<p>I have a ThumbDV here, which is an AMBE3000 chip mounted to a board<br>
with USB interface.<br>
http://nwdigitalradio.com/wp-content/uploads/2012/04/ThumbDV-A.pdf<br>
<br>
On the computer, it is accessed with a serial interface, or let their<br>
ambeserver software handle the serial and communicate with ambeserver<br>
over the network.<br>
http://nwdigitalradio.com/dv3000-ambeserver/<br>
<br>
Has anyone tried integrating this with OP25?<br>
<br>
The primary system I monitor is P25p2 (TDMA), but I am curious about<br>
DMR and Dstar as well.<br>
<br>
My goal is to offload voice decoding to this hardware for CPU savings<br>
so that lower power systems can be supported. I am also curious if it<br>
will improve voice quality, but this is secondary to CPU savings.<br>
<br>
Has anyone profiled OP25 to see where the CPU usage goes? I'm curious<br>
how much I could really reduce it by offloading voice decoding but not<br>
RF demodulation. I suspect it's working pretty hard on RF demod.<br>
<br>
If no one has tried this, can someone at least point me toward the<br>
right part of the code to inject support for alternative decoders?<br>
<br>
Tom<br>
