摘　　要：研究了基于ARM微处理器S3C2410A与TMS320C6211 DSP双核体系结构的嵌入式交通信息视频检测系统的设计方案,设计了ARM和DSP系统单元间通信接口的硬件连接方案和驱动程序。ARM系统单元采用ARM-Linux嵌入式操作系统,通过DSP的HPI接口与DSP系统单元进行通信,将其看作一个字符型外部设备进行读写操作。系统具有性能高、功耗和成本低、稳定性和实时性好、可扩展性强等优点。This paper presents a new design of dual-cored embedded video vehicular detection based on ARM processor S3C2410A and TMS320C6211 DSP. It lays emphasis on the design of communication interface between ARM and DSP units, including hardware implementation and software program. Exploiting ARM-Linux as embedded operating system, ARM unit communicates with DSP unit in real time through the host port interface （HPI） of DSE ARM regards the HPI as a character device to do operations such as reading and writing on it. This system has advantages of high performance, low cost, low power consumption, good stability and expandability.
