Delphi:内存读写工具Delphi源码下载，内含CPU周期计算操作库（作者：侯思松）。

　　function CPUCycleCounter():int64 register {获取当前CPU周期计数(CPU周期数)}

　　 function CPUTimeCounter():Extended {获取当前时间计数(us),利用CPU内部指令完成}

　　 function GetCPUFrequency():int64 overload {获得CPU的主频,准确快速}

　　 {$ENDIF}

　　功能方面就这些，肯定有不足之处，甚至还有许多需要完善的地方，先这样，大家共同交流。

-Delphi: Delphi source code download tools to read and write memory, embedded CPU cycles calculated manipulation library (Author: Housi Song).

function CPUCycleCounter (): int64 register　{get current CPU cycle count (CPU cycles)}

function CPUTimeCounter (): Extended　{get the current time count (us), the use of internal CPU instruction is completed}

function GetCPUFrequency (): int64　overload　{get CPU clock speed, accurate and fast}

{$ ENDIF}

These functions, and certainly inadequate, and even many need to be perfected, first so that we can exchange.
