The Hughes Data Flow Multiprocessor (HDFM) is a proposed high performance, fault tolerant, high level language programmable processor targeted for embedded signal and d•t• processing applications.Based on the data flow principle, the HDFM can exploit the inherent parallelism in applications without explicit programmer identification of independent tasks, thus freeing the programmer from the often difficult job of creating parallel tasks and assigning these to different processors.The d•t• flow architecture consists of many processing elements (PEs) connected by • three dimensional bussed-cube packet routing network.The PEs are designed for VLSI implementation to provide large throughput, real-time processing.The modular, extensible nature of the computer allows for • wide number of PEs to meet a range of throughput and reliability requirements.Simulation results have domonstrated high performance operation and high level language programmability.
