Re: [Discuss-gnuradio] nVidia's Tegra 4 has SDR - the i500 LTE soft modem from Icera

[Alex Zhang]

Can anybody explain the difference between this softmodem and other existing wireless baseband programmable processors? 

My understanding is that, also as Marcus mentioned, it provides more flexibility by this array of special CPUs instead of the prefixed functions/blocks, within this chip. Otherwise, it won't bring big novelty.

As to the ADC/DAC and RF part, maybe we need to wait for the whole SDR  solution to be unveiled.

I don't have high hopes for this specific chip - I guess the IC will be hard to buy and the modem feature on built devices will hard to hack, lacking source and documentation for its drivers, just as Android devices are hard for cyanogenmod developers to hack with.

But these news do give some hope, the hope that more accessible high-end ARMs chips like TI's and Freescales' will follow up and incorporate these features in the future. Indeed, I am already working on a beaglebone-based SDR and this would be great.

It looks to me like this SoftModem chip is just an array of speciality CPUs.  What I want to see is details of ADC/DAC and the RF-to-baseband
  transceivers -- those aren't part of the same chip.

Alex,

Dreams can come true – just believe.
