VPf vector example

Note: This was originally posted on 5th January 2011 at http://forums.arm.com

Hi.

the cortex documentation speak about register bank for vector usage.
That's great, but I do not really understand what is a vector instruction (using those bank)

Does anybody can give me an example using the register bank and vpf vector instruction ?

Thank's

That is the older, deprecated "VFP vector" or "short vector" mode. It's not supported (in hardware) on the Cortex-A nor Cortex-R processors (as far as I know).

Details are in the ARM ARM for v5 http://infocenter.arm.com/help/topic/com.arm.doc.ddi0100i/index.html or v7-A & -R http://infocenter.arm.com/help/topic/com.arm.doc.ddi0406b/index.html
