Description: eXtremeDB完全工作在主内存中，不基于文件系统，减少了诸如磁盘访问、文件I/O操作、缓存同步等开销，使得eXt remeDB的存取速度提高到极限；通过数据库定义语言面向应用系统定制的API使得eXtremeDB能够面向应用最优化；事 件触发、字段优先级等特色使得eXtremeDB管理实时数据时具有确定性。
eXtremeDB根据用户需求定义的API使得eXtremeDB与应用程序无缝集成。因此，eXtremeDB不仅在系 统中嵌入，而且“嵌入”在应用程序中，是一种真正的嵌入式实时数据库。在资源紧凑的系统中，eXtremeDB基本内存开销在6 0K到100K左右；对于大量实时数据需管理的情形,eXtremeDB最大一表格的记录总数可以达到2,147,483,64 7条。
eXtremeDB直观易用的，使您在零学习周期的情况下使用它管理实时数据。不论是VxWorks、WinCE、嵌入式Lin ux还是UNIX、Solaris，eXtremeDB都能出色地进行数据管理。
-eXtremeDB entirely in main memory, it is not based on the file system, such as reducing disk access, file I / O operations, cache synchronization overhead, making eXt remeDB access speed to the limit; Through the database definition language-oriented application system customization API to make eXtremeDB Application-oriented optimization; trigger events, such as field-level priority eXtremeDB characteristics makes real-time data management certainty. EXtremeDB user requirements definition API makes eXtremeDB with the seamless integration of applications. Therefore, not only eXtremeDB embedded in the system, but "embedded" in the application process, is a true embedded real-time database. Resources compact system, eXtremeDB basic memory overhead in six 0K to about 100K; For a larg

Description: This project is created using the Keil ARM CA Compiler.
The Logic Analyzer built into the simulator may be used to monitor and display any variable or peripheral I/O register. It is already configured to show the PWM output signal on PORT3.0 and PORT3.1
This ARM Example may be debugged using only the uVision Simulator and your PC--no additional hardware or evaluation boards are required. The Simulator provides cycle-accurate simulation of all on-chip peripherals of the ADuC7000 device series.
You may create various input signals like digital pulses, sine waves, sawtooth waves, and square waves using signal functions which you write in C. Signal functions run in the background in the simulator within timing constraints you configure. In this example, several signal functions are defined in the included Startup_SIM.INI file.
