给定一个CPU型号,如何生成对应的cpuid指令注意不是获取是生成 ！

CPUID指令是intel IA32架构下获得CPU信息的汇编指令，可以得到CPU类型，型号，制造商信息，商标信息，序列号，缓存等一系列CPU相关的东西。

比如生成查询CPU的制造商信息(Vender ID String)的代码：

string CPUID::GetVID()

{

char cVID[13]; // 字符串，用来存储制造商信息

memset(cVID, 0, 13); // 把数组清0

Executecpuid(0); // 执行cpuid指令，使用输入参数 eax = 0

memcpy(cVID, &m_ebx, 4); // 复制前四个字符到数组

memcpy(cVID+4, &m_edx, 4); // 复制中间四个字符到数组

memcpy(cVID+8, &m_ecx, 4); // 复制最后四个字符到数组

return string(cVID); // 以string的形式返回

}

示例代码如下：

procedure TForm1Button1Click(Sender: TObject);

  type

    TCPUID = array[14] of longint;

  function GetCPUID: TCPUID;

  asm

    PUSH    EBX

  　PUSH    EDI

  　MOV     EDI,EAX    

  　MOV     EAX,1

  　DW      $A20F      

  　STOSD

  　MOV     EAX,EBX

  　STOSD

  　MOV     EAX,ECX

  　STOSD

  　MOV     EAX,EDX

  　STOSD

  　POP     EDI

  　POP     EBX

  end;

var

  aCpuId: TCpuID;

begin

  aCpuId := GetCPUID;

  ShowMessage('CPU 序列号是: ' + IntToHex(aCpuId[4],8) + IntToHex(aCpuId[1],8));

end;

与实际的对比：

///==============================获取CPU序列号========

package comtest;

import javaioIOException;

import javautilScanner;

public class CpuUtil {

public static void main(String[] args) throws IOException {

long start = SystemcurrentTimeMillis();

Process process = RuntimegetRuntime()exec(

new String[] { "wmic", "cpu", "get", "ProcessorId" });

processgetOutputStream()close();

Scanner sc = new Scanner(processgetInputStream());

String property = scnext();

String serial = scnext();

Systemoutprintln(property + ": " + serial);

Systemoutprintln("time:" + (SystemcurrentTimeMillis() - start));

}

}

//=======================获取硬盘序列号==========================

package comtest;
