According to wikipedia the ARM11 chips have "64 bit data paths" and toshiba seems to have a chip they claim has # Synthesizable high-performance 64 bit RISC architecture (ARMv6) # 64 bit ARM® Instruction Set http://www.toshiba-components.com/ASIC/ARM1176JZF-S.htm http://www.toshiba-components.com/ASIC/ARM1176JZF-S.htm though thats pretty much the only mention a quick search coughs up, so I wouldn't call it definitive, for one thing I don't know if the 1176 is in production of not. edit: the ARM website doesn't seem to mention 64 bit anywhere either so toshiba may be engaging in a rather creative definition of 64bit.
