《计算机体系结构:量化研究方法(英文版•第3版)》不要内容：　The　third　edition　of　Computer　Architecture:　A　Quantitative　Approach　should　have　been　easy　to　write.　After　all,　our　quantitative　approach　hasn't　changed,　and　we　sought　to　continue　our　focus　on　the　basic　principles　of　computer　design　through　two　editions.　The　examples　had　to　be　updated,　of　course,　just　as　we　did　for　the　second　edition.　The　dramatic　and　ongoing　advances　in　the　field　as　well　as　the　creation　of　new　markets　for　computers　and　new　approaches　for　those　markets,　however,　led　us　to　rewrite　almost　the　entire　book.　The　pace　of　innovation　in　computer　architecture　continued　unabated　in　the　six　years　since　the　second　edition.　As　when　we　wrote　the　second　edition,　we　found　that　numerous　new　concepts　needed　to　be　introduced,　and　other　material　designated　as　more　basic.　Although　this　is　officially　the　third　edition　of　Computer　Architecture:　A　Quantitative　Approach,　it　is　really　our　fifth　book　in　a　series　that　began　with　the　first　edition,　continued　with　Computer　Organization　and　Design:The　Hardware/Software　Interface　(COD:HIS),　and　then　the　second　edition　of　both　books.　Over　time　ideas　that　were　once　found　here　have　moved　to　COD:HIS　or　to　background　tutorials　in　the　appendices.　This　migration,　combined　with　our　goal　to　present　concepts　in　the　context　of　the　most　recent　computers,　meant　there　was　remarkably　little　from　the　second　edition　that　could　be　preserved　intact,　and　practically　nothing　is　left　from　the　first　edition.
