# Caffe-HRT
[](LICENSE)
Caffe-HRT is a project that is maintained by **OPEN** AI LAB, it uses heterogeneous computing infrastructure framework to speed up [Caffe](http://caffe.berkeleyvision.org/) and provide utilities to debug, profile and tune application performance.
The release version is 0.5.0, is based on [Rockchip RK3399](http://www.rock-chips.com/plus/3399.html) Platform, target OS is Ubuntu 16.04. Can download the source code from [OAID/Caffe-HRT](https://github.com/OAID/Caffe-HRT)
* 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](https://github.com/ARM-software/ComputeLibrary).
* Caffe is a fast open framework for deep learning. See also [Caffe](https://github.com/BVLC/caffe).
### Documents
* [Installation instructions](acl_openailab/installation.md)
* [User Manuals PDF](acl_openailab/user_manual.pdf)
* [Performance Report PDF](acl_openailab/performance_report.pdf)
* [Accuracy Report PDF](acl_openailab/accuracy_report.pdf)
### 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
# Release History
