Design And Realization Of Embedded System On EP9315 Microprocessor

Based on the research of the airborne multi-function MMW radar, the design and realization of the embedded system on ARM EP9315 microprocessor is researched in this dissertation.The system based on the mechanism of the airborne multi-function MMW radar simulates the operation principle of the signal processing and data processing extension, and provides a self-contained debugging environment for the validation of the target recognition algorithm. The system communicates through VEM bus. so it can also provides a technical support condition for development and realization of related system communicated with VEM bus.High performance, low power and abundant external port are utilized sufficiently, which makes the system sufficient and compact. The software of the system is realized by VxWorks operation system with high real time and clipping performance, which makes top application convenient.Firstly this paper presents the application background of the system and describes the related technique of the embedded system. The main function block and chip selection is conformed according to functional requirement. On the basis of the main chip selection we designed the hardware system and introduced the design and debugging of the external port circuit in detail. The development of software system is described later, which includes VxWorks operation system and its exploiture environment Tornado, the conception and design principle of BSP(Board Support Package). The elementary design, transplantation and debugging of BSP iscarried out according to hardware system.At last, Summary of this dissertation is made and the problems which need further research are pointed out.
