DSP 28335的网卡芯片RTL8019AS是高度集成的以太网控制器，符合IEEE802.3标准，可以通过网络接口同时发送和接收数据。本文主要是基于以太网TCP/IP协议实现xPC目标与DSP间的全双工通信以及通信的可靠性。在Simulink中搭建以太网发送/接收模型，通过编译下载到xPC目标机运行。 xPC目标机对传输数据进行封装并打包通过以太网发送给DSP，DSP接收xPC的数据包进行解包还原然后反馈给xPC目标进行比较。实验结果显示基于以太网能够实现快速xPC目标与DSP的通信。

DSP 28335 chip card RTL8019AS is a highly integrated Ethernet controller, in line with IEEE802.3 standard, it can send and receive data through the network interface at the same time. This paper is based on Ethernet TCP/IP protocol to achieve full-duplex communication between the DSP and xPC Target. Establish Ethernet transmit / receive model in Simulink, downloaded to compile xPC target machine is running. xPC target machine to encapsulate and transmit data package sent via Ethernet to the DSP, DSP receive xPC packets to unpack and then feedback to xPC target comparison. Experimental results show that Ethernet-based communication can be achieved quickly between DSP and xPC Target.
