Design And Application Of Embedded Real-time Operating System Based On DSP

In recent years, with the development of Communications, Automotive Electronics and Consumer Appliance, the new direction of development is Application Development and Graphical User Interface Development based on embedded system. So, Construction an embeddedreal -time operation system based on DSP, and developing software and hardware multi-task, real-time application and GUI has important Practical Values.This thesis firstly analysis development status and future trends of embedded system and choose the embedded DSP TMS320C54X, embedded RTOSμC/OS-Ⅱand embedded GUIμC/GUI as software and hardware of this system thinking about Factors such as Cost and Practical needs.When to construct the RTOS of DSP, research the characteristics of TMS320C5402 andμC/OS-Ⅱabove all, and give the General methods and conditions of transplanting RTOS to DSP, give the detailed methods and procedures of transplantingμC/OS-Ⅱto TMS320C5402, then test the system and research the methods of developing real-time multi-task Application. Finally, improve the RTOS core partly to promote the functions and operating efficiency of embedded system.When to develop embedded GUI, The hardware platform is designed with TMS320C5402 mainstream DSP as its microcontroller, with DV12864B Embedded T6963C as LCD Module. the software is designed withμC/OS-Ⅱas software developing platform, and withμC/GUI because of better Human-Computer Interaction and Application Programming Interface. Finally design the Hardware circuit, give the Detailed procedures of transplantingμC/GUI to DSP, and develop the Simple multi-task GUI.The thesis gives a summary of all the work and puts forward the successive destination at last.
