Abstract
A CAD tool is presented for producing very high through- put IIR filters. The architecture is a cascade of blocked* pipelined, second-order sections. Because it is application-specific, it is a very high level CAD tool. An engineer only needs to specify 1) the word size w; 2) the block size B; and 3) each second-order section’s coefficients. Using this information, the CAD tool will generate CIF files for a filter system that, operating at 10 MHz, can process 5 B/w million samples/s. Our purpose is to illustrate the benefits of applying both bit-level array architecture and application-specific CAD to the problem of IIR filtering. The resulting CAD system reduces the costs of very high throughput IIR filters with respect to design, fabrication, and operation. © 1988 IEEE
