Forums - Using DSP with Native APIs

Hello,

I am trying to use DSP for inceptionV3 model with native APIs, and I have some problems.

First, I confirmed the NativeCpp example code working well in my Android project. Then, I modified the example codes (main.cpp, CreateUserBuffer.cpp, Android.mk, etc.) a bit to use DSP.

To do that, I made input .raw images from 32bit to 8-bit, and changed Android.mk to include .so files for DSP. Also, zdl::DlSystem::Runtime_t runtime is set to DSP, and size of user buffer is changed by editing elementsize from 4(float) to 1(unsinged char).

When printing the logs, I confirmed input bufSize is the same as input file size (299x299x3 = 268203), output buffer size was 1008, which are 1/4 of buffer size when running on CPU/GPU. Of course I checked whether "zdl::SNPE::SNPEFactory::isRuntimeAvailable(zdl::DlSystem::Runtime_t::DSP)" returns True.

However, I got runtime error for the "snpe->execute(inputMap, outputMap);" line.

So, could you give me some sample codes or advices for this?

My test circumstance is SDM845(Galaxy S9) and some printed logs are attached below.
