I am working on comparing inference time of neural networks with ARM-CL on HiKey board ARM Mali-G72 MP12. First, I obtained inference time without passing real image with Dummy Accessor in ARM-CL. Then, I obtained inference time by passing real images with Image Accessor. After comparison, the inference time with real image was lesser than that with the Dummy Accessor. Could you please help me understand why the inference time with Image Accessor is less than that of Dummy Accessor?
