    1919due to the design and fabrication costs.
    2020Nowadays Field Programmable Gate Arrays (FPGA), like Virtex5 from Xilinx and Stratix4 from Altera,
    21 can implement a SoC with multiple processors and several coprocessors for less than 10K euros the piece.
    22 In addition, High Level Synthesis (HLS) becomes more mature and allows to automize design
    23 and to decrease drastically its cost in terms of man power. Thus, both FPGA and HLS tends to spread over
    24 HPC for small companies targeting low volume markets.
