The second picture refers to the CSR chip as a "GPS Transceiver" -- it's a receiver, not a transceiver.  (It might seem picky, but it's amazing how many people think that the GPS chip in their smartphone transmits signals to the GPS satellites.)

For the GPS receiver, we can confirm that the parts are physically present in Glass.  As for their function, we can only speculate at this time.

The TI OMAP5 is an option for the next generation Glass, but the competition is very strong and would likely desire to displace TI in Glass.  In a November 14, 2012 article entitled, "TI cuts 1,700 jobs in OMAP shift", EETimes reported that TI were re-targeting their OMAP R&D away from mobile computing and towards embedded systems.  So, depending on how one sees the Glass, one could draw different conclusions.  Of course, it is up to Google to make that call. 

We first saw the OMAP4430 in devices starting in 2011.  While it has had a long life, there are currently far superior options available for new development work.

I have not seen mention of OMAP4 being EOL neither. Would be interesting to know what make you think the device is obsolete/EOL?

OMAP4430 appears to be "active". And could you share your thoughts as to why OMAP5 would not be an option for the next Google Glass?

Isn't the glass intended to be used in conjunction with a cellphone which likely has a GPS receiver?  Why does it have GPS?

LATEST ARCHIVED BROADCAST

What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.

michigan0 Sang Kim First, 28nm bulk is in volume manufacturing for several years by the major semiconductor companies but not 28nm FDSOI today yet. Why not? Simply because unlike 28nm bulk the LDD(Lightly Doped Drain) to minimize hot carrier generation can't be implemented in 28nm FDSOI. Furthermore, hot carrier reliability becomes worse with scaling, That is the major reason why 28nm FDSOI is not manufacturable today and will not be. Second, how can you suppress the leakage currents from such ultra short 7nm due to the short channel effects? How thin SOI thickness is required to prevent punch-through of un-dopped 7nm FDSOI? Possibly less than 4nm. Depositing such an ultra thin film less then 4nm filum uniformly and reliably over 12" wafers at the manufacturing line is extremely difficult or not even manufacturable. If not manufacturable, the 7nm FDSOI debate is over!Third, what happens when hot carriers are generated near the drain at normal operation of 7nm FDSOI? Electrons go to the positively biased drain with no harm but where the holes to go? The holes can't go to the substrate because of the thin BOX layer. Some holes may become trapped at the BOX layer causing Vt shift. However, the vast majority of holes drift through the the un-dopped SOI channel toward the N+Source,...
