To allow portability, various modifications to the target system and to incompatible interfaces were made. The modifications requiring the most time were to the general program management software in the source system and to the load module format in the target system. There were two portings to different architectures: in the first case, porting was achieved with modification of less than 10% of the source system's code; in the second case, less than 5% modification was needed. The authors compare the two projects, and consider the results of the two porting attempts. They examine possible areas where the CTRON specifications can be enhanced to increase the portability between Extended OSs.<<ETX>>","PeriodicalId":275803,"journal":{"name":"Proceedings [1992] The Ninth TRON Project Symposium","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130900372","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This C compiler is designed for the TLCS-90000/TX series microprocessors. For the C compiler, unique optimizing methods for the TRON architecture are used in the routines for optimization of intermediate language and code generation, in addition to the traditional global optimizing methods, such as copy propagation, loop optimization and register calling convention. Thus the compiling performance was improved. The unique features of the TRON architecture are: chained addressing mode, and the ACB and SSTR instructions. Finally, the performance of the optimizing compiler is evaluated in the terms of the execution time and object code size.<<ETX>>","PeriodicalId":275803,"journal":{"name":"Proceedings [1992] The Ninth TRON Project Symposium","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133582789","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The introduction of design diversity into multiple system layers improves system reliability. However, its enormous costs makes it impractical. The authors solve this problem through the fact that the TRON Project standardization approach to achieve compatibility among systems is same as that of the design diversity approach. In order for the MLDD architecture to be effective in improving system reliability, a probability of a coincident error, that is, two or more independently developed implementations failing on the same input, must be low. A low coincident error rate can be achieved by using sufficiently high quality development procedures for real-life applications and different testing methods for developing multiple implementations.<<ETX>>","PeriodicalId":275803,"journal":{"name":"Proceedings [1992] The Ninth TRON Project Symposium","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127982152","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
