Title: Recursive processor employing redundant number arithmetic
Inventor: KNOWLES SIMON CHRISTIAN
IPC: G06F7/48
Filed: 1993-09-22
Abstract: A processor suitable for recursive computations incorporates multiplier cells P connected to form rows and columns. Each row is arranged to multiply by a coefficient 1. It begins with accumulator cells Q, R, T and continues with cells arranged to multiply by individual coefficient digits and disposed in descending order of digit significance. Multiplier cells within a column are arranged in ascending order of multiplier digit significance. The accumulator cells operate in accordance with signed digit number representation arithmetic involving digit redundancy. The cells generate sum and transfer digits for output down columns and along rows respectively to neighbouring cells, in the direction of increasing digit significance in the case of transfer digits. The cell arithmetic employed makes it possible to compute results most significant digit first. Each result digits yn-1 is recycled when formed to provide a multiplicand digit input or all multiplier cells of a respective row according to result digit significance. Two's-complement inputs are handled by associating the first-row multiplier cell of highest significance with a negatively-weighted coefficient/input-term product digit and associating other multiplier cells with positively-weighted coefficient/input-term product digits. The processor may also be arranged to add successive non-recursive input terms un to multiplier products, to provide a first order infinite impulse response (IIR) filter. Two cascaded processors may provide a second order IIR filter (Fig 6). <IMAGE>
