Abstract :
The architecture design of VOIP videophone system composed of TMS320DM642 and ARM9 is described in this paper firstly. Then the scheduling design of VOIP videophone under DSP / BIOS real-time operating system is introduced. The system control and data operation management achieved by HPI Interface design between DSP and ARM9 is elaborated further in detail. Practical results show that it has solved the complex scheduling and control of the system, improving the efficiency of the system implementation.
