Using data parallelism, this instruction set processes mass data faster than the scalar. Therefore it is used to optimize multimedia or mathmatic processing. There are researches to analyze programs to vectoize with SIMD instruction set, that make compilers to enable to generate SIMD codes. By the way, SIMD instruction set cannot select instructions for every packed data. Accordingly the complex control flow which includes conditional branches or loops are not treated for optimization with the instruction set. However if they became applicable to parallelize with that instruction set, more programs are expected to be optimized. In this paper, the method vectorizing the programs containing complex control structure with SIMD instruction set is proposed.It was implemented with COINS compiler infrastructure and converted some programs from scalar to vector. They achieved from 1.19 to 12.3 times speedup on PowerPC's SIMD instruction set.","subitem_description_type":"Other"}]},"item_3_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"72","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌プログラミング（PRO）"}],"bibliographicPageStart":"62","bibliographicIssueDates":{"bibliographicIssueDate":"2007-03-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"SIG4(PRO32)","bibliographicVolumeNumber":"48"}]},"relation_version_is_last":true,"weko_creator_id":"1"},"created":"2025-01-18T22:49:46.239285+00:00","id":16522,"links":{}}
