Abstract (in Japanese) (See Japanese page) 
(in English) FPGAs are one of hopeful candidate of accelerator for scientific computing in near future. There are many attempts in various area of science, to build custom numerical pipelines on FPGAs to realize high-performance and low-power computing platform. However, FPGA design basically requires HDL design skills, that is not familiar with scientists in physics, life science and other field of sciences. The aim of this research is to find out an effective way to design an accelerator for scientific computation using high-level synthesis (HLS) tools, that support floating– point computation. In this report, solvers diffusion equation on 2-D orthogonal grid had implemented in both HDL and HLS as benchmark, with different ways to give boundary conditions and different methods of numerical inte- gration. As the result, the resulting circuit synthesized by Vivado HLS had reasonable size and performance. While Vivado HLS requires a little care about way of coding in C, users can try pipelining or inline expansion of loops and functions easily. Thus, it is reasonable to say that using HLS to implement kernels of scientific computation can be
an effective solution.
