摘要
网络部分是纸币清分机通信系统的重要模块,通过对TCP/IP协议中的ARP协议、IP协议、ICMP协议和UDP协议进行分析,结合系统主芯片TMS320DM6446特性,提出了基于双核处理器TMS320DM6446与IP101A以太网控制器的网络通信硬件设计;经过试验,完成了基于TCP/IP协议的纸币清分机通信系统设计目标。
Ethernet part is an important module of banknote sorter. By analyzing ARP protocol,IP protocol,ICMP protocol and UDP protocol in TCP/IP protocol and combining the characteristics of main chip in the system, the hardware design of network communication with double core processor TMS320DM6446 and Ethernet controller IP101A is proposed. The test results show that the communication of banknote sorter with TCP/IP protocol is completed.
