AM387x and tiler

Rogerio Almeida

I was just looking through the DM814x PSP wiki which has instructions on how to enable the tiler in the kernel config. I also saw EZSDK is 5.04 alpha.

Am I correct that if my customer uses one of the supported formats, they can access frame buffer memory in a 16x16 tiled fashion?

I’ve been searching the forum for examples of ‘how to use the tiler’, so far nothing. Any pointers?

Hello,

I am not familiar with AM387x and TILER, but you could check in TRM ( sprugz7b.pdf chaper: DMM/TILER) and http://processors.wiki.ti.com/index.php/DM814x_AM387x_PSP_User_Guide#TILER

Hope this helps.

Best Regards,

Margarita

Margarita,

I've seen this page and it describes how to enable it. I'm looking for example code of it being used. Any Centaurus code (AM387x, DM814x, C6A814x) would suffice. Do you know of any Tiler examples?

Thanks.

Hi Marc,

If you have HDVPSS software, the demo application for DEI demonstrate the use of TILER memory.

Please check if that helps you.

DEI demo application is available in HDVPSS package at hdvpss_01_00_01_38\packages\ti\psp\examples\common\vps\m2m\m2mDeiScale\src\M2mDeiScale_test.c

There are 2 macros that configure the application to use TILED memory at input/output. Please enable the required macro, rebuild and test.

DEI_IN_MEM_TYPE

and

DEI_VIP_OUT_MEM_TYPE

Thanks,

Sujith
