The unit CPUID offers routines to access the CPU identification tags. By using CPUID you can access the type of the CPU, its serial number, the vendor, the CPU signature and other specific information about the processor. In addition, CPUID contains a function which allows to generate a (for practical purposes) unique ID, and a function to check the validity of a foreign ID. Further, you can measure the actual CPU frequency. See the online help pages for detailed information on the unit CPUID.
The unit CPUID is part of the SDL Component Suite.
| CPUInfo |  Shows how to retrieve information about the CPU using the unit CPUID). Note that the calculated CPU-ID can be used to identify a particular computer. Sources of the sample program are included (Delphi 6). |
