Design of a 20 MHz 64-tap transversal filter

The authors describe the architecture and design of a high-speed CMOS VLSI filter processor. The internal architecture of the design is pipelined to achieve a sustained 20-MHz data throughput rate. This translates into an effective computational rate of 1.2 billion multiplications (and a similar number of additions) per second. The chip is reconfigurable for one- and two-dimensional filtering, the total device count is 240000 transistors, and the die size is 1.4 cm*1.4 cm. Tap design, data-flow organization, and clock distribution are discussed.<>
