Digital Filter

Features

The HSP43881/883 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 HSP43881/883 has a maximum sample rate of

25.6MHz. The effective multiply accumulate (mac) rate is

204MHz.

• This Circuit is Processed in Accordance to MIL-STD-883

and is Fully Conformant Under the Provisions of

Paragraph 1.2.1.

• 0MHz to 25.6MHz Sample Rate

• Eight Filter Cells

• 8-Bit Coefficients and Signal Data

• Low Power CMOS Operation

• I

160mA Maximum at 20MHz

• 26-Bit Accumulator Per Stage

• Filter Lengths Up to 1032 Taps

The HSP43881/883 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 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 DF provides for 8-bit unsigned or two’s complement

arithmetic, independently selectable for coefficients and

signal data.

• Expandable Coefficient Size, Data Size and Filter Length

• Decimation by 2, 3 or 4

Applications

• 1-D and 2-D FIR Filters

• Radar/Sonar

• Adaptive Filters

• Echo Cancellation

• Complex Multiply-Add

• Sample Rate Converters

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

Ordering Information

provide the capability to perform 2-D operations such as

matrix multiplication and N x N spatial correlations/convolutions

for image processing applications.
