Query Text:
Part Number: TDA2 SD card boot, run ALG_TIDL on the DSP, what should you pay attention to? How to set “ Void chains_tidlDsp_SetAppPrms(chains_tidlDspObj *pUcObj, Void *appObj) ”like this : Void chains_tidlDsp_SetAppPrms(chains_tidlDspObj *pUcObj, Void *appObj) { chains_tidlAppObj *pObj = (chains_tidlAppObj*)appObj; /* Null Source Parameters */ setNullSrcPrm(pObj); /* TIDL Pre Process */ pUcObj->Alg_tidlpreprocPrm.outPad = TIDL_MAX_PAD_SIZE; pUcObj->Alg_tidlpreprocPrm.numOutputQueues = NUM_PIPELINES; pUcObj->Alg_tidlpreprocPrm.procMode = TIDLPREPROC_LINK_PROCMODE_RGBPAD; /* * Set the TIDL algorithm parameters for all the 'NUM_PIPELINES' instances. */ /* TIDL on DSP1 */ pUcObj->Alg_tidl_1Prm.cacheInvInBuf = 1; pUcObj->Alg_tidl_1Prm.cacheWbOutBuf = 1; pUcObj->Alg_tidl_1Prm.pAlgCreateParams = pObj->pAlgCreateParams; //pUcObj->Alg_tidl_1Prm.curCoreId = TIDL_COREID_EVE1;//myz pUcObj->Alg_tidl_1Prm.curCoreId = TIDL_COREID_EVE1; //pUcObj->Alg_tidl_1Prm.currLayersGroupId = TIDL_LAYER_GROUPID_EVE1;//myz pUcObj->Alg_tidl_1Prm.currLayersGroupId = TIDL_LAYER_GROUPID_EVE1; pUcObj->Alg_tidl_1Prm.ocmcAddr = NULL; /* Null Link */ if(TRUE == pObj->enableOutFileWrite) { pUcObj->NullPrm.appCb = dumpOutCb; pUcObj->NullPrm.appCbArg = pObj; } else { pUcObj->NullPrm.appCb = NULL; pUcObj->NullPrm.appCbArg = NULL; } }

Responses:
Hi, Sorry, I did not under stand your question. the above function is used to set app prms for usecase running on dsp. Regards, Anuj

Hi, Anuj Yes, I set app prms for usecase running on dsp, but DSP operation results are wrong . Thanks, Mary

Hi, Actual TIDL alg runs on EVE only i.e. different convolution layers. Regards, Anuj

Hi, Anuj When I chose to run TIDL on eve, the result was correct. When I chose DSP to run TIDL, the result was wrong. I do not know why. For a simple example, when I run TIDL, I use usecase f: TIDL Usecase, and then select "1: DSP" to run the result is wrong, but when I choose "2: EVE", the result is correct. Thanks! Mary

Hi, TIDL running on eve will give the proper result as it does the complete processing there. If you run TIDL on DSP then it will not do the complete processing for different layers so result is not proper. If you want to know the difference in processing of TIDL while running on DSP vs EVE. Then please raise a new thread with a proper subject and proper explanation of your question. Regards, Anuj

Hi, OK, Thanks! Mary

Hi, Please close the thread. Regards, Anuj
