Look for multi channel input microphone input multi-channel speaker output DSP

English:

Now my project is that I want to acquisition of voice in 4 channel parallel through 4 microphone input and do the related algorithm with the data of 4 channel audio data,  finally output the  data of 4 speakers through the 4 channel speaker. The output of the 4 channel and 4 channel speaker microphone input are independent of each other. But the 4 channel acquisition of the audio data is the need to carry out the relevant algorithm (algorithm for the adaptive algorithm), and then separate the 4 channel independent output.

My questions is as follows :

question one : For such applications, using which DSP I  can achieve the above functions, and please tell me the related development board ? Please recommend to me , thank you!!

question two:Can be extended in the above requirements, such as 8 channel microphone into, 8 channel speaker output?

question three:I'm looking for two DSP development boards at the website as follows:

http://www.analog.com/en/design-center/evaluation-hardware-and-software/evaluation-boards-kits/21469-EZBRD.html       ADZS-21469-EZBRD

 

The above two development board can satisfy my function ?

中文:

现在的项目需要实现从4个麦克风输入声音,同时并行采集4通道音频,并对4通道音频进行相关算法并通过4通道扬声器输出。这个4各通道麦克风输入及4通道扬声器输出是相互独立的。但是4通道采集的音频数据是需要进行相关算法后(算法为自适应算法),再分开4通道独立输出。

问题如下:

  1. 1.对于这样的应用场合,请问采用你们的哪款DSP能实现以上功能,以及相关开发板连接?请您推荐一下,谢谢了!!
  2. 2.能否在上述要求再进行扩展,比如8通道麦克风进如,8通道扬声器输出。
  3. 3.我这里参详了两个dsp开发板

上面的两块开发板能满足我的功能实现不??还有这个开发难度可以控制吗??PS:我们单位基本是采用你们的模拟产品线,但是DSP系列产品根本没用用过(基本用TI的),所以不清楚开发难度等。谢谢!!
