高端军用嵌入式应用开始向intel迁移

Trends in microprocessors: high-end military embedded applications are beginning a shift to Intel
高端军用嵌入式应用开始向intel迁移 By John Keller

When it comes to military embedded computing, basically only two microprocessor manufacturers slug it out for the lion's share of the defense and aerospace embedded computer market-Freescale Semiconductor Inc. in Austin, Texas, and Intel Corp. of Santa Clara, Calif.
目前国防和航空嵌入式计算市场有两个选择： Freescale 在奥斯丁，和intel 在santa calra

While Freescale has been this market's 500-pound gorilla for some time, Intel's latest introduction of its Core i7 microprocessor in January is tipping the defense embedded systems community on its head in a transformation the likes of which seasoned observers have not seen in years.

Freescale像一个500磅的黑猩猩一样占有这个市场一段时间了， inte在一月推出了的Core I7微处理器将会颠覆这个市场

The newest Core i7 "is unlike anything we've got," says Frank Willis, director of military and aerospace product development at GE Intelligent Platforms in Albuquerque, N.M. "It's going to set the standard for performance as we move ahead. This gives Intel unbelievable capability and entry into the market."

新的Core I7" 和从前完全不一样" ，佛兰克.威尔士说 ，他是位于新墨西哥州的阿尔布开克的GE 智能平台的 军用宇航产品开发部的总监
"它设定了新的性能标准就像我们努力地那样，这给了intel难以置信的技术水准，进入这市场"
Sure, there are plenty of other important microprocessor makers-Advanced Micro Devices Inc. (AMD) of Sunnyvale, Calif.; ARM Inc. of Los Gatos, Calif.; Cavium Networks of Mountain View, Calif.; and MIPS Technologies Inc. of Mountain View, Calif. among them-but for military embedded applications, Freescale primarily, and to a lesserextent Intel, have been the processors of choice.
当然，现存有充分的重要的处理器制造商--- AMD, Cavium networks， MIPS。但是就军用嵌入式的引用来看 ，Freescale在过去的岁月里，稍微胜出intel而成为首选。

Of the leading two companies, Freescale by far has been the more dominant over the past several years based on its marquee embedded microprocessor, the Power PC (and later Power Architecture) with the AltiVec floating point and integer SIMD instruction set-for applications like radar, sonar, and signals intelligence that need floating-point processing.

Freescale占有市场的利器PowerPC （ 后来的power 架构） ，最重要的特性- Altivec 浮架构和单指令流多数据流指令集，非常适合雷达，声纳和其他信号处理系统，这些系统都需要浮点处理能力

The performance, flexibility, and power consumption of the Power Architecture has kept Freescale on the top of the mountain for a long time, and not just because of floating-point processing. The Power Architecture also fits well with the VME backplane databus that has dominated military embedded computing for much of the chip's reign.
不仅因为浮点性能，性能，灵活性，power架构的能耗 都使得freescale上期处于市场的巅峰， power架构和VME背板总线长期统治军用嵌入式计算环境（注： freescale 芯片直接能引出VME总线，不需要桥接芯片）。
Aerospace and defense systems designers, despite getting what they needed from Freescale, always wanted an alternative source of microprocessors, just in case Freescale changed their microprocessor architectures.
宇航和国防系统设计者，尽管清楚他们需要Freescale，但是他们换需要另外的处理器来源，防止Freescale改变处理器架构
For a while, defense and aerospace embedded computer makers hung their hopes on a company in Santa Clara, Calif., called P.A. Semi as an alternative to Freescale. P.A. Semi experts were developing a powerful and power-efficient Power Architecture processor called PWRficient, which met their needs. Hopes were dashed, however, when Apple Computer acquired P.A. Semi, and took P.A. Semi products off the open market.
他们曾经寄希望于另外一个公司，P.A 作为freescale的替代品， P.A的专家开发一种性能强劲，功耗优良的处理器叫做PWRficien，能满足军方的需求。但是希望落空了，apple收购了P.A，P.A转向了开放市场

