Application of HPI in Data Communication of Master-Slave System
WU Xiao-pei · Computer Technology and Development · 2006
Data communication is a pivotal technology in the design of master-slave system. HPI(host port interface) is a kind of important peripheral of TI DSP.The aim of this paper is to introduce the HPI of TMS320C54x and its application in data communication.The conception of data communication is introduced;the structure and principle of HPI are introduced in detail.In the end,taking TMS320C5402DSP as example,introduces the hardware connections and software applications when communicating with C51,and also part of the procedure code was presented.From this scheme of data communication,may find out a series of advantages of HPI.For the design of complex system and flexible and novel scheme of data communication / share,there is a certain extent meaning of using for reference.
