This provides low cost devices for small systems using the ARM CPU. This group is to exchange information to help users get started and learn how to use the devices.
64 bit instruction support - "ICLI, Bekir (EXT)" - Mar 17 9:54:18 2008
Hi all,
I have just seen a text in the book "Arm System Developer's Guide" that says (page 106):
"ARMv5 adds instruction support for 64-bit load and stores. This is available in ARM9E and later cores"
My processor is AT91SAM9RL64, and looking at wikipedia (http://en.wikipedia.org/wiki/ARM_architecture) my core supports 64 bit operations.
Is that correct, or am I missing a small, but important point?
Mit freundlichem Gruß / Best regards
