摘要：

In this work an FIR filter architecture requiring half the number of multiplications compared to a direct is proposed. The proposed filter architecture is indeon coefficient selection and is therefore suitable for the of FIR filters where the filter impulse response is not anti-symmetric. The filter architecture is based on a product scheme due to Winograd, which to the best of the knowledge has not been applied to FIR filters before. A of different realizations for sequential and two-parallel versions are derived.
