HSP43881 Datasheet | Intersil

Data Sheet May 1999 File Number 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. The output stage contains an additional 26-bit accumulator which can add the contents of any filter cell accumulator to the output stage accumulator shifted right by 8 bits. The HSP43881 has a maximum sample rate of 30MHz. The effective multiply accumulate (mac) rate is...
