Abstract EN
This work presents a novel coefficient optimization algorithm to reduce the area and improve the performance of finite impulse response (FIR) filter designs.
Two basic architectures are commonly used in filters—direct and transposed.
The coefficients of a filter can be encoded in the fewest possible nonzero bits using canonic signed digit (CSD) expressions.
The proposed optimization algorithm can share common subexpressions (CS) and reduce the number of replicate operations that involve the CSD coefficients of filters with a transposed architecture.
The effectiveness of the algorithm is confirmed by using filters with the collision detection multiple access (CDMA) standard, the 121-tap high-pass band, and 105- and 325-tap low-pass bands as benchmarks.
For example, the proposed algorithm used in the optimization of 105-tap filter has a 30.44% smaller combinational logic area and a 16.69% better throughput/area than those of the best design that has been developed to date.
Experimental results reveal that the proposed algorithm outperforms earlier designs.
