Graphics Device Interface Performance Test (Windows CE 5.0)
The Graphics Device Interface Performance Test assesses the performance of common display operations. This test can help you with the following design and development tasks:
- Optimize a display driver.
- Decide which display driver meets your performance requirements.
- Identify which operations to perform in hardware instead of software.
- Decide which hardware functionality to support in a display chipset.
The Microsoft® Windows® CE Test Kit (CETK) provides four scripts that you can use with the Graphics Device Interface Performance Test. You can also write a custom script to test a specific function or mimic an application to help you tune the performance of your target device. For information about writing a script and information about the scripts that the CETK provides, see Script Development for the Graphics Device Interface Performance Test.
The following table shows the software requirements for the Graphics Device Interface Performance Test.
| Requirements | Description |
|---|---|
| Tux.exe | Tux test harness, which is required for executing the test. |
| Kato.dll | Kato logging engine, which is required for logging test data. |
| Tooltalk.dll | Application required by Tux.exe and Kato.dll. Handles the transport between the target device and the development workstation. |
| Gdip.exe | Executable file for the test. |
| Allropsscript.txt, Iescript.txt, Rdpscript.txt, or Srccopysizes.txt | Script file. You can also write a custom script file. |
This test requires that you include a display driver in the OS design that is appropriate for the display hardware on your target device.
Note When you run the Graphics Device Interface Performance Test, the CETK temporarily copies files to the root directory of the target device. Before running the test, verify that there is at least 0.4 megabytes (MB) of free space in the root directory of the target device. If there is not sufficient space in the root directory of the target device, the test cannot run.
