| Abstract: | This paper implements an integrated IP telephony gateway, and analyses data processing of IP telephony gateway. According to the theories of multiprocessor and Stochastic Petri Nets, the SPN model of the integrated IP telephony gateway is set up, and mathematical relationship of processor's efficiency is studied. Finally, this paper concludes that the efficiency of processor may be improved if the global memory of the IP telephony gateway adopts uses ping pang mode, and DSP's on chip memory. |
