AM5728: How to use GPU, DSP, BB2D,EVE and IPU processing blocks ?

rohit yadav

Part Number: AM5728

We are using a custom board based on AM5728 and running VOIP application software on it.

We are facing some issues, seems to be related to processing power, like delayed rendering of GUI, audio video out of sync etc.

We are currently using CPU cores only (Cortex A15). Therefore, CPU usage goes upto 80-90% during video call.

Since there are other additional cores available on the SoC like GPU, Cortex M4 IPUs, DSP, BB2D and Video Processing Engine (IVA subsystem). We are exploring strategies to leverage these resources effectively and offload CPU.

How can we use these additional cores ? Any tools available in SDK ?

Any suggestions for offloading CPU tasks to these alternative cores would be greatly appreciated.

Hello Rohit,

Unfortunately multimedia and the EVE cores have been deprecated in the last couple of SDKs (8.2 & and 9.2).

The best solution would be for you to look at the SW in SDK 6.03 as an example and you can reference the code and examples there as a guideline. Keep in mind this SDK is old so there is not much technical support for most of the examples. They are there in an as-is state.

Also refer to the TRM and other available collaterals, you could also look for other questions on this Forum.

Best,

Josue

Hello Josue ,

We were looking to upgrade to SDK 9.2. Could you elaborate what all is deprecated esp around multimedia ?

We are using the AM5728 board, whereas EVE are available on 5729 and 5749 , I believe.

Hi Josue Zamitiz-Ayala,

I am from Same team as Rohit and as we were discussing and trying out multimedia in SDK 6.03. We had the following query too:

Wrt usage of the internal processors , we would like to know what tools are available to assess the usage of other processors. Like gstreamer uses IVA-HD . How can this be measured ??

Please share some insights.

Hello Himani,

Can you elaborate what you mean by:

There are many example applications included in the 6.03 RTOS SDK here--> https://software-dl.ti.com/processor-sdk-rtos/esd/AM57X/06_03_02_08/exports/docs/rtos/Examples_and_Demonstrations.html
and for IVA-HD you can see more information here --> https://software-dl.ti.com/processor-sdk-linux/esd/docs/06_03_00_106/linux/Foundational_Components_Multimedia_IVAHD.html

This begs the comment that many of the features of 6.03 have been deprecated/de-scoped so technical support for these ranges from very little to none.

Josue
