1、arm嵌入式系统论文ARM Embedded System PaperARM嵌入式论文ARM introductionIf, say, embedded is 2008 years electronic engineer talking about one of the most word in 2009, most of the talk about a word is ARM. What is ARM? He is a British electronic company name, the full name mean Advanced RISC Machine. The company

2、 was founded in November 1990, is apple computer, Acorn computer group and VLSI Technology of the joint venture. Acorn has launched the worlds first commercial single chip RISC processors, and apple computer was hope will RISC technology in their own system, the ARM microprocessor new standards so a

3、rises at the historic moment.如果,说,“嵌入式”是2008年电子工程师谈论的一个最字2009年,大多数的谈论一个单词是“手臂”。手臂是什么?他是一个英国电子公司的名字,全名是先进的RISC机器。公司成立于1990年11月,是苹果电脑,Acorn计算机集团和VLSI技术的合资企业。Acorn已经推出了世界上第一个商业单片RISC处理器,和苹果电脑是希望将RISC技术在自己的系统中,ARM微处理器新标准应运而生。At the end of 80 s, 90 s semiconductor industry chain just appear division of l

4、abor, TSMC, LianDian semiconductor foundry etc are slowly rise, some of the silicon valley fabless companies also have mushroomed emerging as, so-called fabless design company chip, but the production process is the package to give TSMC foundry production etc. And ARM is for the world first, 19 year

5、s ago created chipless production model, that is, the company is neither production chip, also dont design chips, but the design of effective IP kernel, to authorize a semiconductor companies use, semiconductor company in the ARM technology based on add your own design and introduction of chip produ

6、cts, finally by OEM customers use these chips to construct the system based on ARM technology products. This way, a bit like the communications industry in the qualcomm and the semiconductor industry RAMBUS, they stand in the semiconductor industry chain upstream of the upstream. 19 years ago formed

7、 ARM may face a lot of risk, because no one know the road can not work, but now the facts have proved, ARM away a no man through, but it is the right path. As additional products, he also let Chinas industry members from the window to understand the British electronics company, the success of the AR

8、M of the British chipless led the development of the company.80年代末,90年代半导体产业链分工出现,台积电,LianDian半导体等正在慢慢上升,硅谷的一些专业公司也如雨后春笋般涌现的新兴,所谓专业设计公司芯片,但生产过程是包给台积电铸造生产等和手臂是世界第一,19年前创建无屑的生产模式,也就是说,公司既不生产芯片,也不设计芯片,但设计有效的IP内核,授权一个半导体公司使用,半导体公司在ARM技术的基础上添加自己的设计和芯片产品的介绍,最后通过OEM客户使用这些芯片构建系统基于ARM技术的产品。这样,有点像高通的通信行业和半导体行

9、业RAMBUS,他们站在半导体产业链上游的上游。19年前形成的手臂可能面临很多的风险,因为没有人知道这条路不能工作,但是现在,事实已经证明,手臂没有人通过,但这是正确的道路。作为额外的产品,他还让中国从窗口行业成员理解英国电子公司的成功的英国无屑的公司的发展。Because ARM of the product is IP Core, without any physical sense of hardware or software entities, therefore can only registered in China to become consultation company,

10、 despite of its business consulting is just a few. ARM the core business is selling chips core technology IP, at present the whole world has 103 giant IT company in the home ARM technology, 20 largest semiconductor manufacturers in 19 is the ARM users, including Texas instruments, stmicroelectronics

11、, Philips, Intel, etc. The only 20 giants didnt buy ARM authorized is the old Intel rival AMD, Intel because the StrongARM processor is portable, and AMD is the acquisition of the Alchemy company fight, used the MIPS structure.因为产品的手臂是IP核,没有任何硬件或软件实体的物理意义,因此只能在中国注册成为“咨询”公司,尽管其业务咨询只是少数。ARM核心业务是销售芯片核心

12、技术知识产权,目前全世界有103家中大型IT公司ARM技术,20 19手臂用户最大的半导体制造商,包括德州仪器、意法半导体、飞利浦、英特尔等。只有20个巨人没有买手臂授权是古老的英特尔竞争对手AMD,英特尔因为StrongARM处理器是便携式,和AMD是炼金术的收购公司,使用了MIPS结构。ARM product introductionARM offer a series of core, system expansion, microprocessor and system chip solutions. Because all products are used a general so

13、ftware system, so the same software can be in all products operation (in theory so). Typical products as follows.臂产品介绍部门提供一系列核心,系统扩张,微处理器和系统芯片的解决方案。因为所有的产品都是使用一种通用的软件系统,所以相同的软件可以在所有产品操作(在理论上)。典型的产品如下。CPU core (CPU核心)ARM7TDMI (Thumb) : this is the most authorized users a product will ARM7 instruction

14、 set with Thumb extension together, in order to reduce memory capacity and system cost. At the same time, it also use embedded ICE commissioning technical to simplify system design, and a digital signal processor (DSP) enhance extended to improve performance. The product of the typical application i

15、s digital cellular phones and hard disk drives.ARM7TDMI(拇指):这是最授权用户的产品将与拇指ARM7指令集扩展在一起,以减少内存容量和系统成本。与此同时,它也使用嵌入冰调试技术来简化系统的设计,和数字信号处理器(DSP)增强扩展来提高性能。产品的典型应用是数字蜂窝电话和硬盘驱动器。ARM710 series, including ARM710, ARM710T, ARM720T and ARM740T: low price, low energy consumption, encapsulation type routine system
