The HSP43891/883 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 9 x 9 two’s
complement 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 HSP43891/883 has a maximum sample rate of
25.6MHz. The effective multiply-accumulate (mac) rate is
204MHz.
