Functional Testing Methods For Embedded Operating Systems And Achieved

In the time of Post-PC, which contemporary digital information technology develops rapidly, with embedded system application invasive, numerous embedded real-time operating systems are booming. Because special development environment, the test of embedded operating system is difficult. But the test is important to assure the quality of embedded systems. The purpose of this thesis is to research and discuss software test methods of embedded operating system based onμC/OS.Operating systemμC/OS is simple, real-time, scalable, romable, portable, multi-tasking, robust and reliable, especially it's an open source OS, suitable for students to study, and there have some business applications base on it with a lot of expanded functions. This thesis tells the principle and its function characteristic, to understand the test of the function ofμC/OS mainly.The embedded operating systemμC/OS function is tested and operated on PC platform, compiling directly through Borland C and VC ++. The function test mainly concentrates on the kernel ofμC/OS, which includes task management tests, memory management test, interrupt test, communication management test, and the task management test is the focus. Through test, we can find out thatμC/OS is excellence. And the memory management is suitable for little and compact environments. According to the test, we can find the operating system is designed finely, very suitable for study.
