performance using accelerators in a computer system. In this study, Cube-1 processor is designed and implemented to realize a high-performance and low-power computer system, which consist of a CPU (Geyser-Cube) and three accelerators (CMA-Cubes). The programming for a CMA-Cube accelerator needs to perform complicated controls efficiently, that are the synchronization between accelerators, the data transfer to an accelerator, and the cooperation with the host CPU Geyser-Cube which performs input /output and control the whole system. This paper describes execution environment in which OpenCL is used to control the CMA-Cube accelerator. OpenCL is implemented for CMA-Cube and the framework of OpenCL API provides CMA-Cube to a user program. Since timing control of synchronization is covered with OpenCL, the programmer does not need to write the execution control at a low level. Furthermore, in order to realize OpenCL for CMA-Cube, the resource management mechanism of CMA-Cube is added to the embedded OS and the task scheduler is realized in order to calculate taking the synchronization between accelerators. The framework for efficiently executing CMA-Cube has been provided only by the increase in about 3% of execution time.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"10","bibliographic_titles":[{"bibliographic_title":"研究報告システムソフトウェアとオペレーティング・システム（OS）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2012-04-30","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"2","bibliographicVolumeNumber":"2012-OS-121"}]},"relation_version_is_last":true,"weko_creator_id":"10"},"created":"2025-01-18T23:35:53.302341+00:00","id":81847,"links":{}}
