Any hint would > be most appreciated :-) I'm almost exclusively using ARM's Architecture Reference Manuals (available only after registration in ARM's inforcenter): ARMv7-A: http://infocenter.arm.com/help/topic/com.arm.doc.ddi0406c/index.html ARMv8-A: http://infocenter.arm.com/help/topic/com.arm.doc.ddi0487a.c/index.html http://infocenter.arm.com/help/topic/com.arm.doc.dui0489h/DUI0489H_arm_assembler_reference.pdf Seems to be available without registration and has similar descriptions of neon and vfp instructions like the ARMv7-A ARM. I don't know any more approachable source off-hand. Janne
