Description
Summary:We have integrated an image processing system built around PADDI-2, a custom 48 node MIMD parallel DSP. The system includes image processing algorithms, a graphical SFG tool, a simulator, routing tools, compilers, hardware configuration and debugging tools, application development libraries, and software implementations for hardware verification. The system board,connected to a SPARCstation via a custom Sbus controller, contains 384 processors in 8 VLSI chips. The software environment supports a multiprocessor system under development (VGI-1). The software tools and libraries are modular, with implementation dependencies isolated in layered encapsulations.
