We have developed an optimized assembler code for image conversion from YUV to RGB. The code is based on the paper “Optimizing YUV-RGB Color Space Conversion Using Intel’s SIMD Technology“  by Etienne Dupuis, but adapted for the ARM processor found in the iPhone.

The average processing time for a 480 X 320 frame is 0.012 s.
