This paper presents new hybrid multiplierless finite impulse response (FIR) architecture based on New Distributed Arithmetic (NEDA). The hybrid structure is a trade off between direct form and transposed direct form that results in a reduction of the critical path and the size of the delays elements as well as the fan-out. While the multiplications involved in the hybrid structure are replaced by a butterfly adder tree. Compared with previous methods, our proposed architecture achieves an average of 20% less additions. Moreover, the design method is simple and achieves better results than previous methods.

-Hybrid form FIR filters have been shown to provide a trade-off between the direct form and transposed direct form FIR filters resulting in a low power implementation. However, the use of multiple constant multiplication (MCM) techniques is less advantageous as it results in several MCM blocks. In this work a method of implementing low-complexity hybrid form FIR filters using matrix multiple constant multiplication blocks is proposed. The utilized filter structure can be seen as a polyphase decomposition with common delay lines for the subfilters.
