US Patent:

48211745, Apr 11, 1989

Filed:

Jun 21, 1988

Appl. No.:

7/211126

Inventors:

Richard F. Webb - Baltimore MD
Charles W. Brooks - Wayland MA

Assignee:

Westinghouse Electric Corp. - Pittsburgh PA

International Classification:

G06F 1300

US Classification:

364200

Abstract:

A signal processing system that includes a ring bus; a multiplicity of system modules, each coupled to the ring bus and operative to receive and transfer blocks of data words over the ring bus; and a bus control module coupled to the ring bus and operative to support simultaneous data transfers between specified pairs of system modules in accordance with concurrent execution of multiple programs of data transfer instructions. In an alternate embodiment, the signal processing system may include a plurality of ring buses wherein each system module is coupled to all of the ring buses and operative to receive and transfer blocks of data words over any one of the ring buses. In addition, the bus control module is also coupled to all of the ring buses and operative to support simultaneous data transfers between specified pairs of system modules over all of the ring buses. Moreover, each ring bus may comprise individual bus segments for system module to system module coupling about the ring.

Abstract:

The processor is optimized for high-speed processing of large vectors, to fully utilize VHSIC technology, and to implement a signal processor having the highest possible throughput per volume while maintaining flexibility. It includes a 25 MHz embedded 1750A computer for performing control function scalar operations and set-up of vector signal processing instructions to be performed by a vector processing unit. The 40 MHz vector processing unit (VPU) performs high speed processing of real and complex vectors. The VPU's control portion provides an interface and status to the embedded 1750A computer. It also provides the control necessary for vector processing to occur concurrently with 1750A execution and concurrent with I/O of vector data.
