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-rnbased solution of an entity with simplified MAC sublayer function is given in this paper. The MAC module canrnachieve a high-speed data acquisition,and through the processing to customized frames with non-standard structurernby the MAC module,the efficient system data scheduling was implemented. Now the solution has been applied to thernpractical network testing instruments and good result has been gotten.
