Implementation of real time image convolutions in FPGA structures

Jamro E., Wiatr K.

Image Processing & Communications

2001

Vol. 7, no 1-2

55-63

In this paper different architectures for real time image constant coefficients convolutions will be considered. Accordingly, Look-Up Table (LUT) based Multiplication/Convolution, Lut based Distributed Arithmetic Convolution and Multiplierless Convolution (MC) implementations into FPGA structures has been investigated. In a result, the choice between these architectures depends on given coefficients values, however in most cases the MC preferable. Furthermore the change of coeffcient values in real time systems is also considered.