Then the fears of high-end military systems designers were realized. Freescale, in a bid to dominate the cell phone and handheld appliance market, decided to abandon AltiVec and floating-point capability in its latest generation of microprocessors, which dropped a monkeywrench into long-term planning among the military embedded computing companies. "The Freescale PowerPC roadmap is dead-ended now at AltiVec," says Doug Patterson, vice president of marketing at Aitech Defense Systems Inc. in Chatsworth, Calif.
然后让他们担心的事情发生了，Freescale 决定在下一代的处理器仲放弃AltiVec和浮点性能，这有些戏弄那些以freescale作为长期策略和计划的嵌入式计算业者。
"Freescale PowerPC roadmap结束了Altivec" ，doug patterson说，他是Aitech国防系统的主管市场的副总裁

Then Intel quietly made it known that help was on the way; the company was working on a high-performance, low-power chip with floating-point capability. Embedded computer designers made plans to take advantage.
intel 让许多人相信他们能够帮助解决这问题，他在生产高性能，低功耗和优良浮点运算的处理器，嵌入式业者计划采用这些优势产皮

Intel formally altered the balance in January 2010 with its announcement of the latest-generation Core i7 microprocessor with floating-point capability. Several embedded computing products aimed at aerospace and defense applications were introduced within hours of the Intel Core i7 introduction, with additional products coming out nearly every day afterwards.

intel宣布了最新的Core i7，几个嵌入式业着随后在咋这个会上宣布很快将会推出相关产品

"The biggest feature of the Core i7 is the floating-point performance," says Ben Klam, vice president of engineering at Extreme Engineering Solutions (X-ES) in Middleton, Wis. "Now they are getting into lower-power embedded applications with good performance, which will help any military applications that benefit from floating point, like radar and signal processing."

"I7 最大的性能优势是浮点处理能力" ben klam说，他是X-ES的工程副总裁" 现在我们将会有良好性能，同时较低功耗的应用产品，这将使得雷达和其他需要浮点处理能力的军用应用系统从中获益"


None of this is to say that Freescale will not be part of aerospace and defense applications in the future; far from it.
这并非说，Freesc从此不再在宇航和国防应用中出现

Steve Edwards, chief technology officer at Curtiss-Wright Controls Embedded Computing in Leesburg, Va., says the military and aerospace embedded computing market essentially has three components-high-end digital signal processing (DSP) applications; general-purpose processing; and low-power mobile applications.
Steve Edwards， Curtiss-Wright 的技术总监，说军用和余杭市场有3种必须的器件
-高端DSP，通用处理器，低功耗mobile应用


Edwards says Intel may well come to dominate military DSP applications in the near term because of the Core i7's floating-point capability, yet he sees continued vigorouscompetition between Intel and Freescale in general-purpose processing and low-power embedded computing applications.
Edwards说intel也许会很愿意进入DSP 应用市场，因为他的CoreI7拥有良好的浮点性能，
他看到intel和Freescale 在GPCPU和低功耗mobile computing中持续激烈的竞争

General-purpose processing in aerospace and defense applications "is split between the Power Architecture and Intel," Edwards says. "We see a huge market for the Freescale Power Architecture for highly integrated applications that need multiple cores, Ethernet controllers, and very small-footprint solutions."
GP 市场分成了 Power架构和intel架构，Edwards说，" 我看到Freescale一个巨大的市场 那就是高集成度应用-他们需要多核，以太网控制器，小的体积和PCB面积等等"

General-purpose processing applications moving into the Intel camp, meanwhile, favor Intel's tie-in with the Windows desktop operating system, other commercial software with familiar man-machine interfaces, and embedded Linux, he says.
GPP 将迁移到intel平台，同时和intel关系紧密的windows 桌面平台，其他的商用软件，比如我们熟悉的人际界面和linux等等都将相继而来


Low-power applications such as man-portable systems and small unmanned aerialvehicle (UAV) payloads also should remain a tossup between Intel and Freescale in the future, Edwards says, as both companies offer equivalent products.
低功耗市场，比如单兵便携系统，无人机 将维持现在的竞争态势，intel和free都提供相应的产品

In high-end DSP applications, however, aerospace and defense systems designers are coming out with distinct preferences for the new Intel microprocessor. "The bar for this capability has been set," says GE's Willis. "You will have to see Freescale step up to this level to stay competitive."

在高端DSP应用，宇航和军用系统设计者已经清楚的认识到intel的性能 " 标杆已经设立" wills说" 我们将不得不看到Freescale需要努力达到这个水准，才能维持竞争力"
