How do I go about picking an architecture ? My first thoughts suggested Cortex M3 but the more I look into it the less sure I am.
Obviously I don't to go to the trouble of learning a new technology only to find that I've made a bad processor choice (ie nearly end of line). I've spent many hours looking at many websites and have yet to find any high-level stuff on choosing my first ARM device.
If there's one thing wrong with ARM its the almost infinite number of devices
I'm an embedded developer wanting to undertake my first ARM project, so I'm completely new to the ARM architecture. I want a low power device with serial, USB and some ADC channels.

YES IT IS ARM MODE!
TRY IT UR SELF!

leave the compilers aside. can you provide a quote from the documentation founding your claim? how many times do I need to ask? come on, show us. I'm still waiting. If you can then I am wrong - not the end of the world. but you must show the quote first (I didn't find it).

i told u so many many many times b4 but u seem prejudiced aginst things i say.
look at
infocenter.arm.com/.../IHI0042C_aapcs.pdf
page 16
A subroutine must preserve the contents of the registers r4-r8, r10, r11 and SP (and r9 in PCS variants that designate r9 as v6).
it does not say must preserve r0-r3. dos it?
why does ity not say r0-r3? bcoz they do not need preserve.
i think i am correct
now plz. u reciover { and maybe apologise }.

I will not provide a quote but in this particular instance you are right - R0-R3 can freely be corrupted at any processor mode (I don't know the M3).
