We present in this paper a study of a framework for a FIR filter with fixed coefficients targeting CMOS 0.35´ for binary standard and redundant representations. Booth recoded and Lefevre constant multipliers are used. The internal data coding being both borrow-save and carry-save, the framework manages the generation of adapted adders.
