The standard of OSEK/VDX which used in the embedded operating system of car was analysized, and based on this, to select the open-source real-time operating system μC/OS-II as a operation system that will be loaded in the control chip. After that the kernel structure of the μC/OS-II was analysized, and modified the kernel of the system in accordance with OSEK/VDX standards, then translated the μC/OS-II system to the LPC2131 development board for the follow-up application development laid the foundation.

Loading Patterns

With the development of information technology, ERTOS(Embedded Real-Time Operating System) not only has involved in the scientific research and engineering domains, but also has many affinities people's life. Loading pattern performance is the most important performance of Embedded Operating System. It needs dispatching all available resources to achieve real-time task. In order to correctly evaluate the performance of a real-time Embedded Operating System, we must be scientific, systematic approach to ERTOS study of the comprehensive performance and accurate testing. This article discusses three loading patterns and the layout of the memory map on the Flash, RAM and external storage media, with tested on hardware platform it description the advantages and disadvantages of this three loading pattern.

Vibration Drilling

Based on the in-depth study of embedded systems technology and characteristics of the ultrasonic vibration drilling process, the new CNC system for ultrasonic vibration drilling based on ARM and μC / OS-II embedded was proposed in this paper. For this system, the kernel of hardware is the 32 -bit embedded CPU LPC2210 with characteristics of high performance and low power consumption. And it is also equipped with the required peripheral modules to extend itself to one whole hardware system and the interface circuit. Its software is based on μC / OS -II real -time embedded operating system, and the required application software needs to be developed so as to turn μC / OS- II real -time embedded operating system into one practical embedded ultrasonic CNC drilling.

Embedded Systems based on ARM processors are used extensively in mobile devices like PDA’s and MP3 players.ARM is 32bit Reduced Instruction Set Computer(RISC).Windows CE is real time, multi-task operating system that works on a 32-bit processor. This paper suggests Windows CE embedded operating system, and how to build a platform for Windows CE operating system embedded in a LS5310 ARM11 microprocessor S3C6410 and also the design of Windows CE embedded applications based on Embedded VC++ 4.0. Here we are employing RS232 serial port of ARM 11 processor and ZigBee wireless data communications module to design an application for a ZigBee location system with an easy-to-use interface. It performs multiple functions like information and data receiving, saving, processing and display. It has advantages of high performance, low cost, and low power consumption and is an important component of the network locating system.

Time Offset

The TTCAN network protocols have been achieved based on the MPC5121e microprocessor in embedded real-time operating system VxWorks. The optimal solution is calling the callback function of the interrupt service routine to complete the CAN network data transmission and using the auxiliary clock to calculate the local time offset.
