Abstract :
Architecture and custom circuit design of a multiprocessor chip for digital signal processing (DSP) and digital image processing have been developed. Mappings of digital image processing and neural network algorithms are presented. The processor design supports the execution of key signal processing functions. The processing elements can be connected in a 1D linear ring or 2D systolic mesh array. A microprogrammed controller is used to enhance the processor performance. Each processor occupies 4.1 mm2 by using an industrial-scale 0.5-μm CMOS technology from TRW Inc. Sixty-four processing elements can be implemented in a 1.5-cm×1.8-cm chip and achieve 2.56 billion calculations per second
