Hardware, Embedded Systems And yet another item on the iPad? Are we serious? Yes, we are, since this one is about something that even geeks who aren't interested in the iPad itself should find intriguing. Steve Jobs said yesterday that the iPad is powered by an Apple A4 processor, but contrary to what many seem to think - it wasn't designed in-house at all.

In an interim period, non-x86 versions of Windows could run x86 in emulation, just like Apple emulated M68000 on PPC or like Digital emulated x86 in the Alpha version of NT. If a JIT-like strategy is used (similar to Digital's Fx!32) and the most common shared libraries are ported natively, the speed penalty doesn't need to be that large.


The speed penalty of running x86 applications in emulation on a low-power ARM CPU, such as could be found in a tablet device, would indeed be very large.

The emulated x86 applications would be completely unusable.
