Based On The Development Of The Pc755 And Pc107a Single-board Computer

Electronic reconnaissance is using electronic equipment on enemy communications, radar, navigation and electronic jamming devices such as a radiation electromagnetic signal detection, receive identification, analysis, and positioning, intelligences, or based on implementing anti-electronic and reverse against measures. From the electronic reconnaissance definition on look, in electronic reconnaissance systems, control, communication and signal processing function units are indispensable.Along with the development of embedded systems, industrial control, communication and signal processing field for embedded computing needs higher and higher. PowerPC G3 series of typical CPU PC755 in overall performance on very outstanding, tie-in bridge PC107A can be formed a powerful chips embedded key processing module. This paper is based on the core module, embedded computer with various peripheral, completed the embedded computer hardware design veneer.VxWorks is the Wind River System company established in 1983, design and development of an embedded real-time operating System, and has high reliability and good real-time performance, can cut sexual characteristics. Its development environment for Tornado or Workbench, provides richer debugging, simulation environment and tools.The paper mainly discusses using various embedded hardware and software development tools and techniques of a electronic reconnaissance system control processing unit of hardware design steps and the hardware platform in the process of establishing VxWorks operating system. The paper emphasized outstanding "core processor module," the core role.Specimen design process, use high-speed PCB design technology to solve the veneer computer walking at high speed line and more power distribution and other hardware design difficulties; Using the FPGA technology to achieve the PCI Bus to Local Bus Bus conversion and the serial interrupt design such logic design difficulties; Using DSP technology development guarantee the digital 1553B mil STD communication system of high efficiency running, Using low-level software development techniques completed within plate all hardware in VxWorks operating system under the bottom of the drive design and user interface function of writing.The paper discusses, we can see the PowerPC processor and VxWorks operating system that a powerful combination of embedded in industrial control and signal processing fields have good application prospect.
