工程师在用Keil开发程序时，在代码性能要求较高的场合，需要对代码段的执行时间作统计。比如在做LED显示屏软件扫描程序，或一些定时采集数据程序，如果在软件仿真的时候就能够清晰知道代码段的运行时间，那就可以对程序进行优化，或者插入汇编代码(asm)达到最高运行速度。 关键字:Keil DLL C语言 ASM 汇编-engineers in the development process with Keil, the code performance requirements higher occasions, need to block the execution time statistics. For example, in the software do LED scanning procedures, or some regular data collection procedures, If the software simulation time can understand clearly code of the running time, it can process optimization, or insert code compilation (asm2) to achieve maximum speed.
