A 20MHz 32b pipelined CMOS image processor

A 32b image processor with writable control stores that can process a 1024-point complex FFT in 1ms, has been developed. This paper will report on features which include fabrication in 1.2μm N-well CMOS, use of double layer metal technology and the integration of 170K transistors. Dissipation is 750mw at 5V.
