用cpuid指令获取cpu信息(转)

最近在写 一个获取系统信息的Delphi组件,想得倒Cpu的id时,碰到了麻烦。上网查了好多资料,下了好多代码,结果还是没有解决问题,关于取Cpu的Id 众说纷纭,而且我试了好多,好像在几台机器上读到的CpuId好像都一样,(开发组机的机器,配置都一样,cpu当然也是一个型号的p4 1.8)。可cpu的id不应该一样吧,每个cpu应该有个唯一标识吧,笔者这样认为。
EAX寄存器,返回的信息在EAX,也就是说执行cupid寄存器赋值,在执行cupid的相关信息就在EAX,入口参数EAX
值设的不同,取得的信息也不同,我们可以写这样一个函数来获得Cpu的相关信息,当然也包括Id。
type
TCPUIDResult=record
eax:dword;
ebx:dword;
ecx:dword;
edx:dword;
end;
functionCPUID(EAX:DWord):TCPUIDResult;
vars1,s2,s3,s4:DWord;
begin
asm
pusheax
pushebx
pushecx
pushedx
moveax,EAX
//******************************************************//******************************************************
cpuid
movs1,EAX
movs2,EBX
movs3,EcX
movs4,Edx
popedx
popecx
popebx
popeax
end;
Result.EAX:=s1;
Result.EBX:=s2;
Result.EcX:=s3;
Result.EdX:=s4;
end;
也就是说,EAX传入3时获得是Cpuid,可为什么笔者获得的几台机器的cpuid是相同的呢?
自英特尔 486 问世以来,英特尔制造的每一款处理器都可以通过处理器设计过程中生成的 CPUID 字符串来辨别真伪(“真品英特尔® 处理器”)。然而,仅有少数几款含有附加 64 位(作为 CPUID 字符串的一部分)的处理器可以唯一识别。
英
特尔处理器序列号是在设计和的过程中指定的 96 位固定编码。CPUID 涉及了处理器系列、型号和步进的信息,可依据产品系列(例如奔腾或赛扬®
处理器)和制造工艺(例如 0.13 或 0.18
微米)划分处理器。在正常 32 位上就创建了处理器的序列号。这个编号是固定的,不由于系统的改变而变化。
有关读取编号的详情,请参阅和 0.13 微米工艺的奔腾 III 处理器版本不支持随奔腾 III 处理器而引入的序列号功能。
虽然无法唯一识别其它的处理器,但可以使用来获取“真品英特尔”和步进等信息。要从处理器封装上的标记信息识别一款处理器,请使用处理器技术指标查询器
这下问题解决了,笔者在这个过程中学到了不少都西,关于Cpuid指令的使用,也在网上搜到了不少资料,在这里稍稍总结以下,供大家参考:
