Abstract

A computer architecture and programming model for high speed processing over broadband networks are provided. The architecture employs a consistent modular structure, a common computing module and uniform software cells. The common computing module includes a control processor, a plurality of processing units, a plurality of local memories from which the processing units process programs, a direct memory access controller and a shared main memory. A synchronized system and method for the coordinated reading and writing of data to and from the shared main memory by the processing units also are provided. A processing system for processing computer tasks is also provided. A first processor is of a first processor type and a number of second processors are of a second processor type. One of the second processors manages process scheduling of computing tasks by providing tasks to at least one of the first and second processors.
