Neon power management / VFP power management

Note: This was originally posted on 24th December 2012 at http://forums.arm.com

hi, experts:

Does NEON unit have power management feature? (Similar to ARM core's DVFS function)

If NEON has power saving features, How about VFP unit?

If NEON has power saving features, so which doc will describe it?

Will NEON and VFP share some hardware funtions?(except for registers)

best wishes,

Parents

Again I can only speak for the processors I've worked with.... But my experience is that the NEON and VFP logic are in the same power domain. So NEON+VFP is powered, or NEON+VFP is not powered.
