Abstract : A 13th order FIR filter for digital image processing is implemented in microcode using the Am29203 bit-slice evaluation board of ADVANCED MICRO DEVICES. To meet this requirement, the filter is first implementations are used for timing comparisons. Although non-optimal bit-slice devices are used on evaluation board, a time of 11 microseconds achieved in the Fortran implementation. Theoretical estimates of 2.65 microseconds and 0.78 microseconds are obtained for high speed Am2900 bit-slice devices and VITESSE'S Gallium Arsenide bit-slice devices respectively. It is shown that, although the initial learning period for bit-slice devices implement a simple filter design in minimal time with significant results in time savings.
