CROSSCORE开发工具--快速轻松地开发数字信号处理软件的方法ADI

简介：

问：请问贵公司的数字信号处理芯片和ti公司的有什么显著的区别和优势呢？
答： ADI的DSP与TI的DSP相比,浮点DSP的性能比TI的优越;定点DSP中,Blackfin比TI的C55系列高速和低功耗.TigerSHARC作为基站的应用,也有很大的优势.

问：开发工具是否提供一些应用程序库函数，如：语音的压缩解压G。723等，TCP/IP  协议栈，H。323 协议栈 等库函数？
答： No. It is provided by ADI, and third party.

问：告诉我们一些中国的第3方！
答： there are some in different area, so which field are you looking for? please contact with our support center for detail. 800-810-1742

问：If there is something wrong with the Emulator I used, that it could not work anymore, what should I do ,may  get rid of the problem?
答： The best thing to do is to contact dsp tools technical support at dsptools.support@analog.com and detail the type of emulator you are using, and the problem you are expierencing.

问：两片ADSP21161,通过LINK口相连，其中一片(DSP1)由FLASH boot,  另一片(DSP2)由DSP1通过LINK口boot,这种方法可以吗？ 系统上电后boot 的具体过程是怎样的？ 是把所有的程序代码都load到DSP1中，然后DSP1再把DSP2的  代码通过 LINK口boot写到DSP2中吗？
谢谢！！！

答： Yes it is possible. The first DSP will be booted from the PROM and then the first DSP would boot the second DSP through the link port. You will have to configure the Boot configuration pins of the DSPs. Please note that you have appropriately select the bo

问：SHARC和TigerSHARC的主要区别是什么?包括性能和开发工具.
答： The main difference is cost / performance ratio. SHARC offers low cost consumer applications, but TigerSHARC is for high performance high end applications. SHARC offers upto 400 MMACS today, while TigerSHARC offers upto 1200 MMACS today. TigerSHARC is used

问：哪里可以得到CROSSCORE的DEMO版
答： You could buy / borrow it from ADI"s disti, it"s about $300 for most demo board.

问：通过spi接口和spi解口的dac相连，如果dac是clk的上升沿接收数据，那么dsp发送
是应该采用上升沿发送还是下降沿？为什么感觉应该用上升沿，因为同步，你上升沿
发送我上升沿接收，不知道是不是这个道理？又想会不会又传输的延时呢？看了一本书上
说dsp用下降沿发送，没做过试验，不是很明白，希望给点提示，多谢了！

答： Transmit data is synchronizd on the risng edge.

Receive data is synchronized on the down edge.

问：DM203的开发软件“VisualDSP”如何得到？
另外BF533或者DM203的一些Demo代码如何得到？
答： It can be found under the Blackfin version of VisualDSP, part number VDSP-BLKFN-PC-FULL.  VisualDSP++ ships with a complete library of demo software available for evaluation and development.

问：开发工具支持27C512这样的EPROM吗?它能支持何种类型的存储器?
答： The VisualDSP package is for DSP code development and debugging.  It does not support EPROMs.  VisualDSP does ship with a "plug-in" module which allows programming of various flash devcies.  The plug-in allows the us
