Based On The Analysis Of Embedded Real-time Operating System Vxworks Platform And Research

VxWorks is a micro-kemel, high-performance,and scalable Real-time OperatingSystem developed by Wind River System Inc.At present,in the Real-time OperatingSystem of more than 200 kinds all over the world, VxWorks is the most famous andextensive.On the American market, VxWorks right keep the number one of real-timeOperating Systems in recent years. One of the reasons that VxWorks is so popular ispredominant performance in real-time communication.Its network speed and throughoutkeep a leading level. The thesis put forward to its viewpoint at the basic platform ofVxWorks, analyze the key modules,and built the embedded IDE. At last,design the driverof the CAN director on the platform of VxWorks.The analyse of the operation system inthie thesis is not aim at any hardware platform,it's all hardware irrelevant description.The firt part of this thesis mainly discuss the basic concept and theory ofVxWorks,analyze the basic structure,discuss the basic part of the kernel wind.Analyze thememory manage,multitask mechanism,network communicate,I/O system and filesystem.And build the embedded IDE based on hardware.Discuss the concept and tailorsteps of BSP, and how to run the bootrom.The second part of this thesis analyze the serialport driver of VxWorks,and the structure of CAN bus.Finish the serial port driver design ofthe CAN director SJA1000.
