Unlike previous PowerPC designs, the POWER7 FPU merges the scalar and vector FPUs into a single unit executing three floating-point instruction sets: the single and double precision scalar set, the single precision VMX vector set, and the new single and double precision VSX vector and scalar set. Due to a compact buffer-free floor plan and several optimizations in the data and control flow, the streamlined POWER7 FPU achieves a factor of 2 area reduction over the POWER6 design, beyond the normal technology shrink. This results in a very power and area efficient FPU design, supporting a chip frequency of 4.14GHz. A single 64-bit FPU instance measures only 0.26mm2 in 45nm CMOS SOI.","PeriodicalId":272151,"journal":{"name":"2011 IEEE 20th Symposium on Computer Arithmetic","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133246751","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}
