摘要: |
介绍了一种基于TMS320VC5402 DSP芯片实现的嵌入式语音处理通用平台。该平台利用巧妙的译码电路,在实现扩展最大48K外部数据SRAM的同时,也完成了系统的独立平行加载。同时平台还扩展了良好的人机交互模块。给出了系统硬件结构图、主程序流程图及实现系统并行自举的具体步骤。 |

Abstract: |
A universal embedded speech processing platform based on TMS320VCS402 DSP is presented. Making use of smart coding circuit, maximal 48K extern DATA SRAM is expanded, and meanwhile independent parallel boot of the system is accomplished. Human - machine interface of keys and LCD display are also extended. Figure of system hardware structure, flow chart of main program and detail steps of realizing parallel boot are provided. |
