There are currently no mainstream general-purpose processors built to operate on 512-bit integers or addresses, though a number of processors do operate on 512-bit data. , the Intel Xeon Phi has a vector processing unit with 512-bit vector registers, each one holding sixteen 32-bit elements or eight 64-bit elements, and a single instruction can operate on all these values in parallel. However, the Xeon Phi's vector processing unit does not operate on individual numbers that are 512 bits in length. ==Uses== * Some GPUs such as the Nvidia GTX280, GTX285, Quadro FX 5800 and several Tesla products move data across a 512-bit memory bus. Then AMD Radeon R9 290 and 295X2 followed. * Many hash functions, such as SHA-512, have a 512-bit output. * A 512-bit CPU would be capable of addressing 384 yottabytes. * AVX-512 are 512-bit extensions to the 256-bit Advanced Vector Extensions SIMD instructions for x86 instruction set architecture proposed by Intel in July 2013, and scheduled to be supported in 2015 with Intel's Knights Landing processor. 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「512-bit」の詳細全文を読む スポンサード リンク
