HSP43881 Description
HSP43881 Data Sheet May 1999 File Number 2758.4 Digital Filter The HSP43881 is a video speed Digital Filter (DF) designed to efficiently implement vector operations such as FIR digital filters. It is prised of eight filter cells cascaded internally and a shift and add output stage, all in a single integrated circuit. Each filter cell contains a 8 x 8-bit multiplier, three decimation registers and a 26-bit accumulator.
