hardware address
3.The paper gives a description of the hardware environment. The code design of the Address Resolution Protocol(ARP) using in Ethernet-communication and the tidy Transfer Control Protocol/Internet Protocol(TCP/IP) using in data transfer for embedded system are also described. At last the paper also introduces the test method of the design code.
8.The frame structure characteristics of Ethernet, Ethernet controlling chip RTL8019AS and hardware design for the implementation of Ethernet communication with MCS51 single chip microprocessor are presented in this paper. The Assemble Language is used to realize ARP (Address Resolution Protocol) and system passed debugging.
