The HSP43891 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 9x9
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 has a maximum
sample rate of 30MHz. The effective multiply-accumulate
(mac) rate is 240MHz.
