Division with NEON

Note: This was originally posted on 30th September 2011 at http://forums.arm.com

Hi.

I have 4 unsigned 16bit values into a Dn register (or 8 into a Qn register)

[v1] [v2] [v3] [v4]

I'm looking for the code to finaly have

[65536 / v1] [65536 / v2] [65536 / v3] [65536 / v4]

into another (or the same) Dn (or Qn) register...
Thank's

Etienne

One option would be do what a compiler normally does for ARM; use fixed point domain VRECPE to calculate 1/v1, etc, and then multiply out rather than divide, and then renormalize.
