摘要
介绍了安徽省重点实验室——智能建筑实验室中自行研制的智能建筑图像视频处理信息传递系统。研究基于IEEE1394串行总线的DSP双向数据传输系统技术,在系统硬件结构描述基础上详细分析系统的数据流向与工作流程。在异步传输和等时传输的实现过程中给出了具体的链路层控制芯片的端口选择问题和等时传输过程中对信道、带宽的申请、占用、释放方法。
In this paper we introduced the image and video information delivery system in intelligent building and study the technique of the bidirectional data transfer DSP system based on IEEE1394 serial bus. Described the data flow and workflow of the system based on the hardware structure in detail. In the realization of the asynchronous transfer and isochronous transfer, Give the port selection process of a specific link layer controller chip and methods of channel＆bandwidth such as the application, the occupancy, the release method during the isochronous transfer process.
