AMD Excavator Family 15h is a microarchitecture under development by AMD to succeed Steamroller Family 15h. On October 12, 2011, AMD revealed Excavator to be the code name for the fourth-generation Bulldozer-derived core. The Excavator-based APU for mainstream applications will be called ''Carrizo'' and is scheduled for a 2015 release. The ''Carrizo'' APU is designed to be HSA 1.0 compliant. An Excavator-based APU and CPU variant named ''Toronto'' for server and enterprise markets will also be available. Excavator has been confirmed to be AMD's final revision of the 'Bulldozer' family, with two new microarchitectures replacing Excavator a year later. 〔http://www.bit-tech.net/news/hardware/2014/09/11/amd-zen/1〕〔http://www.xbitlabs.com/news/cpu/display/20140510165441_AMD_to_Introduce_New_High_Performance_Micro_Architecture_in_2015_Report.html〕 The next generation sister architectures will be the x86-64 Zen and AArch64 K12 architectures. ==Architecture== Excavator is expected to support new instructions such as AVX2, BMI2 and RdRand. Excavator is also expected to come with DDR3 and DDR4 memory controllers, currently not known if on the same die or mutually exclusive.〔 Excavator is designed using High Density (aka "Thin") Libraries normally used for GPUs to reduce electric energy consumption and die size, delivering a 30 percent increase in efficient energy use.〔http://www.tomshardware.com/news/Steamroller-High_Density_Libraries-hot-chips-cpu-gpu,17218.html〕 Excavator can process up to 15% more instructions per clock compared to AMD's previous core Steamroller.〔http://wccftech.com/amd-carrizo-apu-architecture-hot-chips/〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Excavator (microarchitecture)」の詳細全文を読む スポンサード リンク
