Which MCU core Nokia & Samsung use???

[fireball003]

Hi,
While I was looking for the real applications of ARM7TDMI-S, I didn't get any clear idea. Is there any link describing specific devices that use ARM7TDMI-S core?

Which MCU cores Samsung and Nokia or other giant mobile or PDA companies use?

Do they all use ARM based MCUs? Or they use their own core based microcontrollers? If they use ARM cores then which ARM core most of the companies use in their devices?

Thanks.

Hi

About 2 years ago I found some advanced Nokia mobiles use ARM9
I think if you serch on nokia developers you'll find good information

I found searching over internet that the companies are somehow tell nothing about the processor cores that they use in their products.

Specially when I was trying to get the info on how to develop JRE for specific microcontroller I found no help from them.

Try GBA programming. That is an ARM based device.
eBook from **broken link removed**.

Not exactly Nokia / Samsung stuff.

But I did try some of the code in the eBook and downloaded to a GBA as well. They work. A funny way to learn ARM.

thanks

I used the download cable from liksang.

Development with GBA is not like development with a bare ARM chip or ARM development board that we can make thing work down to individual pin I/O level. Look at Jharbour website for HAM development kit, using gcc compiler with the GBA toolchain, compiled program for the color LCD screen as well as using sound from the GBA.

Nokia and samsung mostly use ARM9 or ARM7 processors.
TI came up with OMAP processors which is used in most of the nokia N-series phones as well as some android phones.
