A MODULAR DISTRIBUTED-ARITHMETIC IMPLEMENTATION OF THE INNER-PRODUCT AND ITS APPLICATION TO DIGITAL-FILTERS

A modular implementation of the inner product is proposed. The impleme ntation is based on distributed arithmetic and incorporates three type s of programmable quantization. It uses a single configurable cell and building blocks consisting of simple and regular structures that can be implemented efficiently in VLSI form. The design strategy developed can be used for the implementation of limit-cycle-free digital filter s and in a number of other digital signal processing applications wher e a quantized sum of products is required.
