摘　　要：提出一种嵌入式异构多处理器系统的结构模型,论述这种系统的通信机制,并阐述在基于这种嵌入式异构多处理器系统模型的实时图像处理系统中,运算节点采用由TI公司的TMS320C6416DSP芯片构造的信号处理板时,在运算节点与主控节点之间实现高速数据传输的方法,该方法极大地提高了数据的传输速度。Proposes a structural model of embedded isomerous multi-processor system, and describes the mechanism of communication of such system. Furthermore, in the case that a signal processing device on TMS320C6416 DSP from TI is used as processing node, in the real-time image processing system based on such embedded isomerous multi-processor system model, a new method of high-speed data transmission between the processing node and the host control node is proposed, by which the data transmission speed is greatly improved.
