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."
You can do all this with a 32-bit address space as well. The only thing that must be swapped is the data. All the code can have its own addresses, unless you plan on having more than 4GB of application code on your mobile device. 4GB should be enough for anybody...
I've got eight 8-bit AVRs and duct tape right here. That's almost the same thing.
