RTOS/TDA2PXEVM: Increasing the FPS of TIDL_OD usecase

George Jose67

Part Number: TDA2PXEVM

Tool/software: TI-RTOS

Hi,

I am using Vision SDK 3.06. I am trying to increase the FPS for TIDL_OD usecase.

1) Are variables TIDL_OD_FPS_OPPHIGH, and TIDL_OD_FPS_OPPNOM redundant in this Vision SDK release? FPS is set directly from the SD card right?

2) Should NUM_PIPELINES be same as the number of EVEs?

3) How can I overclock the EVEs and DSPs and is it safe to perform this?

4) Can any change numCh or numBuffsPerCh in any of the links help in increasing FPS?

5) What could be the other optimizations to increase the FPS?

Regards

George

Hi,

Please fine your answers below

1) OOP_HIGH with run all CPUs at higher frequency and OOP_NOM will run at lower freq.So even if you put higher FPS from SD card and Using OPP_NOM, you wont get that much higher FPS.(With OPP_HIGH and Release binaries you should get more than 20 FPS)

2) Yes.

3) By Using OPP_HIGH, you are doing the same.

4) Yes numCh and numBuffsPerCh will decide the FPS.

5) I you are getting arounf 20-25 FPS with OPP_HIGH and release binary then there is no further optimization you can do.

Hi,

I am seeing OPP_HIGH frequency for EVE as 650 MHz. Can I overclock it to 900MHz and DSP to 1000MHz? If so, what changes should I make?

Hi,

in OPP_HIGH we run all cores at max clock rate.

Hi George,

TI doesn't recommend running any CPU at a frequency that is outside the range mentioned in Data Manual.
Hence I would not recommend overclocking DSP and EVE.
However in case you still want to overclock you need to make DPLL changes in SBL.
The file to modify is PROCESSOR_SDK_VISION_03_06_00_00\ti_components\drivers\pdk_01_10_02_07\packages\ti\boot\sbl_auto\sbl_lib\src\tda2xx\sbl_lib_tda2xx_prcm_dpll.c

Hi,

Please close the thread by verifying answer if it answers your query.
After overclocking EVE and DSP, you might get around 15 FPS on TDA2px platform as it has 2 EVEs only with release binaries

Hi,

I haven't heard back from you, I'm assuming you were able to resolve your issue.
If not, just post a reply below (or create a new thread if the thread has locked due to time-out).
