MPC8260与TMS320VC5410HPI接口的实现与应用

Implementation and Application of Connection between MPC8260 and TMS320VC5410 Host Port Interface

简要介绍了通用通信处理器MPC8260与数字信号处理芯片TMS320VC5410的结构与主要特点,提出了MPC8260的GPCM接口与TMS320VC5410的HPI接口连接方案,实现了数据在处理器与DSP之间的高效传输。该接口方案应用于cdma20001x声码器系统中,在实现语音编解码功能的基础上可以动态配置声码器资源。

This paper introduces the structure and primary characteristics of the versatile communications processor MPC8260 and the digital signal processor TMS320VC5410. A method that can implement seamless connection between the MPC8260's GPCM and the host port interface of TMS320VC5410 is proposed. With this method data can be transmitted efficiently between the processor and the DSP. This Design is applied to codec implementation of a cdma2000 1x system and can configure codecs dynamically.
