Hardware Platform

Device	System	CPU-Family	CPU-Num	Freq
RK3288	Android 5.1	Cortex-A17	4	1.8GHz
Qualcomm820	Android 6.0	Kryo	2+2	2.15GHz/1.6GHz
Mi5	Android 7.1.2	Kryo	2+2	1.8GHz/1.3GHz
Hi3519	Linux 3.18.20	Cortex-A17	1	1.2GHz

Runtime Environment

1.Using the cpu working in performance model.  

echo performance > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor

2.Loop a hundred times to take the minimum value of Inference time-consuming.

User Guide

1. Build the benchmark demo

build demo for Linux-x86

./build.sh linux

build demo for Android

./build.sh android

2. How to run the executable files.

If you build demo for linux success,and want to run the benchmark demo.

$ cp ./models/classification/squeezenet.param  ./build-linux/install/bin/
$ cp ./models/classification/squeezenet.bin  ./build-linux/install/bin/
$ cd ./build-linux/install/bin/
$ ./ncnn_classify squeezenet.param squeezenet.bin 227 227 1 1

Demo running params:

./ncnn_classify <ncnn-param-file> <ncnn-model-bin-file> <input-width> <input-height> <loops-num> <threads-num>

Example:

bug1989@ubuntu:~/ncnn-benchmark/build-linux/install/bin$ ./ncnn_classify squeezenet.param squeezenet.bin 227 227 10 2
