I have a couple of benchmarks.
Download GapiDraw (www.gapidraw.com). Copy the contents from the following folders to the PDA:
samples\MFC\WinCE\ARMRel\
samples\Simple\WinCE\ARMRel
[MFC Sample]
This sample tests a combination of small blits and non-sequential memory reads. This will grind to a halt on XScale processors.
Performance on an IPAQ 3630:
Landscape: 175 sprites
Portrait: 130 sprites
Performance on an Toshiba E740:
Landscape: 50 sprites
Portrait: 100 sprites
[Simple]
This demo copies and rotates a large bitmap to the display. The copy is done in a cache-optimized way.
Performance on an IPAQ 3630:
Landscape: 23 ms / frame
Portrait: 23 ms / frame
Performance on an Toshiba E740:
Landscape: 30 ms / frame
Portrait: 30 ms / frame
Try these on the 310 and post the results...
