Implementation results show that the generic virtual channel allocator (VA) and the generic switch allocator (SA) of a router consume large amount of area and power. In this paper, after a careful study of the working principle of a VA and the utilization statistics of its arbiters, opportunities to simplify the generic VA are identified. Then, the deadlock problem for a combined switch and virtual channel allocator (SVA) is studied. Next, the impact of the VA simplification on the router critical paths is analyzed. Finally, the generic architecture and two low-cost architectures proposed (the look-ahead, and the SVA) are evaluated with a cycle-accurate network simulator and detailed VLSI implementations. Results show that both the look-ahead and the SVA significantly reduce area and power compared to the generic architecture. Furthermore, cost savings are achieved without performance penalty.<\/jats:p>","DOI":"10.1155\/2009\/415646","type":"journal-article","created":{"date-parts":[[2010,3,15]],"date-time":"2010-03-15T15:30:18Z","timestamp":1268667018000},"page":"1-10","source":"Crossref","is-referenced-by-count":2,"title":["Low-Cost Allocator Implementations for Networks-on-Chip Routers"],"prefix":"10.1155","volume":"2009","author":[{"given":"Min","family":"Zhang","sequence":"first","affiliation":[{"name":"Department of Electronic Engineering, The Chinese University of Hong Kong, Shatin, Hong Kong"}]},{"given":"Chiu-Sing","family":"Choy","sequence":"additional","affiliation":[{"name":"Department of Electronic Engineering, The Chinese University of Hong Kong, Shatin, Hong Kong"}]}],"member":"311","reference":[{"key":"2","doi-asserted-by":"publisher","DOI":"10.1109\/MM.2007.4378787"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1109\/MDT.2005.103"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1109\/TVLSI.2006.878263"},{"key":"12","doi-asserted-by":"publisher","DOI":"10.1109\/TCAD.2006.882474"},{"key":"13","doi-asserted-by":"publisher","DOI":"10.1049\/iet-cdt:20050068"},{"year":"2004","key":"14"}],"container-title":["VLSI Design"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/archive\/2009\/415646.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/archive\/2009\/415646.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/archive\/2009\/415646.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2020,12,8]],"date-time":"2020-12-08T20:14:27Z","timestamp":1607458467000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.hindawi.com\/journals\/vlsi\/2009\/415646\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2009,3,15]]},"references-count":6,"alternative-id":["415646","415646"],"URL":"https:\/\/doi.org\/10.1155\/2009\/415646","relation":{},"ISSN":["1065-514X","1563-5171"],"issn-type":[{"type":"print","value":"1065-514X"},{"type":"electronic","value":"1563-5171"}],"subject":[],"published":{"date-parts":[[2009,3,15]]}}}
