  lang=EN-US>ADI DSP</span>，有什么特点，有些什么型号？<span lang=EN-US> ADI</span>的全称是<span
  lang=EN-US>Analog Device Inc</span>（美国模拟器件有限公司）。<span lang=EN-US>ADI DSP</span>是美国模拟器件公司推出的<span
  lang=EN-US>dsp</span>的统称，相对与<span lang=EN-US>ti</span>公司的<span lang=EN-US>dsp</span>系列，具有内部<span
  lang=EN-US>mem</span>较大，多片协同工作能力强等优点，具体可查阅<span lang=EN-US>ADI</span>公司<span
  lang=EN-US>http://www.analog.com </span>主要有以下几个系列的<span lang=EN-US>DSP:
  a)21xx</span>系列：<span lang=EN-US>16</span>位定点<span lang=EN-US>dsp</span>，主要以<span
  lang=EN-US>218x</span>和<span lang=EN-US>219x</span>系列为代表，性能优异，内部<span
  lang=EN-US>RAM</span>大，外围接口多，适合作为控制类芯片使用，其中<span lang=EN-US>219x</span>系列性能更高。<span
  lang=EN-US> b)SHARC</span>系列：<span lang=EN-US>32</span>位浮点<span lang=EN-US>dsp</span>，包括前期的<span
  lang=EN-US>2106x</span>系列，和目前的主力<span lang=EN-US>21160,21161</span>系列，提供与大内存容量结合的简单浮点算法，具有高水平的浮点性能。<span
  lang=EN-US> c)TigerSHARC</span>系列：从<span lang=EN-US>SHARC</span>系列发展而来，比<span
  lang=EN-US>SHARC</span>具有更高的浮点运算功能，目前有<span lang=EN-US>TS101,TS201</span>两个系列。<span
  lang=EN-US> d)blackfin</span>系列：<span lang=EN-US>ADI</span>最新推出的一款<span
  lang=EN-US>dsp</span>，是高性能<span lang=EN-US>16</span>位<span lang=EN-US>DSP</span>信号处理能力与通用微控制器使用方便的性能结合。主要型号有<span
  lang=EN-US>BF531,BF532,BF533,BF535</span>等型号。 除此外还有<span lang=EN-US>21065</span>是一种混合<span
  lang=EN-US>DSP</span>，可以作为<span lang=EN-US>32bit</span>的定点运算，也可以设定作为<span
  lang=EN-US>32bit</span>或是<span lang=EN-US>40bit</span>的浮点运算。 <span

  dsp</span>都有相应的软件，均可在<span lang=EN-US>ADI</span>网站<span lang=EN-US>www.analog.com</span>上下载得到。在网站上可申请<span
  lang=EN-US>testdriver</span>（测试版）的<span lang=EN-US>serial number</span>（该系列号以<span
  lang=EN-US>TST</span>打头），可以使用<span lang=EN-US>90</span>天试用期。<span lang=EN-US>90</span>天后需要重新安装系统。关于<span
  lang=EN-US>serial number </span>有几种：<span lang=EN-US> tst</span>打头的： 是测试版的系列号，一般可以使用<span
  lang=EN-US>30</span>天、<span lang=EN-US>60</span>天、<span lang=EN-US>90</span>天、<span
  lang=EN-US>255</span>天等几种；<span lang=EN-US> adi</span>打头的：是正版系列号，可以用这个号码最终到<span
  lang=EN-US>ADI</span>网站进行注册，一般一个号码仅可以在一台电脑上运行的。<span lang=EN-US> kit</span>打头的：是适用于用于评估芯片的评估板的系列号，在应用时对于芯片的内存等方面有一些限制。
  注意：当你拿到<span lang=EN-US>testdriver</span>的序列号时，先将系统时间改到<span lang=EN-US>n</span>年以后，注册，最后再把时间改回来，这样就可以使用较长的一段时间了。<span
  lang=EN-US>ADI</span>公司得<span lang=EN-US>Visual DSP++</span>软件在设计上进行了加密，据相关人士介绍，总共在硬盘上进行<span
  lang=EN-US>7</span>处加密，一般情况下，很难被破解。 <span lang=EN-US><o:p></o:p></span></span></p>

  lang=EN-US>dsp</span>中，在线调试，断点，观察<span lang=EN-US>mem</span>，<span
  lang=EN-US>REG</span>等，是<span lang=EN-US>DSP</span>开发中不可缺少的东西。目前<span
  lang=EN-US>ADI</span>的仿真器在国内没有第三方开发，只能购买原装的，优点是质量可以得到保证，但一旦仿真器损坏，返修会耗费较长的一段时间。<span
  lang=EN-US>ADI</span>得开发工具有集中型号的：<span lang=EN-US>PCI</span>板卡方式的、<span
  lang=EN-US>USB</span>方式的。评估板：每种<span lang=EN-US>DSP</span>系列都有对应的评估板，评估板的原理图可以称为该款<span
  lang=EN-US>dsp</span>硬件设计的典范，可以根据该评估 板的设计原理图进行设计，很多地方可以完全照搬，真的很方便。拥有评估板可以使新手更快地掌握该型号的<span
