sditto,

<< I want to get a better idea of cell phone architecture so I can see how others are using software to control the architecture. >>

Pretty good functional diagram of a (SIM enabled) Multimedia and Bluetooth capable CDMA handset on the second page of this PDF brochure for the Qualcomm MSM3300 chipset as a starting reference:

qualcomm.com

Unfortunately there is no equivalent document yet for the MSM5100 or iMSM5000 3G chipsets yet. There is one for the MSM5000 but some advanced 3G functionality is not in that chipset which will be the first to deliver for IS-95-C services.

Note that in a GSM phone (and CDMA phones of the future) there is a great deal of supplementary capability or functionality on the SIM.

sditto: Again that is a fine ambition for TXN, but there is one small (smile) difficulty, TXN has zero access to CDMA for itself - it bought a couple of small companies with such access.

And only CDMA is used for 3rd gen.

Please do not misunderstand, I respect and own TXN. But the assumption TXN (or Intel for that matter) will easily leave the Q in the dust, calls for a grain or more likely, a bucket of salt.

sditto,

As an example, I've read in the past day that INTC, ARM, TXN, and SNDK all expect to be in 100% of all cell phones

It is perfectly possible for at least two of the above to be in 100% of all cell phones.

ARM is incorporated into custom DSPs made by TXN for cellphones. INTC make the Strongarm processor. The only one that is always in there is ARMHY.

John
