A parallel 2 Gops/s image convolution processor with low I/O bandwidth

Abstract

A customized image processor for real time convolution of an image has been developed. Image convolution requires an extensive amount of calculation capacity and I/O communication which is hard to sustain with standard processors in real time. Therefore, a customized processor has been designed with a tailored architecture. The processors have a total sustained calculation capacity of >2G arithmetic operations/s at 20 MHz clock frequency, surpassing that of TMS320C80 for this application due to the tailored architecture.
