DynaNP - A Coarse-grain Dataflow Network Processor Architecture with Dynamic Configurable Processing Path

Aimed at the limitation of ILP exploitation and the fixed topology of control-flow NP, a new scheme of coarse-grain dataflow NP architecture - DynaNP is proposed. DynaNP can not only improve the programmability of NP by adopting control-flow structure in each processing element (PE), but also effectively exploit the task-level parallelism by introducing data-flow model into the processing of multiple PEs. A mechanism of dynamic configurable processing path is also provided in DynaNP. Art S-DTPPS algorithm based on dynamic configurable processing path is proposed in DynaNP. The simulation results show that by using this algorithm the load of each PE can be balanced efficiently and the overall throughput of DynaNP will be improved.
