Reconfigurable FIR filter using CSD coefficient representation |
摘要 |
The present invention is directed to a reconfigurable finite impulse response (FIR) filter that processes data tap values with canonical sign digit (CSD) coefficients. The FIR filter according to the present invention includes a shift group associated with at least one of the data tap values and at least one of the CSD coefficients. Each shift group includes a plurality of parallel paths. Each parallel path shifts the data tap value according to a bit pair of the coefficient to produce a weighted product. An adder is also included that combines the weighted products from each of the shift groups.
