| shams said: In a way, they are correct. The architecture of the SPUs makes it very hard to compile/run AI on them - easily anyway (anyone know if there is a general C/C++ compiler for the SPUs?). But the game would have to process a huge amount of complex AI for this to be true. Only then would it soak up too much CPU on the main PS3 CPU (non-SPU), and result in a lack of cycles to drive the other processes (or control the SPUs). ... So - it could very well be true, or it could be a load of BS. Only a technical developer for Ubisoft (someone actually working on the game) would really know.

There is a general C compiler for the SPUs, and it has lots of useful specific functions to program efficiently (like performing SIMD operations and shuffling and what not). What the SPUs are especially bad at is traversing dynamically allocated data structures or accessing random places in memory, which can be important for AI.
With clever programming, you can offload some AI tasks to the SPUs, especially if you can batch them efficiently, put them into lists, that sort of thing.
