摘　　要：主要介绍使用基于Ti Davinci架构的图像处理SDK软件系统设计。软件系统运行于基于TMS320DM6467的智能交通专用主机,支持智能交通领域的多种图像处理算法,算法运行于DSP核心,通过ARM与DSP核心间RPC机制,使ARM运行的应用软件可透明地调用相应算法。针对嵌入式系统的有限内存,系统分别在ARM和DSP核心端完成内存优化。针对DSP核心的硬件架构架构,实现相关算法的指令优化。系统可应用于智能交通领域多种系统的开发。This Article mainly introduce the design of the Image manipulation SDK for the software sys- tem. This software running platform is special intelligent traffic machine which is based on TMS320DM6467. Our this system can be used for many image manipulation algorithm which run in the core of DSP processor and communicate with ARM using the way of RPC from which can let the ARM ap- plication clarifying invoke the DSP algorithm in intelligent traffic field. For the reason of the limition of the embedded system＇s memory,we have optimized the memory access for both of ARM and DSP end. we also optimized the instruction of corresponding algorithm to the hareware structure of DSP core. Our this system could be used for more other system development usage in intelligent traffic field.
