sycl-fpga-vector-add

This project provides the following:

• A basic vector algebra implementation in SYCL and code for comparing with a multithreaded implementation
• An FPGA vector add geared towards use with Intel's OneAPI
• CMake examples of compilation for FPGA emulation and bitstreams tested with OneAPI 2021.2

Compilation

Example (from within a directory inside of the repo)

. /tools/intel/oneapi/1.0/setvars.sh
#Source a newer CMake than the default one installed
. /tools/misc/env/cmake_build.sh
mkdir oneapi_build && cd oneapi_build
cmake .. -DCMAKE_TOOLCHAIN_FILE=cmake/oneapi-toolchain.cmake -DUSE_FPGA_EMULATOR=1 -DUSE_SYCL=1

CMake Flag Options

• USE_SYCL In order to compile with SYCL support (basically required).
• USE_CPU_HOST In order to compile to target the host device.
• USE_FPGA_EMULATOR In order to compile to target the FPGA emulator.
• USE_FPGA_REPORT In order to compile to target the FPGA emulator and generate a static report.
• USE_FPGA_PROFILING In order to compile to target FPGA with vTune profiling enabled.
• Specify none of the above options (except for USE_SYCL) in order to generate a bitstream for FPGA.

Scripts

The scripts directory contains three example scripts that iterate over all the options (CPU_HOST, EMULATOR, etc.) to 1) create appropriate build directories, compile, and package a build directory. You might want to run one or two of these scripts just to see how the process works with CMake. Note that bitstream generation will take a while to complete.

. /tools/intel/oneapi/1.0/setvars.sh
#Source a newer CMake than the default one installed
. /tools/misc/env/cmake_build.sh
[sycl-testing]$ ./scripts/run_cmake_build.sh
