In this paper, a special purpose, fully parallel and pipelined, CORDIC processor that performs Given's Rotations is presented. The Given's Rotation (GR) processor is based on modifications of the original CORDIC circular rotation algorithm, so that the decoupling between the word length of the input/output signals and the resolution of the angle, to be accomplished. Exploiting this feature and also using the CORDIC representation of the rotation angle a significant reduction of the chip area is achieved. A methodology for the determination of the architectural parameters according to the application requirements is presented, as well as the VLSI implementation of a specific GR processor for high fidelity audio applications. The implemented processor performs 4 × 10 7 vector rotations per second. In the last part of this paper, the design of a high throughput digital equalizer based on the GR processor is presented which processes simultaneously 1,000 independent filters. |
