Design and Analysis of Digital Ratioed Compressors for Inner Product Processing

[摘要] Inner product calculations are often required in digital neural computing. The criticalpath of the inner product of two binary vectors is the carry propagation delay generatedfrom individual product terms. In this work, two architectures to arrange digital ratioedcompressors are presented to reduce the carry propagation delay in the critical path.Besides, the carry propagation delay estimation of these compressor building blocks isderived and compared. The theoretical analysis and Verilog simulation both indicatethat one of the compressor building blocks we present here might offer a sub-optimalsolution for the basic building blocks used in digital hardware realization of the innerproduct computation.
