CaffeOnACL

License

CaffeOnACL is a project that is maintained by OPEN AI LAB, it uses Arm Compute Library (NEON+GPU) to speed up Caffe and provide utilities to debug, profile and tune application performance.

The release version is 0.4.0, is based on Rockchip RK3399 Platform, target OS is Ubuntu 16.04. Can download the source code from OAID/CaffeOnACL

  • The ARM Computer Vision and Machine Learning library is a set of functions optimised for both ARM CPUs and GPUs using SIMD technologies. See also Arm Compute Library.
  • Caffe is a fast open framework for deep learning. See also Caffe.

Arm Compute Library Compatibility Issues :

There are some compatibility issues between ACL and Caffe Layers, we bypass it to Caffe's original layer class as the workaround solution for the below issues

  • Normalization in-channel issue
  • Tanh issue
  • Softmax supporting multi-dimension issue
  • Group issue

Performance need be fine turned in the future
