AbstractQImaging公司的RETIGA 2000R相机具有高分辨率、高速度、低电子热噪声等众多优点,在明暗视场、机器视觉、度量学和冶金等领域广泛应用。由于相机192万象素的高分辨率,需要传输的图像数据量巨大,对输出接口提出挑战。相机的输出接口为1394接口。作为一种高速串行总线,IEEE 1394a支持的最高速率达400Mbps,其中1394b的速率可达800Mbps、1.6Gbps、3.2Gbps。1394总线支持点对点传输,不需要主机干预即可实现节点间通信,通信方式分为等时传输和异步传输。同时1394总线支持即插即用、公平仲裁、线缆供电等功能。因此,1394总线成为音视频传输领域设计的最佳选择。 本课题以RETIGA相机接口功能出发,在充分理解1394协议的通信模型和体系结构的基础上,完成对相机接口控制数据的解析,并提出一个1394接口电路系统方案,并完成系统的硬件设计和软件编程及调试,实现了相机和图像处理平台的连接。硬件设计以FPGA作为系统控制器,采用的1394协议芯片为TI公司的链路层控制芯片TSB12LV01B和物理层控制芯片TSB41AB3。硬件设计模块包括FPGA和链路层接口模块、FPGA和SRAM模块、物理层和链路层接口模块以及物理层的1394端口模块及外围电路设计。软件设计主要以Spartan II FPGA作为平台,利用可编程技术,在ISE 8.1环境下完成了总线初始化、自标示、树标识、根节点检测和配置、异步数据包配置相机以及接收数据包等功能。 本论文首先介绍了IEEE 1394传输协议及体系结构,然后介绍了相机控制数据的解析过程和难点,并根据研究室要求和具体的控制芯片,完成了基于FPGA的IEEE 1394接口电路的硬件设计和功能软件设计,并实现了相机的等时资源管理器和循环控制器功能,对以后1394总线的工作方式设计和传输模型研究具有重要借鉴意义。
Other AbstractThe QImaging RETIGA 2000R digital camera features enhanced visible-range quantum efficiency resulting in high sensitivity that is ideal for bright field, machine vision, metrology, and metallurgical imaging application. Its high speed data rate requires a high readout speed interface, which is 1394 interface. As a kind of high-speed serial bus protocol, IEEE 1394a supports a data rate of 400Mbps and 1394b can support a data rate of 800Mbps, 1.6Gbps and 3.2Gbps. IEEE 1394 bus has a lot of advantages compared with other serial bus protocol, such as its high speed and that it can support Peer to Peer transmission, Synchronous and Asynchronous transmission, Plug and Play, fair arbitration and cable powering. This project put forwarded a 1394 interface circuit scheme on the basis of a camera interface and the knowledge of the IEEE 1394 communication model, and then completed the hardware design and software design of this system, which achieved the linking between camera and the image processing platform. Hardware core components included FPGA, TI's physical-layer-controller chip TSB41AB3 and link-layer-controller chip TSB12LV01B. Hardware design module was comprised of FPGA and link-layer interface, FPGA and SRAMs module, 1394 physical-layer and link-layer interface and 1394 port circuit design. Software design was mainly about the VHDL programming on the Spartan II FPGA, which realized the function of the system initialization, tree- identification, self-identification and the data packet's transmitting and receiving. This paper's purpose is to introduce the IEEE 1394 protocol and system architecture, and then accomplish the hardware and software design of the 1394 interface circuit, which is based on our institute's needs and concrete controller chips. Test results show that this design realizes the function of resource manager and cycle master of the camera, which is valuable for the future design and research
