Sorry if it's a re-post.
Lemarchand can talk about another interesting subject, though: the prospect that, in the near future, multi-platform PS3 games will outshine the versions running on rival consoles: "There's a set of tools called Edge that were developed on the Naughty Dog premises, actually, by a group of very, very senior games programmer, some from Naughty Dog and some from elsewhere. I think it's tremendously visionary of Sony to make these tools, which are largely low-level libraries."
Before proceeding, we need to explain a little of the unique manner in which the PS3's much-admired, phenomenally powerful Cell processor works. Essentially, it contains eight mini-processors called Synergistic Processor Units (SPUs), six of which can be given tasks to perform at any given time. Lemarchand continues: "It's code that runs on SPUs, and it's to do with things like animation compression, generalised compression and rendering optimisations. These guys are really old-school programmers: guys who are always looking to shave another cycle off an operation. And part of the skill of developing for the PlayStation 3 is getting the GPU to farm jobs out to the six SPUs – seeing which SPUs are idling and can take up some of the slack in a frame-to-frame kind of way."
