ABSTRACT

The DARPA-sponsored DSP-3 Multiprocessor Project at AT&T has produced a multi-GFLOP machine applicable to a variety of signal processing and pattern recognition problems. Software development for the DSP-3 is done primarily on the SUN 3 workstation and then downloaded to the real-time host and the multiprocessor array. A complete set of tools to develop, compile, load, and debug software for both the 68030 host and DSP 32C array is provided to the user. The DSP-3 multiprocessor array has been implemented using a conventional triple-height VME approach. The VME subsystem includes a single-board 68030 processor with a real-time operating system, Ethernet interface to the software development host, bulk random access memory (RAM), and a hard disk. The host processor in the DSP-3 is a VME-based real-time processor. It is a 68030-based single-board computer with 4 Mbytes of RAM and a small computer system interface interface for a hard disk.
