基于可变数据结构的MAC采集模块的设计

Design of MAC Acquisition Module Based on Alterable Data Structure

针对可变数据结构应用中的介质访问控制(MAC)模块,提出了一种简化的MAC子层功能实体的FPGA实现方案。该MAC模块在完成高速数据采集的同时,通过对自定义的非标准结构帧的处理,从而实现高效的系统数据传输调度。目前,该方案已经应用于实际的网络监测仪表中,效果良好。

Supplement to medium access control （MAC）module in the application of alterable data structure,a FPGA- based solution of an entity with simplified MAC sublayer function is given in this paper. The MAC module can achieve a high-speed data acquisition,and through the processing to customized frames with non-standard structure by the MAC module ,the efficient system data scheduling was implemented. Now the solution has been applied to the practical network testing instruments and good result has been gotten.
