ABSTRACT:
A structure for implementing a plurality of independent filters, such as finite impulse response filters, in an efficient manner. Coefficient and data operands associated with each of the independent filters are stored in a predetermined order in a storage device and selectively coupled to an arithmetic unit for processing in a predetermined manner. Calculations for each filter are successively made and selectively stored. Although independent filters exist, processing circuitry is multiplexed and shared to substantially minimize associated control circuitry.
