arm-big-little-layout  

近年來 Samsung 在行動晶片領域取得了非常不錯的成績(如 Exynos 4 Quad、Exynos 5 Dual 處理器),今天我們又收到消息,稱在明年 2 月 19 日舉行的國際固態電路大會(International Solid-State Circuits Conference)上他們將推出使用 ARM「大小核架構」(big.LITTLE)的八核心處理器。它將由一顆四核心的 1.8GHz Cortex-A15 處理器和另一顆四核心的 1.2GHz Cortex-A7 處理器組合而成,前者負責繁重的運算,後者則用來處理較為輕鬆的任務。

Samsung's processor design team has been on a roll with fast chips this year with the Exynos 4 Quad and Exynos 5 Dual. Based on its agenda for the International Solid-State Circuits Conference, that momentum isn't about to stop. A company presentation at the event on February 19th will delve into a new heterogeneous, 8-core processor that relies on ARM's concept of big.LITTLE computing: one half is a quad-core, 1.8GHz ARM Cortex-A15 that will do all the heavy lifting, while the other is a quad 1.2GHz Cortex-A7 that takes over in quieter moments. We don't know much more about the chip beyond the expected 28-nanometer manufacturing process, but it's easy to see a mobile chip that's fast without having to consume much energy in its downtime. Most of the mystery surrounds where Samsung will launch the processor first, rather than what it can do: the big.LITTLE chip would be most valuable in a smartphone, but a potentially large size could relegate it to tablets early on.
