**MiAI Compute Engine** is a deep learning inference framework optimized for
mobile heterogeneous computing platforms. The design is focused on the following
targets:
* Performance
  * The runtime is highly optimized with NEON, OpenCL and Hexagon. Except for the
    inference speed, the initialization speed is also intensively optimized.
* Power consumption
  * Chip dependent power options are included as advanced API.
* Memory usage and library footprint
  * Graph level memory allocation optimization and buffer reuse is supported.
* Model protection
  * Model protection is one the highest priority feature from the beginning of 
    the design. Various techniques are introduced like coverting models to C++
    code and literal obfuscations.
* Platform coverage
  * A good coverage of recent Qualcomm, MediaTek, Pinecone and other ARM based
    chips. CPU runtime is also compitable with most POSIX systems and
    archetectures with limited performance.

## Getting Started
* [Introduction](docs/getting_started/introduction.rst)
* [How to build](docs/getting_started/how_to_build.rst)
* [Create a model deployment file](docs/getting_started/create_a_model_deployment.rst)

## Performance
[MiAI Compute Engine Model Zoo](http://v9.git.n.xiaomi.com/deep-computing/mace-models) contains
several common neural networks models and built daily against a list of mobile
phones. The benchmark result can be found in the CI result page.

## Acknowledgement
MiAI Compute Engine depends on several open source projects located in
[third_party](mace/third_party) directory. Particularly, we learned a lot from
the following projects during the development:
* [Qualcomm Hexagon NN Offload Framework](https://source.codeaurora.org/quic/hexagon_nn/nnlib): the Hexagon DSP runtime
  depends on this library.
* [TensorFlow](https://github.com/tensorflow/tensorflow),
  [Caffe](https://github.com/BVLC/caffe),
  [SNPE](https://developer.qualcomm.com/software/snapdragon-neural-processing-engine-ai),
  [ARM ComputeLibrary](https://github.com/ARM-software/ComputeLibrary),
  [ncnn](https://github.com/Tencent/ncnn) and many others: we learned many best
  practices from these projects.

Finally, we also thank the Qualcomm, Pinecone and MediaTek engineering teams for
their helps.
