Digital Filter

Features

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.

• Eight Filter Cells

• 0MHz to 30MHz Sample Rate

• 9-Bit Coefﬁcients and Signal Data

• 26-Bit Accumulator per Stage

• Filter Lengths Over 1000 Taps

• Expandable Coefficient Size, Data Size and Filter Length

• Decimation by 2, 3 or 4

Applications

• 1-D and 2-D FIR Filters

• Radar/Sonar

The HSP43891 DF can be configured to process expanded

coefficient and word sizes. Multiple DFs can be cascaded

for larger filter lengths without degrading the sample rate or

a single DF can process larger filter lengths at less than

30MHz 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 DF provides for 8-bit unsigned or

9-bit two’s complement 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 / , / or / the input sample rate. These registers also

provide the capability to perform 2-D operations such as

matrix multiplication and NxN spatial

correlations/convolutions for image processing applications.
