TDA2E: How to realize TIDL model switching without reloading the whole Chain?

Part Number: TDA2E


Hi,

I need to run two (OD and SemSeg) TIDL models alternatively. However, it takes too long to reload the whole chain.

Besides, I found the 'ALGORITHM_LINK_OBJ_MAX' parameter. Does that mean I can load two models on one EVE, and switch while the chain running?

    As long as you have enough resource to allocate for both chains, you can create them statically and feed data to one of the chains at a time.

    Regards,

    Hi Stanley
    I'm trying to restart tidl_OD usecase without create & delete repeatedly.
    However, the chain can be started (chains_tidlEVE_StartAPP) and then stop (chain_tidlEVE_StopAPP) correctly, but can not be restarted again by chains_tidlEVE_StartAPP. 
    Corresponding code and log are shown below.
    Void chains_tidlEVE_StartAPP(chains_tidlODAppObj *pObj)
{
chains_tidlEVE_Start(&pObj->ucObj);
Chains_prfLoadCalcEnable(TRUE, FALSE, FALSE);
}

Void chains_tidlEVE_StopAPP(chains_tidlODAppObj *pObj) 
{
 chains_tidlEVE_Stop(&pObj->ucObj); 
 Chains_prfLoadCalcEnable(FALSE, TRUE, TRUE); 
}

    log:

    The chain doesn't support "restart" from STOP state.

    Once in STOP state, it has to go to "Delete" next.

    After "Delete", you can start the chain again by "Create" and "Start".
