Design and Implementation of ARP Functionality Based on VHDL

Purpose: In order to alleviate the related CPU workload of processing protocol stack, recoding the ARP protocol from TCP/IP protocol stack with hardware language VHDL, and the end to implement it on hardware platform. Methodology: According to functions, separating ARP protocol into two functional modules, creating limited state machine respectively and programming, at last integrating them on Xilinx ISE7.1i integrated environment, to implement functional simulation separately on ModelSim SE 6.0C at the end. Results: Based on the simulation results data, re-design the ARP protocol model which can replace the related functions in TCP/IP protocol stack. Conclusion: The success of ARP protocol module redesign with VHDL language, will drive the development of off-load engine technologies of TCP/IP protocol. Of course it will bring a new development of network also. In the next few years, it will promote a rapid development hot spot of network communication.
