Hey,
This is not a Radio per se. It's a modem chip built in the style of a modern Graphics
Card (GPU).
It's effectively a DSP chip under another name. It requires the frontend and ADC, from
an rtlsdr for example, before it can do anything.
This kind of device takes the fun out of SDR in some respects. The wonderful thing about
SDR as we know it is that modern computers are fast enough to do all the processing on the
CPU in real time (for many applications). This makes developing software etc far easier
since you can use languages and tools that you are familiar with, are easily debuggable
and don't require as much specialist knowledge.
That said, it might require less effort to program than one of the FPGA's onboard an
Ettus or something like that so for embedded systems it's an attractive proposition.
You might one day be able to flash your phone to make it into a TV receiver or something
like that.
Interesting stuff.

This chip is a Cell Phone Radio mostly for the 2 to 4
GHz band. The announcement below is a press release for the rollout of the chip to cell
phone manufacturers. The technical specifications are probably proprietary and any
development boards, if any, will probably be only for licensed developers, translation;
“for those who can afford it.” To HACK this device would require sophisticated Laboratory
equipment, again, it is all about money.

from Icera
Hello group,
What do you guys think of the nVidia Tegra 4's i500 SDR?

Is it hackable?
