the automobile control system is advancing to achieve more safety, comfort and fuel efficiency. Accordingly, control systems need performance enhancement on microprocessors. However, the improvement of clock frequency has been limited by power consumption and the performance of a single-core processor which controls power has reached the limits. For these factors, multi-core processors will be used for automotive control system. However, it is difficult to parallelize source code and attain speedup on multi-core processors. Recently Model-based Design has been used for developing automobile systems because of elimination time of development and improvement of reliability. However, auto-generated-code from Model-based Design has been functioned on only single core processor so far. This paper proposes a parallelization method of engine control C codes for a multi-core processor developed by Model-Based Design. The engine control C code which composed of only conditional branches and arithmetic assignment statements and are difficult to parallelize have been parallelized automatically and succeeded to attain performance improvement on RP2 and V850E2R. Maximum 1.9x speedup on two cores and 3.76x speedup on four cores are attained. It is confirmed that parallelization of engine control C code developed by model based design on multi-core processor is possible.","subitem_description_type":"Other"}]},"item_18_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"113","bibliographic_titles":[{"bibliographic_title":"組込みシステムシンポジウム2013論文集"}],"bibliographicPageStart":"104","bibliographicIssueDates":{"bibliographicIssueDate":"2013-10-09","bibliographicIssueDateType":"Issued"},"bibliographicVolumeNumber":"2013"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"id":95451,"updated":"2025-01-21T13:49:43.421568+00:00","links":{},"created":"2025-01-18T23:42:32.657186+00:00"}
