Author Affiliations +
Basic digital beamforming architectures will be reviewed. Architectures will be analyzed for spectral characterization and hardware considerations which consist of A/D converter requirements, data storage strategies, and computational complexity. The goals of parallel processing will be illustrated along with the basic forms of parallel computation.Granularity issues which measure the ratio of the amount of computation done in a parallel task to the amount of inter-processor communication will be illustrated. Software systems will be described that allow the beamforming architectures to be modeled and tested for data throughput requirements as well as computational loading with respect to application specific concurrent architectures. One specific structure, MPI, will be described and used to illustrate how parallel processing architectures may be synthesized and tested.
