On the Design of Scalable Massively Parallel CRC Circuits

This paper presents a scalable massively parallel CRC architecture for high-speed network processing. The proposed method considers wide data busses, which result in highest throughput. In addition, data streams are processed without interrupts. An investigated 65nm-ASIC implementation example for 32-bit CRC encoding operates on 58 GBps data streams at reasonable costs (0.036 mm²). The proposed method can be exploited furthermore in order to develop a configurable circuit for a group of generator polynomials, without the requirement of fully programmable architecture.
