Improved Design of C²PL 3-2 Compressors for Inner Product Processing

The inner product of two vectors might be one of the most frequently used mathematical operations in digital computation. The design style of inner product processor will become a critical issue of performance. So does its basic building block, i.e. 3-2 compressor. In this work, improved designs of 3-2 C²PL-based compressors are presented which can be used to build a fast inner product processor. The features of our compressors include a short delay minimized by HSPICE optimization, less transistor count, and high fan-out.
