I hear Nok said they would not buy q's chips in Friday's cc. They said they would stay the course with their own despite the problems.

Can anyone confirm this?

Ok....I think I need to go over my general understanding of the DSP/ASIC usage in a cell-phone.

QCOM MSM....

Qualcomm uses an in-house DSP core which is combined with an ARMHY ASIC core. The two cores are manufactured in one chip (the MSMxxxx) by a foundry (IBM). The ASIC portion of the chip is used to perform certain CDMA operations which the DSP core cannot. The DSP is used for ancillary operations (non-RF).

Nok GSM chips....

I'm not exactly sure why GSM phones are said to run on DSP's since they use a similair set-up to CDMA phones which supposedly run on ASIC's. According to the following post by Molloy, the GSM protocol stack is run-on an ASIC core while other operations are run by the DSP.

Subject 29581

My (current) understanding is that TXN sells the DSP cores (the C5000 series) to Nokia....however they also act as the foundry to combine the core with Nokia's in-house (or ARMHY/MIPS) ASIC to make a GSM chip. They may also be doing this with Nokia's CDMA chip....who else would be acting as the foundry? Nokia has no semiconductor operations that I know of.

Will TXN actually need a W-CDMA license, if they are selling a DSP core which is not performing any CDMA operations and also acting as a foundry? Not sure....however it seems to me that any advances in TXN DSP's will likely end up in Nokia's whole line-up.

Of course all of this information is simply me attempting to rephrase stuff that various technical gurus have posted....hopefully I am not to far off. I really wish I had occasionally gone to class in college ;-)....
