Description

The HSP43481/883 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 out-

put stage accumulator shifted right by eight-bits. The

HSP43481/883 has a maximum sample rate of 25.6MHz.

The effective multiply-accumulate (MAC) rate is 102MHz.

The HSP43481/883 can be configured to process expanded

coefficient and word sizes. Multiple devices can be cas-

caded for larger filter lengths without degrading the sample

rate or a single device can process larger filter lengths at

less than 25.6MHz with multiple passes. The architecture

permits processing filter lengths of over 1000 taps with the

guarantee of no overflows. In practice, most filter coefficients

are less than 1.0, making even larger filter lengths possible.

The HSP43481/883 provides for unsigned or two’s comple-

ment arithmetic, independently selectable for coefficients

and signal data.

Each DF filter cell contains three resampling or decimation

registers which permit output sample rate reduction at rates of

vide the capability to perform 2-D operations such as N x N

spatial correlations/convolutions for image processing appli-

cations.
