The HSP43481 is a video-speed Digital Filter (DF) designed
to efficiently implement vector operations such as FIR digital
filters. It is comprised of four filter cells cascaded internally
and a shift-and-add output stage, all in a single integrated
circuit. Each filter cell contains an 8 x 8 multiplier, three decimation
registers and a 26-bit accumulator which can add
the contents of any filter cell accumulator to the output stage
accumulator shifted right by eight-bits. The HSP43481 has a
maximum sample rate of 30MHz. The effective multiplyaccumulate
(MAC) rate is 120MHz.
