Abstract :
A general decimation technique to optimise (i.e. minimise) data transfer in the implementation of one-dimensional and two-dimensional FIR filters is presented. The approach is particularly significant when the implementation consists of multiplier arrays connected to a micro/minicomputer. The scheme significantly improves processing speed. For 100 × 100 2-dimensional array, the required data transfer is reduced from 10000 to 200.
