Bad performance on Hi3516dv300

[ztianlin]

Hi~I have tested your pre-trained Bi-Real Net (18-layer) on Huawei Mate30 Pro and I got an inference time of 20ms which was nice. However, when I built dabnn on Hi3516dv300 (armv7, with NEON open) and ran the same model with net_test, I got an inference time of 2000ms, could you please help me with this "bad performace"?

To reproduce this result: 1.Use the corresponding toolchain file to build dabnn. (Here is my CMAKE_CXX_FLAGS)

SET(CMAKE_CXX_FLAGS " -mfloat-abi=softfp -mfpu=neon-vfpv4 -mcpu=cortex-a7 ${CMAKE_CXX_FLAGS}" )

2.Test the generated net_test on Hi3516dv300 and here is what I got:

/mnt/output/tianlin/dabnn_test/bin # ./net_test Running main() from /home/tianlin/dabnn/third_party/googletest/googletest/src/gtest_main.cc [==========] Running 4 tests from 1 test suite.
