Hello pragash.Thank you again. My question would be than could two different OS execute in a quad core Qualcomm SoC IC ? Also you had said you can clearly distinguish between LTE and WiFi and Bluetooth yes ? But would these front ends be required to be located on the top most layer of the SoC IC...
Hi pragash. Thank you for the response. I think I understand now the confusion on my part my apologies. OK here is my question. Take the example of the Qualcomm Snapdragon 400 model processor SoC. This dual core IC has an integrated modem (baseband IC) for cellular communications yes ? Now...
Hello pragash. Would you mind sharing which essential baseband IC RF components would be found on the die and what would be found off die likely close to the antenna (assuming the antenna is off die) ?
thanks a lot for the details.
Re: Can a multi core SoC with RF IO have two separate antennas
You can use the following Snapdragon IC's:

Can a multi core SoC with RF IO have two separate antennas
This question is purely hypothetical and just in theory but if you take a SoC such as the ones used for mobile devices and assuming this SoC has multi processor core but one common shared IO circuits (shared between each core) can each...
If you take some kind of transceiver SoC IC then de-cap it would it be possible to easily locate the areas of the die which will allow one to locate the leads which go to the off die antenna(s) ? Assume that you are working with just the die and do not know where the antennas are located off...
Brain just clarify the above comments. You are saying that it is rare to find a RF device (Tuned IC) using just a single frequency but rather a range ? Secondly you said "When viewing an actual module, the frequency is fairly easy to guess" yes ? Does this imply that by way of decapsulation and...
The reason for the interest is because I have knowledge of a company which is investigating certain hi tech devices which contain embedded RF technologies which may not be certified for use (if required) in the countries where these devices are being used.
It has been said that it is...
Hello betwixt. Thank you. Please do not be offended but would you mind if I asked if whether you are a RF engineer by profession ? I will understand if you do not wish to disclose the answer on a public forum. The reason I am asking is I would like to know from a RF engineer that using such...
My question is purely hypothetical and there is no immediate plans for any such application. But I was just curious is it possible to make use of the cellular frequency bands (as set out by a country's regulations and by the cellular providers) for some sort of covert type communication other...
Thank you very much ads-ee for the helpful reply. Can you please share whether flash memory or EEPROM or another kind of ROM on die would be as easy to locate as what you have described for SRAM ? Thank you.
The interest in the such details does not have anything to do with reversing to learn...
Ads-ee yes I am interested in the design layout of the embedded cores found on SoC and MCU from a reversing point of view (that is finding its location on die) and also the same interest in the NB IC. Thanks for the tip about reading up on the datasheet on the NB. I'll do just that. Would you...
Hello ads-ee.
Thanks very much for the above response. We have been searching Google for a while now just to confirm that the Northbridge chipset IC also contains an embedded core.
May we ask yourself including anyone else some further questions ?
Yes exactly we have discovered that a...
My apologies to everyone if this is the incorrect group for this topic. I was not sure whether it falls under digital signals or analog. I'm not an engineer not have any background in EE.
Could anyone familiar with the design of the die or of this IC belonging to any older model AMD or Intel or...
