| There is no doubt that ethernet has been a popular communication method because it is easy to use,has low cost and high bandwidth,also has high stablity ,good compatibility and high security.network function has been regarded as a main system function development target in more and more embedded system.To MAC,which performs as a platform of media access management, how to solve the problem of huge amount data checkout, has always been a difficulty for data transfer.This paper tries to find a better solution of designing CRC32 algorithm of MAC for Embedded Ethernet Microprocessor. It uses a TOP to Bottom method, tries three ways as Matrix, replacement and pipeline.And based on way of pipeline it give out a realization of specific programs. |
