And as Gunnar explained, AMMX was simple to implement since its:
1. Pretty much a copy of intel MMX, so not a huge challenge
2. Well documented by Intel, advantage for coders
3. there are image and video codecs that are already optimized for MMX wich gives immediate benefits for Amiga usage as well..
