Actually, Neil is correct.  I had the great experience of
working on the tool chain for PlayStation2 a few years back.
And, yes, it was a fun project.  The Emotion Engine is the
MIPS core, the vector units and the arbiter. 
For more information on the Emotion Engine, check out the 
ieee.org website (they have a few good Emotion Engine tech
documents/papers).

The PlayStation2 MIPS Core does not have such instructions.
