AMD makes Fusion CPU, GPU agnostic
AMD要让Fusion实现CPU、GPU的彻底融合

Microprocessor vendor Advanced Micro Devices Inc. has declared that Fusion, its flagship processor project whereby it has combined x86 and graphics processors, will be CPU and GPU agnostic. The announcement was made as part of a keynote at the Fusion Developers Summit, being held in Bellevue, Washington, by Phil Rogers, AMD Corporate Fellow.
微处理器厂商AMD宣布Fusion处理器将彻底融合CPU与GPU。Fusion是AMD的旗舰处理器,整合了x86处理器和图形处理器。AMD公司院士Phil Rogers在华盛顿贝尔维尤举行的Fusion开发者峰会的一个主题演讲中宣布了此消息。

The early examples of Fusion have been based on x86 processor and GPU cores developed internally by AMD. However, AMD is clearly heading for a higher level of abstraction and believes it can do better by letting multiple hardware and software companies join with it as it tries to enable heterogeneous computing. It is effectively turning the Fusion marketing brand into the open Fusion System Architecture with a specification that enables chipmakers to combine multiple CPUs and GPUs and preserve an efficient programming model.
Fusion的早期样片基于AMD内部开发的x86处理器和GPU。但AMD显然向着更抽象的层面前进,相信自己可以让多加硬件和软件厂商加入进来,开启异构计算(heterogeneous computing)。AMD将Fusion品牌变成开放的Fusion系统架构,通过一套规范让芯片制造商整合多种CPU和GPU,并提供一套高效的编程模型。

The development is likely to allow ARM cores to be used as part of the Fusion architecture although Rogers did not mention ARM explicitly as he laid out the open-platform plan for Fusion.
这项进展可能意味着ARM内核也能称为Fusion架构的一部分,不过Rogers在介绍开放平台计划时没有明确提到ARM。

The main thrust of Roger's keynote was that AMD wants to create an architecture whereby different combinations of CPU and GPU processor cores operate as a unified processing engine that delivers both higher performance and lower power consumption compared with today's variants.
Roger演讲的重点是AMD希望创造一套让不同的CPU、GPU组合像统一的处理引擎一样工作的架构,在提供更高性能的同时消耗更少的电力。

Having discussed the historical trends from single- to multicore and on to heterogeneous multicore computing it was about half-way through the talk that Rogers described the Fusion System Architecture as an "open platform" and added that this meant the virtual ISA specification, known as FSAIL, the memory model the despatch mechanism would be published.
Rogers也谈到了单核到多核再到异构多核计算的历史趋势,他将Fusion系统架构描绘成一个“开放平台”,并补充说虚拟ISA规范(FSAIL)、内存模型和分配机制也会随之发布。

Rogers said: "The Fusion system architecture is ISA agnostic for both CPUs and GPUs. This is very important because we're inviting partners to join us in all areas; other hardware companies to implement FSA and join in the platform; operating systems companies to fully embrace all of the features and deliver its full performance and quality of service; tools and middleware companies to provide the tool infrastructure to develop, optimize and debug the programs that will run on this platform."
Rogers说:“Fusion系统架构的ISA是CPU、GPU中立的。这很重要,因为我们正在所有领域邀请合作伙伴加入:其它硬件厂商实现FSA、加入平台;操作系统公司全面支持所有功能、提供完整的性能和服务质量;工具和中间件公司提供工具基础来开发、优化用于这个平台的程序。”

He added that an FSA review committee would be formed to guide the evolution of the architecture and to allow all participants a voice in its direction.
Rogers还补充说未来将会成立一个FSA评估委员会指导架构的进化,让所有参与者都能在决定发展方向是有发言权。

unified memory and programming models
统一的内存和编程模型

Rogers said that current heterogeneous multicore architectures are currently constrained by the programming model and communications overheads. "The good news is the Fusion System Architecture blows away both of these constraints," he said. "Where we're headed is the architected era. We make the GPU into a peer processor rather than a device," he said.
Rogers说目前的异构多核架构被编程模式和通信开销所束缚,“好消息是Fusion系统架构接触了这些束缚。我们正在向架构时代前进。我们将GPU变成一个同等的处理器而不是一个设备”。

Rogers outlined a roadmap that includes support for C++ features, unification of the address space, support for nested data parallelism, user-mode scheduling for lower latency task dispatch between CPUs and GPUs, and the addition of pre-emption and context switching.
Rogers描绘了一个路线图,其中有对C++特性的支持、统一地址空间、支持嵌套的数据并行模型、在CPU和GPU之间实现低延时任务分配的用户态调度机制以及抢占和上下文切换。

Automated lower balancing between CPU and GPU is part of that progress, according to Rogers. In addition, specific FSA enhancements will be supported by newer programming languages and interfaces such as OpenCL and DirectCompute. One of the next steps will be the addition of bi-directional power management to CPU, GPU combinations. But the key is the creation of a unified memory address space and fully coherent memory shared by the CPU and GPU so they operate seamlessly together, Rogers said.
这个过程中也会实现自动低平衡。此外,具体的FSA增强会得到OpenCL、DirectCompute等新编程预言和接口的支持。接下来还要为CPU、GPU的组合提供增加双向功率管理。不过Rogers强调,最关键的是创建统一的内存地址空间,让CPU和GPU完全共享内存以实现无缝的运作。

What was not made clear in what was essentially a technical presentation is how AMD, as one of a number of implementors and contributors to the Fusion System Architecture will make its money from the development of Fusion.
在这次技术性演讲中没有说明的是AMD作为Fusion系统架构实现者与贡献者中的一员,如何从Fusion的发展中获利。

话题PK
三星手机在中国是否会雪崩式倒下?

MOTO、NOKIA、索尼等手机巨头都是雪崩式倒下,三星手机最近也遭遇到市场近几年来首次的下滑。这是三星手机暂时性的困难,还是三星手机正在重走其它手机国际巨头的老路,积重难返,从此被国产手机所取代?欢迎大家表达自己的看法,谢谢。

正方:?三星手机在中国肯定会倒下。

反方:?三星手机还有能力东山再起。
