[hpsdr] ozy / janus

Janus has a CPLD and it will be loaded with a useful image that allows 
it to function with the modified PowerSDR software.

Ozy has an FPGA and it has to be loaded each time you power up. 
Normally,this would be done through the USB port, but there is also a 
Flash configuration memory on Ozy that *may* be loaded with a runtime 
image.  Ozy is intended to use the USB connection in normal operation, 
so the FPGA's configuration Flash does not *need*to have any thing in it.

The intent is that they provide a high-end sound card equivalent to run 
an SDR such as the SDR-1000.  The prototypes are running with SDR-1000 
now...

Not sure what you want to hack, but Ozy is a good FPGA 
development/learning tool, and Janus is a good ADC etc.

The free Altera Quartus II tools are being used for FPGA development for 
Ozy and CPLD development for Janus.  You need a computer that will run 
these tools.  < URL:http://www.altera/com >
