[Abstract]:Digital signal controller (DSC) is a new type of microprocessor combining digital signal processor (DSP) and microcontroller (MCU), which is widely used in multimedia processing, instrument and instrument. Health care, home appliances and other fields, has a broad market prospects. With the development of semiconductor manufacturing technology, a variety of new DSC chips are emerging, and their application and development methods are also developing with the development of technology. The application research based on DSC has become one of the hotspots in the field of embedded systems. In the second half of 2010, Freescale Semiconductor Co., Ltd. launched DSC chip MC56F8257, for middle end product market, commissioned by Freescale, Suzhou University Freescale embedded Laboratory to undertake the preliminary research and application of the chip. According to the requirements of Freescale Company, and considering the characteristics and development trend of embedded DSC market, this paper combines the design idea of component software and hardware and the design method of software engineering. A DSC embedded development platform based on Freescale MC56F8257 is designed, which includes hardware development board, bottom driver component and on-line debugger. The main work of this paper is as follows: (1) the characteristics of MC56F8257DSC chip are analyzed. Combined with the design principle of embedded hardware, the design scheme of hardware development board is put forward, the hardware schematic diagram and the design method of PCB board are described in detail, and the testing work of hardware system is completed. (2) according to the design idea of software engineering and the characteristics of embedded software, the design scheme of bottom driver component based on component design is put forward, and the design and encapsulation method of bottom driver component are explained in detail. (3) based on the analysis of feasibility, a universal on-line debugger is designed, which is suitable for Freescale series microprocessors. The debugger unifies a variety of debugging interfaces to facilitate the use of users and greatly reduce the cost. (4) the project design is applied to the actual project-forklift electronic steering control system. The system design scheme, related control algorithm and control flow are given, and the correctness and stability of the project are verified. The practice shows that using the development platform of the project design can reduce the difficulty of the development, improve the efficiency of the development, complete the requirements of the project design, and prove the practical significance and application value of the project design.
