Hello,
we are currently developing a handheld device that will display several
curve plotters with realtime data.
We chose FLTK on top of DirectFB as software plattform and an AVR32
(AP7000) with an 800x480 (WVGA) Display.
Unfortunately the drawing performance on this platform is not fully
satisfying.
(see for Benchmarks with df_dok below)
Therefore we consider to change the Processor to a AT91SAM9263.
My questions therefore:
1) Is there a graphic driver for the accelerator unit of the AT91SAM9263?
2) Has anybody made benchmarks (df_dok) on this Processor (with/without
Acceleration) ?
3) Do you have benchmark results for similar processors? Is there a
database?
Here are my benchmark results (AVR32):
