纯C版本只是当成参考实现，目前只做了 arm neon 优化，其他架构还没有。。

但是SIMD优化是基于纯C实现的，SIMD的优化倍数是有限的，C的效率不高SIMD并行优化之后效率本身也是有限的，同时我在ARM V7的单核CPU上编译测试了TensorFlow和NCNN，均开了neon优化，squeezenet demo的性能差距也是蛮大的

能否提供一下你们在ARM参考平台上TensorFlow和NCNN测试的性能对比数据？？ 谢谢！

我测试了海思安防芯片，HI3536平台（4核A17 1.4Ghz），开一个核心450ms。已经不错了

纯C实现是没有优化的，速度可能比 arm 优化版本慢10倍以上。。
