摘　　要：由于DM9000A需要复杂的初始化流程,因此多采用ARM或者内嵌CPU的FPGA驱动,而使用这两者通常都不能充分利用DM9000A的网络带宽。将DM9000A应用在以FPGA器件为核心器件的网络相机系统中。为了提高DM9000A的网络发送带宽,对DM9000A在FPGA平台上的使用提出两点改进,并在应用系统中验证了改进的可行性。With complex initialization steps,DM9000A is mostly drove by ARM or FPGA with embedded CPU, both of which would reduce the network throughput of DM9000A. For improving sending throughput, bringing forward two optimizations for using DM9000A on FPGA based platform, and validating it in application system.
