| Outline of Final Research Achievements |
We developed a dedicated system to accelerate numerical integrations with multi precision operations. We designed a processor enabling 4/6/8 precision operations and implemented it on a Field-programmable gate array. We also constructed a software library with OpenCL which supports a calculation with high precision. This library enables us to perform a calculation with high precision at high speed on GPUs. Both can be utilized uniformly by our developed compiler system. Applying to our applications, we demonstrated a validity of our system.
