MIPS have been shipping 64-bit for years (multi-core etc), but why will ARM be successful when no silicon on the horizon for 2 years? AMCC is about a year later than initially promised. With a 64-bit SoC, power is important, but why would you need it for mobile? So much other stuff eating power, that the core might be less than 10%, so why choose ARM? Freescale has PowerPC 64-bit multi-core SoC, looking at ARM for A50. Too many architectural differences within ARM (and MIPS) camps. Architectural details still not readily available either.
I'm interested in Steve Furbers SpiNNaker neural simulation project. I guess there at the hardware ramp-up stage so havent yet done massive neural-net experimentation.
Its all blue-sky "who know where it might lead" stuff, but could be the first steps to "your AI buddy in your pocket".
