Ok, sebelum kita mulai nyalakan dulu program tutorialnya….

reading DVD……

function TForm1.GetCpuSpeed: Extended;
var
t: DWORD;
mhi, mlo, nhi, nlo: DWORD;
t0, t1, chi, clo, shr32: Comp;
begin

while t = GetTickCount do begin end;
asm

DB 031H
mov mhi,edx
mov mlo,eax
end;

while GetTickCount < (t + 1000) do begin end;
asm

DB 031H
mov nhi,edx
mov nlo,eax
end;
chi := mhi; if mhi < 0 then chi := chi + shr32;
clo := mlo; if mlo < 0 then clo := clo + shr32;

t1 := chi * shr32 + clo;
Result := (t1 – t0) / 1E6;
end;

procedure TForm1.Button1Click(Sender: TObject);
begin

//menampilkan  kecepatan prosesor
Label1.Caption := FloatToStr(GetCpuSpeed) + ‘ MHz’;
end;
