【Abstract】 This paper introduces the investigation of the ARM+DSP embedded simulation platform, the scheme of ARM+DSP Embedded Platform includes the design of man machine interchange and the peripheral circuits. The software is also described in detail for the completion of real-time operating system μC/OS-II, the foundation of simulation application program and embedded graphic user interface. They have been successfully applied to the marine electric propulsion simulation system, providing real-time dynamic load (vessel engine propeller) characteristics for propulsion motor. The aforementioned systems have provided a new technical route, as well as a new exploitation platform, for the development of marine electric propulsion simulation system. The following jobs were done by the author:(1) Expanding man machine interchange, communication interface circuits and the peripheral circuits of the ARM+DSP Simulation Platform.(2) Building up the FAT 16 file system.(3) Writing the BSP board support package and the drive procedure.(4) Writing the particular embedded graphic user interface program according to the propulsion power system.(5) Coordinating the debugging of the hardware and software system. Practical development flow of embedded system is used as a clue toorganize materials and construct the dissertation. In terms of introduction, Chapter 1 introduces the project background, current research status of ARM+DSP at home and abroad, tasks, innovational points and meaning; Chapter 2 discusses the fundamental architecture and implementation method of the embedded simulation platform; Chapter 3 illuminates the method of porting embedded RTOS μC/OS-II to TMS320VC547x processors, under the CCS OMAP compile environment; discuss expanding the μC/OS-II, building up the more integrative RTOS; Chapter 4 introduces the designing of embedded graphic user interface program; Chapter 5 discussed to building up application program based on the RTOS μC/OS-II; Chapter 6 summarizes the dissertation and presents prospects.更多还原
