| Abstract(in English) | In recent years, many kinds of scientific application programs, such as Fluid analysis, Feynman loop integrals and conjugate gradient (CG) method for calculation of the scattering amplitudes, require high-precision floating-point operations. We have proposed a reconfigurable accelerator HP-DSFP with digit serial floating point unit so as to accelerate scientific computation by using multiple precision floating point operations. From the evaluation results, HP-DSFP processor reduced the execution time of FFT, Loop Integrals, and CGM to 7.4%, 9.2%, 21.5% respectively, compared to the CPU with multiple-precision floating-point C library MPFR. |
