[hpsdr] Embedded DSP

Three possibilities come to mind immediately:

1) < URL:http://www.soc-machines.com/product/P1_Specs/P1_Processor.html 
 > for about $125.  Uses free Linux-hosted tools.

2) < URL:http://www.tapr.org/kits_dspx.html > the DSPx is about $110. 
This was used in the Buccaneer project from VK6APH and VK6VZ featured in 
the July, 2005 issue of RadCom, and is used in the Pic A Star project as 
well.  Uses free DOS-hosted tools.

3) Microchip's dsPIC series are low cost and use free Windows-hosted 
development tools.  Not sure about a specific embeddable module. <

Disclaimer: I designed the DSPx and supply it to TAPR.
