Implementation image data convolutions operations in FPGA reconfigurable structures for real-time vision systems

Abstract

In this paper different architectures for real time image constant coefficients convolutions are considered. Accordingly, look-up-table (LUT) based multiplication/convolution, LUT based distributed arithmetic (DA) convolution and multiplierless convolution (MC) implementations into FPGA structures has been investigated. In one result, the choice between these architectures depends on given coefficients values, however in most cases the MC preferable. Furthermore the change of coefficient values in real-time systems is also considered. This work is a contribution to worldwide intense research on developing reconfigurable and user dedicated custom computing machines (CCM).
