Main repository of the HSA-on-FPGA demonstrator project. The design uses the LibHSA library described by Reichenbach et al. to connect an x86 host CPU via David de la Chevallerie et al.'s PCIe interface to a custom image processing accelerator. All kernels are dispatched according to the HSA Foundation standards.

• Xilinx Virtex-7 VC709 FPGA
• AMD Ryzen CPU
• AMD Carrizo APU
• Intel Haswell CPU

1. Make sure all submodules are correctly initialized
2. Install both custom MIPS compiler toolchains
3. Set the paths to both installed compilers in LibHSA/global_conf.sh (MIPS(32/64)_GCC_PATH)
4. Setup Tapasco with make install

• compile the x86 host program with make software
• create the FPGA bitstream with make hardware

1. setup the Tapasco environment source Tapasco/setup.sh
2. load driver and bitstream tapasco-load-bitstream --reload-driver vc709_bitstream.bit
3. run the host program ./imgproc --operation=GAUSS3x3 image.png

More options of the host program can be explored with ./imgproc --help
