話不多說，先看運行截圖：

代碼如下：

#include <iostream> #include <string> #include <windows.h>//存4個寄存器值 DWORD deax, debx, decx, dedx; void initCpu(DWORD veax) {__asm{mov eax, veaxcpuidmov deax, eaxmov debx, ebxmov decx, ecxmov dedx, edx} }long getCpuFreq() {int start, over;_asm{RDTSCmov start, eax}Sleep(50);_asm{RDTSCmov over, eax}return (over - start) / 50000; }std::string getManufactureID() {char manuID[25];memset(manuID, 0, sizeof(manuID));initCpu(0);memcpy(manuID + 0, &debx, 4); // copy to array memcpy(manuID + 4, &dedx, 4);memcpy(manuID + 8, &decx, 4);return manuID; }std::string getCpuType() {const DWORD id = 0x80000002; char cpuType[49];memset(cpuType, 0, sizeof(cpuType));for (DWORD t = 0; t < 3; t++){initCpu(id + t);memcpy(cpuType + 16 * t + 0, &deax, 4);memcpy(cpuType + 16 * t + 4, &debx, 4);memcpy(cpuType + 16 * t + 8, &decx, 4);memcpy(cpuType + 16 * t + 12, &dedx, 4);}return cpuType; }void getCpuInfo(){std::cout << "CPU主頻: " << getCpuFreq() << "MHz" << std::endl;std::cout << "CPU廠商: " << getManufactureID() << std::endl;std::cout << "CPU類型: " << getCpuType() << std::endl; }void main(){getCpuInfo();system("pause");return; }
