ARM has already helped develop a prototype, implantable device for monitoring eye-pressure in glaucoma patients that measures just 1 cubic millimeter, CTO Mike Muller said at ARM's TechCon conference. At the conference the company also introduced its first 64-bit chip. The ARMv8 adds 64-bit addressing capabilities, an improvement over the current ARMv7-A architecture, which is capable of up to 40-bit addressing. The architecture puts ARM into more direct competition with Intel and its 64-bit Xeon processors."
Actual implementations (Score:3, Interesting)
It is worth pointing out that current x86-64 implementations are limited to addressing "only" 48 bits [wikipedia.org] so it's not like that ARM was way beyond the curve with their 40 bit address space (that's 1 TB).
