An Improved Approach for Cyclic-Redundant-Code Generation and Circuit Implementation for 40 Gb/s Ethernet
Chen Xiao-yin · 2015
Because the cyclic redundancy code defined in a 40Gb/s Ethernet specification had a long critical path to calculate,a method to increase the speed of CRC-32 based calculation was put forward.The circuit was simulated,and it was synthesized targeting SMIC 65 nm process by using Design Compiler.The synthesis results showed that the proposed method was correct.It could increase the speed of CRC generation and was highly applicable in ultra high-speed circuit design.
