Digital Filter

Features

The HSP43881 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 has

a maximum sample rate of 30MHz. The effective multiply

accumulate (mac) rate is 240MHz.

• Eight Filter Cells

• 0MHz to 30MHz Sample Rate

• 8-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

The HSP43881 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 two’s complement

arithmetic, independently selectable for coefﬁcients and

signal data.

• 1-D and 2-D FIR Filters

• Radar/Sonar

• Adaptive Filters

• Echo Cancellation

• Complex Multiply-Add

• Sample Rate Converters
