We’ve now some more detailed information on ARMs new 64 bit ARMv8 processor and its strengths and weaknesses. For the most part it resembles the 64 bit architecture that Intel and AMD use, an extended 32 bit architecture with several hold overs. Perhaps the most disappointing is that ARM has the same 48 bit limit to virtual address space that the competition has. If ARM had managed to overcome the limitations of canonical form addresses, they would have something that neither Intel nor AMD could bring to the server room. ARM desperately needs somthing to offer that the competition cannot if they are to convince admins to move from a familiar architecture to a brand new ARM architecture; power savings probably won’t be enough. Drop by The Inquirer to read up on the improved exception levels and encryption acceleration of the new ARMv8 architecture.
"At the ARM TechCon conference in Santa Clara on Thursday, the top brass at ARM Holdings, the company that controls the core designs and licenses them to a slew of chip makers for modification in smartphones, tablets, and other embedded devices, showed off the new ARMv8 architecture. It’s an incremental improvement over the current v7 architecture, just like the 64-bit extensions to the original 32-bit x86 processors from Intel and AMD were."
