Ucos - Ⅱ S3c44b0 Platform Design And Implementation

As an important element of intelligent and small-size equipment, embedded system has now widely used and plays a very important role in many fields such as national defence, industry control, traffic, energy sources, information technology and civil living。So the embedded operationg system is high-profile.And UC/OS-Ⅱ is a small and medium-sized, priority-based embedded real-time kernel, it features compact, stable performance,and the realization of the code is free. This thesis is based on the hardware paltform called S3C44B0microcontroller which is ARM7TDMI based and ports the μC/OS-Ⅱ on it.The thesis analyze the kernel’s structure and the characters of embedded system μC/OS-Ⅱ. It also researches it’s porting condition and implements deeply according to the structure of the mcu—s3c44b0:with the integrated development environment ADS vl.2and target micro-controller s3c44b0, analysis the system’s code design and implementation procedures;designs all files relation with the Real-time embedded operating system’s porting of uC/OS-Ⅱ,and the OS_CPU. H,OS_CPU_C.C and OS_CPU_A.S are3major design process for an in-depth analysis of the file; for each tranSPlanted file characteristics, SPecific analysis to the test method, using the compiler Tracker and application methods, verify that the migration code correctness and the system of support for multitasking.UC/OS-II embedded real-time operating system easy to port and is a mature, open source, free operating systems that significantly reduce the cost of development of real-time operating systems, improving the security of application of military products, while also lowering the threshold of studies and research, are ideal for domestic promotion, application.
