important design decisions impacting performance. An assignment study illustrating SimplePipe capabilities is presented.
