BTW I have something that is unclear to me, how come, for example, a device that uses an ARM Cortex-A9 dual core processor has a Tegra 2 processor? Does it have two processors (Arm Cortex-A9 + Tegra 2)?
The ARM Cortex-A9 is a reference processor - ARM don't actually manufacture anything, they just do the core design work. Different manufacturers (nVidia, TI, Apple, etc) then license these designs, add on some of their own stuff, and make the chips. The Tegra2, Apple A5 and TI OMAP4 are all A9 based. Qualcomm, I think, use their own design (though still using the ARM instruction set for compatibility reasons). Not sure about the others - Wikipedia will probably tell you more though.
