cpuid.h

获取CPU信息的类

///////////////////////////////////////////////////////////////////////////
// 文 件 名: cpuid.h
// 功    能: 通过 cpuid 指令,获取 CPU 信息的头文件
// 编译环境: VC++ 6.0 (Windows XP SP2)
//
// 用    法: 1. 声明一个对象: CCPUID cpuid;
//           2. 运行功能函数: cpuid.Run();
//           3. 现在你就可以调用想要的数据了.
//              如处理器商标字符串: cpuid.sProcessorStr
//

                            说          明
CPUID 指令在VC中的用法:
      _asm
	  {
		mov  eax, X        // X 取以下的输入值
		cpuid
		mov  Y, EAX        // Y,Z... 表示将EAX,EBX,ECX,EDX中的值保存起来...
		mov  Z, EBX
		...
	  }

-----------------------------------------

输入: EAX = 00H
输出: EAX = dwBaseMaxVal                    // Maximum input value for basic CPUID information
	  EBX, ECX, EDX = sFactory[13]          // 处理器生产厂商信息

-----------------------------------------

输入: EAX = 01H
输出: EAX = dwVerInfo                       // Version information: Type, Family, Model, and Stepping ID
      EBX = dwBaseFeatureInfo               // Bits 7-0: Brand Index.   Bits 15-8: CLFLUSH line size ...
	  ECX = dwExFeatureInfo                 // Extended feature information
	  EDX = dwFeatureInfo                   // Feature information

-----------------------------------------

输入: EAX = 02H
输出: EAX, EBX, ECX, EDX = dwCacheTLB[4]    // Cache and TLB information
	  EAX :  0-- 7 Bit Instruction TLB
	         8--15 Bit Instruction TLB
			16--23 Bit Data TLB
			24--31 Bit Instruction TLB
	  EDX :  0-- 7 Bit 2nd level Cache
	         8--15 Bit 1st level Instruction
			16--23 Bit Data TLB
			24--31 Bit 1st level Data

-----------------------------------------

输入: EAX = 03H
输出: ECX, EDX = dwProcessorSN[2]           // Processor serial number(Available in Pentium III processor only)

-----------------------------------------

输入: EAX = 80000000H
输出: EAX = dwExMaxValue                    // Maximum input value for Extended Function CPUID information

-----------------------------------------

输入: EAX = 80000001H
输出: EAX = dwExFeature                     // Extended Processor Signature and Extended Feature Bits
      ECX =
	  EDX =

-----------------------------------------

输入: EAX = 80000002H -- 80000004H
输出: EAX, EBX, ECX, EDX = sProcessorStr[49]  // Processor Brand String
