The HSP43881/883 is a video speed Digital Filter (DF)
designed to efficiently implement vector operations such as
FIR digital filters. It is comprised 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 HSP43881/883 has a maximum sample rate of
25.6MHz. The effective multiply accumulate (mac) rate is
204MHz.
