eMMC (Embedded Multi Media Card)是MMC协会订立、主要针对手机或平板电脑等产品的内嵌式存储器标准规格。eMMC在封装中集成了一个控制器,提供标准接口并管理闪存,使得手机厂商就能专注于产品开发的其它部分,并缩短向市场推出产品的时间。MMC的应用是对存储容量有较高要求的消费电子产品。2011年已大量生产的一些热门产品,如Palm Pre、Amazon Kindle II和Flip MinoHD,都采用了eMMC。为了确认这些产品究竟使用了何种存储器,iSuppli利用拆机分析业务对它们进行了拆解,发现eMMC身在其中。附件为介绍EMMC5.1标准的数据手册.

摘要:本系统以ICL8038集成块为核心器件,制作一种函数信号发生器,制作成本较低。适合学生学习电子技术测量使用。ICL8038是一种具有多种波形输出的精密振荡集成电路,只需要个别的外部元件就能产生从0.001Hz~30KlHz的低失真正弦波、三角波、矩形波等脉冲信号。输出波形的频率和占空比还可以由电流或电阻控制。另外由于该芯片具有调制信号输入端,所以可以用来对低频信号进行频率调制。关键词:函数信号发生器频率调制Abstract:The system ICL8038 integrated block as the core device,producing a kind of function signal generator,producing low cost.Suitable for students to learn the use of electronic technology measurement.ICL8038 is a kind of multi-precision oscillator waveform output integrated circuits,a separate external components only need to be able to generate from the 0.001Hz ~30KHz low-distortion sine wave,triangle wave,square wave pulse signal,etc..Output waveform of the frequency and duty cycle can also be controlled by a currentor resistance.In addition,as the chip has a modulated signal input terminal,it can be used to low-frequency signal is frequency modulation.

IEEE1149.1的产生1985年由IBM、AT&T、Texas Instruments、Philips Electronics NV、Siemens、Alcatel和Ericsson等公司成立的JETAG(Joint European Test Action Group)提出了边界扫描技术。1986年由于其它地区的一些公司的加入,JETAG改名为JTAG。1988年JTAG提出了标准的边界扫描体系结构,名称叫Boundary-Scan Architecture Standard Proposal,Version2.0,1990年IEEE正式承认了JTAG标准,经过补充和修订以后命名命名为IEEE1149.1-90。同年又提出了BSDL(Boundary Scan Description Lauguage,边界扫描描述语言)。后来成为IEEE1149.1-93标准的一部分。

VME has been the de-facto bus standard for Commercial off the Shelf(COTS ) Circuit Card Assemblies since the 1980's. VME boards have proven to be remarkably capable of evolving to support newer technologies with innovations such as VME Subsystem Bus, PCI Mezzanine Cards(PMC's) and VME320.However, advances in technologies, appearing particularly in interconnects, have demonstratedthe need for an advance in system development. This advance needs to accommodate high speed interconnect, particularly serial interconnects, and higher power delivery in concert with better heat removal.
