Ladder diagram (ladder logic) is widely used to PLCs. The idea of the speed-up method is simple: (1) We convert ladder diagrams to sequence instructions. (2) Sequence instructions have many logic devices which have values either 0 or 1. Assume that a logic device Mi has the value 0 (1), we can reduce some subsequent logical instructions which involves Mi. We pregenerate two reduced sequences; one is the codes in which Mi is assigned to 0, the other is the codes in which Mi is assigned to 1. (3) We connect them using a CJ (conditional jump) operation. Preliminary experimental results show that the number of executed instructions is reduced by 3.0 ～ 4.7 percent. Although the naive method increases the number of total instructions by 6.3 times. By eliminating duplicate instructions, we prevent the rate of increase by 2.9 times.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告システムとLSIの設計技術（SLDM）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2019-03-10","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"47","bibliographicVolumeNumber":"2019-SLDM-187"}]},"relation_version_is_last":true,"weko_creator_id":"44499"}}
