Как получить информацию о процессоре?
01.01.2007
О процессоре можно на любом уровне (приложении или драйвере) получить информацию с помощью команды(машинной) CPUID(386+):
Например(Вставка на асм в языке Паскаль):
{Получить тип процессора}
asm
mov eax,0
cpuid {Или db 0Fh, 0A2h}
{Теперь регистры EBX:ECX:EDX содержат строку "Genu-inel-ntel" (например)}
end;
Передать в Паскаль содержимое регистров можно, например, так:
var
EBXstr,ECXstr,EDXstr: string[5];
begin
asm
mov eax,0
cpuid
mov dword ptr EBXstr+1,EBX
mov byte ptr EBXstr,4
mov dword ptr ECXstr+1,ECX
mov byte ptr ECXstr,4
mov dword ptr EDXstr+1,EDX
mov byte ptr EDXstr,4
end;
writeln(EBSstr,ECXstr,EDXstr);
