Since X86 SIMD version is optimized wouldn't it be possible to write a tool that convert X86 SIMD to Altivec/Velocity engine code so no need to write specific code for PPC. It maybe not optimal but maybe better than stuff written by non expert.
edit : just googled after my post see :
https://www.ibm.com/developerworks/com ... rPC%20AltiVec%20migrationedit2
Since the XBOX360 and Gamecube/WII/WIU do have PPC processors I wouldn't be surprised (since some have been hacked) that their multimedia player (Xmplayer? others?) are optimzed and maybe uses altivec.
Expert on the field are console or PPC Mac programmers. (maybe some ppc games where the source code has been released do have such player)
