2014的今年將會是64-bit應用處理器大放異彩的元年,Microprocessor Report如是說。

縱使64位元Android可能要到年底才會現身,Qualcomm一干業界主力受Apple A7處理器刺激,正急著推出足以抗衡的64-bit戰將。

Next year(2014), the story in mobile processors will be 64 bits as more Cortex-A50-powered devices come to market in smartphones and tablets.
- Mike Demler of Microprocessor Report

鑒於64位元Android仍未上市,Demler指出,此時正是剛併購MIPS的GPU大佬Imagination挑戰ARM的最佳切入點。

Imagination will need to accelerate the MIPS64 development schedule to catch up, but the combination of Warrior CPUs and PowerVR GPUs may become a more competitive platform as heterogeneous computing becomes more prevalent in application processors.

Demler同時呼籲ARM加速128位元的ARMv9開發。

ARM introduced the 64-bit ISA in 2011, so by 2015, it may be time to roll out the next-generation ARMv9.

記憶體廠商推波助瀾,有望加速64-bit行動處理器在smartphone、tablet擴張,甚至滲透未來的筆電、桌機市場,實現ARM入侵主流運算領域的野心。

ARM's upcoming Cortex-A53 and A57 chips will allow tabletlike devices to go from information consuming devices to information creation devices.
- Noel Hurley, vice president of marketing and strategy at ARM


同時開發LPDDR4 Mobile DRAM的SK Hynix與Samsung,確定由Samsung出線。後者目前已出貨4Gb、6Gb LPDDR3(4顆die堆疊成3GB)產品,並完成8Gb顆粒(單die為1GB容量)的20nm製程開發,預定今年2014量產。普遍認為,LPDDR4到2016年將取代現行的LPDDR3成為行動裝置主流。



















由Samsung向JEDEC提案的Low Voltage Swing Terminated Logic(LVSTL低電壓擺幅中斷邏輯)I/O界面,具3.2Gbps傳輸速率,額定電壓僅為1.1V。
