The HSP43881 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 has
a maximum sample rate of 30MHz. The effective multiply
accumulate (mac) rate is 240MHz.
