RTOS: TIDL Eve Memory Allocation Insufficient Question

Z.Y Wang

Hi guys,

I met some memory allocation qproblem When i try to use my own TIDL usecase.I wanna use tidl deep learing while extart EVE1 in another thread to run ImagePreProcess,and below is my usecase chains:

When runing this usecase,i'm facing the error:

[EVE1] Assertion @ Line: 160 in tidl/tidlLink_algPlugin.c: NULL != pAlgObj->memRec[cnt].base : failed !!!
[EVE1] Assertion @ Line: 160 in tidl/tidlLink_algPlugin.c: NULL != pAlgObj->memRec[cnt].base : failed !!!

I think the problem is EVE is called twice in the chain, OCMC_RAN memory run out.So in this case how to allocate memory?Please help!

Thanks,

Hi,

Can you modify your usecase and run tidl on 3 eves only and check.

Hi，Anuj

Yes，that works but too slowly,almost 1 frame/second.When TIDL runs in 3 eves ， the EVE1 only consumes 10% while other 3 eves consume 85%.I wanne balance this issue but it seems like OCMC_ADDRESS not big enough to allocate.So is there any way make this usecase work?If not ，in this case how to speed up.

Thanks,

Hi,

OCMC region is limited and your both algo is using OCMC from EVE1.

So there is no workaround here.

You can run either tidl or ImagePreProcess on a single EVE core.
