This paper studies a chip multi-processor (CMP) with smaller processor cores as a means to achieve high aggregate throughput and improved energy efficiency. The benefit of this design approach increases as the number of cores on a chip increases, as enabled by semiconductor process scaling. The feasibility of a processor core 40% of the size of a baseline high performance processor that delivers about 70% of its performance is shown. The CMP populated by smaller cores to fill the same silicon area delivers 2.3 times higher performance in transaction processing represented by TPC-C benchmarks than the baseline processor scaled into the same technology. The CMP also achieves 38% higher energy efficiency."}],"abstractLicenseFlag":"disallow"}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1410001205222061060","@type":"Researcher","personIdentifier":[{"@type":"NRID","@value":"9000020871387"}],"foaf:name":[{"@language":"en","@value":"Asato Akira"}],"jpcoar:affiliationName":[{"@language":"en","@value":"Fujitsu Laboratories Ltd., Japan"}]},{"@id":"https://cir.nii.ac.jp/crid/1410001205222061059","@type":"Researcher","personIdentifier":[{"@type":"NRID","@value":"9000020871392"}],"foaf:name":[{"@language":"en","@value":"Kawaba Motoyuki"}],"jpcoar:affiliationName":[{"@language":"en","@value":"Fujitsu Laboratories Ltd., Japan"}]},{"@id":"https://cir.nii.ac.jp/crid/1410001205222061058","@type":"Researcher","personIdentifier":[{"@type":"NRID","@value":"9000020871402"}],"foaf:name":[{"@language":"en","@value":"Walker William"}],"jpcoar:affiliationName":[{"@language":"en","@value":"Fujitsu Laboratories of America, USA"}]},{"@id":"https://cir.nii.ac.jp/crid/1410001205222061057","@type":"Researcher","personIdentifier":[{"@type":"NRID","@value":"9000020871397"}],"foaf:name":[{"@language":"en","@value":"Okawara Hideki"}],"jpcoar:affiliationName":[{"@language":"en","@value":"Fujitsu Laboratories Ltd., Japan"}]},{"@id":"https://cir.nii.ac.jp/crid/1410001205222061056","@type":"Researcher","personIdentifier":[{"@type":"NRID","@value":"9000020871382"}],"foaf:name":[{"@language":"en","@value":"Ando Hisashige"}],"jpcoar:affiliationName":[{"@language":"en","@value":"Fujitsu Limited, Japan"}]}],"publication":{"publicationIdentifier":[{"@type":"EISSN","@value":"13497456"},{"@type":"LISSN","@value":"13497456"}],"prism:publicationName":[{"@language":"en","@value":"IPSJ Digital Courier"},{"@language":"en","@value":"ipsjdc"}],"dc:publisher":[{"@language":"en","@value":"Information Processing Society of Japan"},{"@language":"ja","@value":"一般社団法人 情報処理学会"}],"prism:publicationDate":"2005","prism:volume":"1","prism:startingPage":"204","prism:endingPage":"215"},"reviewed":"false","url":[{"@id":"http://www.jstage.jst.go.jp/article/ipsjdc/1/0/1_0_204/_pdf"}],"availableAt":"2005","foaf:topic":[{"@id":"https://cir.nii.ac.jp/all?q=General%20Economics,%20Econometrics%20and%20Finance","dc:title":"General Economics, Econometrics and Finance"}],"relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1360011145577544704","@type":"Article","relationType":["references"],"jpcoar:relatedTitle":[{"@value":"The Stanford Hydra CMP"}]},{"@id":"https://cir.nii.ac.jp/crid/1360855569362186240","@type":"Article","relationType":["references"],"jpcoar:relatedTitle":[{"@value":"Performance of database workloads on shared-memory systems with out-of-order processors"}]},{"@id":"https://cir.nii.ac.jp/crid/1360855570043457280","@type":"Article","relationType":["references"],"jpcoar:relatedTitle":[{"@value":"Piranha"}]},{"@id":"https://cir.nii.ac.jp/crid/1361699994595061760","@type":"Article","relationType":["references"],"jpcoar:relatedTitle":[{"@value":"Memory system characterization of commercial workloads"}]},{"@id":"https://cir.nii.ac.jp/crid/1363388845642494464","@type":"Article","relationType":["references"],"jpcoar:relatedTitle":[{"@value":"POWER4 system microarchitecture"}]},{"@id":"https://cir.nii.ac.jp/crid/1363670320623766400","@type":"Article","relationType":["references"],"jpcoar:relatedTitle":[{"@value":"Microarchitecture and performance analysis of a SPARC-V9 microprocessor for enterprise server systems"}]},{"@id":"https://cir.nii.ac.jp/crid/1363951794030964224","@type":"Article","relationType":["references"],"jpcoar:relatedTitle":[{"@value":"Exploring microprocessor architectures for gigascale integration"}]},{"@id":"https://cir.nii.ac.jp/crid/1363951794607010176","@type":"Article","relationType":["references"],"jpcoar:relatedTitle":[{"@value":"Architecture of the Atlas chip-multiprocessor: dynamically parallelizing irregular applications"}]},{"@id":"https://cir.nii.ac.jp/crid/1363951795383173760","@type":"Article","relationType":["references"],"jpcoar:relatedTitle":[{"@value":"A 1.3-GHz fifth-generation SPARC64 microprocessor"}]}],"dataSourceIdentifier":[{"@type":"JALC","@value":"oai:japanlinkcenter.org:0024955809"},{"@type":"CROSSREF","@value":"10.2197/ipsjdc.1.204"},{"@type":"CIA","@value":"130000022393"}]}
