(1) To describe the operating system (OS) of educational computer TaC and show the implementation of an OS to students. (2) To show C-- language compiler to students as an implementation of a compiler. (3) Students can learn C-- language at short time. And they can use it to program embedded systems. To achieve these purposes, we designed a compact language without complicated syntax to beginners. Then, we implemented the small compiler which students can refer to as an implementation. To be downsized, the compiler performs parsing and code generation at the same time without syntax tree. However, we understood that a compact implementation was not necessarily easy to read it. Therefore we introduced a syntax tree and separated parsing and code generation to independent modules. Finally we described the TaC operating system by using C-- language, and we confirmed that we could use it as a practical system description language. The specification of C-- is smaller than that of C language. So students can easily understand it. On the other hand, C-- language has ability to describe an OS and a compiler. However, it became clear that there were the insufficient points such as that arrays could not be declared in a function.","subitem_description_type":"Other"}]},"item_3_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"15","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌プログラミング（PRO）"}],"bibliographicPageStart":"15","bibliographicIssueDates":{"bibliographicIssueDate":"2017-06-16","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"3","bibliographicVolumeNumber":"10"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"created":"2025-01-19T00:49:54.711345+00:00","updated":"2025-01-20T04:08:56.518466+00:00"}
