This leap in performance is desired to be ported to computerized numerical controls. However, in order to profit of the benefits multi-core processors can bring, the software has to be tailored to real parallel execution. In this paper a concept is proposed for partitioning numerical control software functions for being concurrently executed on multi-core systems. Specifically, the interpreter and the cutter radius compensation modules have been analyzed for devising a feasible parallel architecture. The parser algorithm has been implemented following the proposed scheme in a thread-based approach. Experiments were conducted under a real time Linux kernel extension utilizing the PREEMPT_RT patch. The results were compared against its serial version in terms of execution times to validate the concept.", "issn" : "2212-8271", "doi" : "http://dx.doi.org/10.1016/j.procir.2015.12.021", "bibtexKey": "Vivanco2016864" } , { "type" : "Publication", "id" : "https://puma.ub.uni-stuttgart.de/bibtex/207908a9de6488c702fcde927f25b954e/isw-bibliothek", "tags" : [ "CNC","ISW","Multicore","Parallelization","xkt" ], "intraHash" : "07908a9de6488c702fcde927f25b954e", "interHash" : "dda7cb22d7be3b08660ce2d060f4bbb3", "label" : "Analysis of CNC Software Modules regarding Parallelization Capability", "user" : "isw-bibliothek", "description" : "", "date" : "2016-03-03 09:53:12", "changeDate" : "2016-03-14 15:23:45", "count" : 1, "pub-type": "inproceedings", "booktitle": "Proceedings of the 24th International Conference on Flexible Automation & Intelligent Manufacturing FAIM 2014", "year": "2014", "url": "", "author": [ "Matthias Keinert","Benjamin Kaiser","Armin Lechler","Alexander Verl" ], "authors": [ {"first" : "Matthias", "last" : "Keinert"}, {"first" : "Benjamin", "last" : "Kaiser"}, {"first" : "Armin", "last" : "Lechler"}, {"first" : "Alexander", "last" : "Verl"} ], "pages": "pp. 79-86","abstract": "The software design of current CNC systems is of limited suitability for real parallel execution on multicore systems. Even though CNC systems are rudimentarily designed in a modular way, a good load balancing andtherefore an efficient use of multiple processor cores is not satisfactorily to be accomplished, as the modularization is not sophisticated enough. A parallelization of CNC functions and algorithms would remedy this deficit. Thispaper presents an analysis on which parts of a CNC system show the capability for parallelization.
