1. A real - time operation simulation system of 3d medical image base d pc 2. On - line , real - time operation 3. Analysis and implementation of embedded real - time operation system porting technology 4. Delta file 3 . 0 is the file system component of the embedded real - time operation system - delta os 5. Hardware implementation of genetic algorithms is critical for those applications , which require real - time operation 6. The features , parts and task scheduling method of embedded real - time operation system c / os - ii are introduced first 7. It is very expensive to embed real - time extension on windows or windows nt or use commercial real - time operation system 8. Combing the basic computer graphic theory and drawing classes provided by mfc , we complete the graphic drawing and real - time operation 9. This kind of sensor network also can be used in the environment requiring more real - time operation after some appropriate improvement 10. Therefore , i gave emphasis to study embedded system and embedded real - time operation system in process of exploitation
