# Sample code of Python extension module using DPC++ (Data Parallel C++)  

### Description:  

This project demonstrates how to write a Python extension module with [DPC++](https://software.intel.com/content/www/us/en/develop/tools/oneapi/components/dpc-compiler.html#gs.8eyara). The Python extension will take an OpenCV image stored in a Numpy array and do image processing. The actual image processing code is using DPC++ kernel and the rest is written in standard C++ code.  

DPC++ is a Clang based compiler developed by Intel which includs Khronos [SYCL](https://www.khronos.org/sycl/) extension and Intel specific SYCL extensions. **It enables seamless heterogeneous programming and can support not only CPU but also integrated GPU, FPGA and more to come**.  

* Result example

### Prerequisites:

- DPC++ compiler (from oneAPI Base Toolkit 2021.3)

### How to build and run:

```sh

build.sh

```

 * `python_dpcpp_module.so` will be generated.

```sh

python3 test.py

```

### Note:  

Tested on Ubuntu 20.04.
