ELSA-a wafer scale image processing system

Describes the architecture of the ELSA Processor, a massively parallel SIMD/MSIMD machine implemented in wafer scale technology, and its capability to implement many algorithms in image processing, pattern recognition, signal processing, etc. The ELSA Processor contains 2304 bit serial processing elements (PEs) configured in a two dimensional array. The wafer employs a 1.2 μm double metal CMOS process and will operate at a clock speed of up to 20 MHz. For eight bit data, additions can be carried out at about 5 billion per second
