The PS3 is going to have a real OS available at all times to perform a large variety of tasks and play games all at the same time.

Second, quoting ars about console hardware/development...just no.

Third, any of these figures are current pre-release MAXIUMUMS that will be coming down by the time the system ships in a few months.

This will allow registers to be reserved to OS use without conflicting with the PPE's backward compatability.

The DMA-style memory access should take really good advantage of the RamBus memory since the bursts should be nice, long, and sustained.

The SPE is nothing more than an FPU on steroids, why on hell's name would any one use it as an OS? If there is an OS in the PS3 will have to run on the main PPC core... While we are at it, let's just come with better rumours shall we? Heck, I predict they will use the NVDIA gpu for OS related tasks... yeah, that is the ticket.

Do any of these technical rumour mills even have the slightest idea what a computer is and how it works?

I dont trust this recent rummor since javiercero1 pointed it out pretty obviously, spe's are not cpu's, they would be bad at running any type of os from the information we have already.

Its only limitation is that its addressable memory is tiny (256KB) --- access to main memory is modeled as an I/O operation (commands to the DMA controller). Now, that is not to say it is particularly fast at running general code, but the Sony OS won't be running just on the SPE --- the SPE will be used for secondary tasks like file transfer, networking, security, DRM, displaying an informational console, etc. The PPE will be reserved as much as possible for game code, since its the only thing in the chip with something approaching passable performance on general integer code.

So far the PS3 is a media centre, DVR, linux station and possibly a gaming device all for $???. How anyone can say anything about the PS3 yet is beyond me. It's a huge box full of bits that only a rare few have touched. Sat, 15 Apr 2006 20:50:00 GMT donotreply@osnews.com (Kroc) Comments http://www.osnews.com/thread?115520 http://www.osnews.com/thread?115520 Any modern game console meant to offer services beyond classic monolitic games, needs an operating system of some kind, and naturally it has to use some part of the hardware. Speculating on "lost performance" isn't that interesting. When the services of the system are finalized and public, we can assess the cost/benefit.

Part of the PS3 software/firmware will have to run on the PPE, since that's where most (all?) hardware interrupts for things such as network and game interaction devices are likely to be coming in, and where the equivalent of device drivers will be called from.

The part of the PS3 software/firmware that provides system services in audio/video encoding/decoding, or encryption/decryption, is likely to be run by one or more SPEs.

There's nothing odd about this at all. The system and the games will (most likely!) share the hardware resources through means provided by Sony's operating system and their software development kit. Just like any other operating system.

The SPEs are meant for the computation intensive kind of work common in media applications.

Whether it's part of the game, or part the Sony OS doesn't matter. It's the end user experience that matters.
