intel 缩线程 IPC 提升3-4倍

Intel’s Skylake Processors Allegedly Rocking ‘Inverse Hyper Threading’ – VISC Like Architecture with Massive Single Threaded Performance

Intel’s Skylake series of processors have already been out in the open for quite some time but the actual details of the micro-architecture have been withheld by Intel. The next likely event where Intel may decide to reveal the minute details about its Skylake uarch is at IDF in a few days. A report by Heise.de however, sheds some early light on what the actual rabbit in the figurative hat might be. Something we have suspected for quite some time now, something that is being dubbed as inverse hyper threading by the rumor mill.
英特尔Skylake系列处理器已经出来有段时间了，但是其实际细节一直被英特尔收着。英特尔决定透露该处理器细节的可能场合是几天后的英特尔开发者论坛（IDF).Heise.de的报道可能让（我们）明朗英特尔到底卖的什么药。这就是我们已经推测一段时间的，也是一直传言的“逆向超线程”

Inverse Hyper Threading then, is the ability of multiple (physical) cores to run a single thread or a “big” logical core. This idea is something that has multiple prototype variations and implementations – most notably VISC and MorphCore. It goes without saying that the actual implementation might not be called inverse hyper threading, MorphCore or even VISC, but the general idea behind the implementation is pretty standard. We have already talked in depth about MorphCore before and here is a short summary of the impacts of VISC based architecture.
逆向超线程就是能够让多个物理核心或一个“大”逻辑核心运行单线程。这个想法有多个原型与实现方式，最显著的是VISC 架构或MorphCore。当然，实际实现时也许不叫逆向超线程、MorphCore或VISC 架构。但是他们的理念实际是一样的（是一个标准）。我们以前已深谈过
MorphCore（变体核心）（见我以前在本吧翻译的帖子）。这里对基于VISC架构作用做个总结。

VISC: One of the possible candidates of Intel’s new virtual architecture dubbed “Inverse Hyper Threading”
VISC架构可能是英特尔新的虚拟架构“逆向超线程”的一个候选技术。
The VISC architecture achieves 3-4 times more instructions per cycle (IPC), resulting in 2-4 times higher performance per watt on single- and multi-threaded applications. Moreover, VISC uses a light-weight “virtual software layer” that makes VISC architecture applicable to existing as well as new software ecosystems.” This obviously means that there is going to be an absolutely, absolutely massive boost in performance of single threaded applications in which a Skylake processor is used.
VISC架构可以让IPC提升3到4倍，单线程与多线程应用的每瓦特性能提升2到4倍。而且，VISC架构采用了轻量级的“虚拟软件层”，这样就使得VISC架构能够运行现有以及新的软件生态系统。这明显意味着Skylake处理器的单线程性能绝对会有巨大的提升。
We already had the ability for big cores to be broken down into small (logical) cores – so it was only a matter of time before we got the ability to combing big cores into an even bigger (logical) core. At any rate, we will learn more about just what exactly is going on underneath the hood at IDF, very soon.
我们能够将大核心变成小的逻辑核心（超线程），所以，将大核心合成一个更大的逻辑核心（逆向超线程）只是时间的问题。不管怎样，我们很快就会在IDF上知道更多确切的幕后内容。Intel’s Skylake Processors Allegedly Rocking ‘Inverse Hyper Threading’ – VISC Like Architecture with Massive Single Threaded Performance
