Can this be really done?

Last week I spent sometime (re)searching various options for mobile signal processing. The findings are quite encouraging: there is a number of chips that can be used for our purpose.

Here is a brief summary of my findings:

  • there is a chip in Hong Kong that can be re-used without much of the firmware modification,
  • I also found several general purpose IC,
  • and finally, there is a family of very powerful powerful enough general-purpose chips but the codding for them is a ted bit involved.

What I liked about all these options is that the cost of the parts is below a few hundred dollars.

Details are in the follow up posts.
