| Wireless trunking communication system is a system which provides many services for professional users including task command and control, data transmission, information sending and receiving and position locating etc. it has a broad market prospect.OMAP platform, which is issued by TI company in US these years, is a very popular mobile terminal solution platform in the market. Based on the advanced architecture design, OMAP has good information control and processing ability with low power consumption. So it is much suitable for multimedia business application development in the mobile terminals. And it has been widely used in GSM and 3G system.In this paper, based on the TMS320C55x DSP of OMAP 5912 architecture, we make deep research of the AMR speech codec realization and optimization in DSP which is widely used in trunking communication. As the particularity of the DSP system, much optimization is made for the key link of the transplant; meanwhile, CCS simulation software platform is built and correctly configured. |
