TDA2EXEVM: how to match network results between caffe-jacinto(float) and TIDL(int8)

Part Number:TDA2EXEVM

I tried to match the results layer by layer between caffe-jacinto and TIDL. But the results are quite different.

how to use quantization params to get float point weights, bias, inData and outData? the TIDL layer's output is int8 or uint8?

int32_t weightsQ;
int32_t biasQ;
int32_t inDataQ;
int32_t outDataQ;
int32_t interDataQ;
