Overall Speed of the AM3354xx

Other Parts Discussed in Thread: AM3354, AM3894

Hi,

we have setup a Embedded Linux system with the AM3354 PRocessor.

The overall speed of the board expecially with graphics is not the best.

How can we check if the Graphics acceleration is enabled.

Another solution would be to change to a more powerfull CPU, but I looks like the AM3354 is the biggest one i the Sitara Line with LCD support.

Hi Berndt,

All AM335X processors have LCD support. Please check http://www.ti.com/product/AM3354/compare to see how different processors compare. About performance, you can see the AM335X benchmarks for Linux SDK 7.0 here: http://processors.wiki.ti.com/index.php/Sitara_Linux_SDK_Kernel_Performance_Guide

Hi Bisher,

Thanks for the reply. As far as i Know,unfortunatly the AM3354 we have, seems to be the CPU with the highest performance that has an LCD support.

The AM3894 has higher performance but not LCD support.

Any other TI CPU that would be easy to migrate to which has a higher performance.

Regards Bernd

As Biser mentioned, the AM437x ("Aegis") also supports LCD output (active-matrix, passive-matrix and RFBI).

The DM814x / AM387x ("Centaurus") and DM816x / AM389x ("Netra") have powerful video features (especially the DM versions), including parallel digital video outputs which afaik can interface directly to active-matrix (but not passive-matrix) LCDs. Unfortunately, these processors are poorly supported, lack mainline linux support (although basic DM816x / AM389x mainline support arrived recently, but no video yet), and TI doesn't really seem to be interested in investing much time in them anymore.

And the AM572x ("Vayu") is expected soon, which is an insanely big chip in comparison to the AM335x (although the exact specs are not yet known), it has three 24-bit digital video outputs and a HDMI output which can apparently all be used simultaneously.
