The way to achieve this goal is to define parallel programmable engines. The concept of FP System, introduced by John Backus in 1978, is used to define a high level architectural environment: Backus-Connex Parallel Functional Programming System. The functional forms of FP Systems correspond perfect with the four types of parallelism derived for ConnexArray™ from the Kleene's computational model. The paper defines the BC programming environment, describes its implementation in Scheme and presents its use for developing real applications for functional nano-devices.","PeriodicalId":403202,"journal":{"name":"CAS 2011 Proceedings (2011 International Semiconductor Conference)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124517065","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}
