Abstract
A repeatable finite anti infinite impulse response integrated circuit structure has a plurality of filter units programmably interconnected, with each filter unit having a pair of repeatable cells. Each cell has a coefficient stage for receiving a filter coefficient, a mixer stage for multiplying a selected one of a plurality of input signals by the filter coefficient, an accumulator stage for selectively delaying an input accumulation signal, and a summation stage for adding the input accumulation signal to the weighted signal to produce an output accumulation signal. With appropriate programming many desired finite/infinite impulse response filter configurations may be achieved.
