HSP43481

Digital Filter

September 1997

Features

• Four Filter Cells

• 0MHz to 30MHz Sample Rate

• 8-Bit Coefficients and Signal Data

• 26-Bit Accumulator per Stage

• Filter Lengths Up to 1032 Tap

Description

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 dec-

imation 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 multiply-

accumulate (MAC) rate is 120MHz.

• Expandable Coefficient Size, Data Size and Filter

Length

• Decimation by 2, 3 or 4

The HSP43481 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 30MHz with multiple passes. The architecture per-

mits processing filter lengths of over 1000 taps with the guar-

antee of no overflows. In practice, most filter coefficients are

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

HSP43481 provides for unsigned or two’s complement arith-

metic, independently selectable for coefficients and signal

data.

Applications

• 1-D and 2-D FIR Filters

• Radar/Sonar

• Adaptive Filters

• Echo Cancellation

• Complex Multiply-Add

• Sample Rate Converters

Ordering Information

Each DF filter cell contains three resampling or decimation

registers which permit output sample rate reduction at rates of

¹/₂, ¹/₃or ¹/₄the input sample rate. These registers also pro-

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

spatial correlations/convolutions for image processing appli-

cations.
