ARM Readies Cores For 64-Bit Computing
snydeq writes "ARM Holdings will unveil new plans for processing cores that support 64-bit computing within the next few weeks, and has already shown samples at private viewings, InfoWorld reports. ARM's move to put out a 64-bit processing core will give its partners more options to design products for more markets, including servers, the source said. The next ARM Cortex processor to be unveiled will support 64-bit computing. An announcement of the processor could come as early as next week, and may provide further evidence of a collision course with Intel."
Cell phones with ARM CPUs and 512MB RAM already exist. That's a pretty big chunk of the 32 bit address space, so it seems to make a lot of sense to be ready for when it's exhausted.
What does 32 vs 64 bit cpu's have to do with ipv4 (32 bit) vs ipv6 (128 bit, not 64) address space? The whole IP scheme has nothing to do past the NIC. Even if your talking about storing IP's in memory or whatnot, it's just XXXX bit variable.
