Title: Data communication method between ARM and DSP in embedded machine vision system
Abstract: In order to realize real-time data communication between ARM S3C2440 and DSP TMS320C5402,a design method,via HPI interface,is proposed.The embedded machine vision system’s overall scheme is introduced,the circuit of hardware interface is designed,HPI work principle and functions of registers are described in detail,and drivers based on Linux operation system are designed.Practical applications prove that the host computer ARM can access all registers of DSP processor and the maximum transmission rate is 10Mbit/s.It can meet the requirements of embedded machine vision systems in real-time.
