The "next-gen audio" article on Gamasutra said 400 MP3 streams in real-time using MultiStream.They can run an updated autonomous security kernel in a sealed SPU ! D^8
(That means they'd need a 7 core SPURS, even less likely haha)
One of the rumors mentioned that the PS4 audio DSP can decode about 200 concurrent MP3 streams. I can't find an equivalent measurement for the SPUs, except that Toshiba showed a full Cell decoding 48 MPEG2 1080p streams.
If Sony CTO's last interview holds any weight *at all*, I am very curious about the "configurable logic" he mentioned, and how they intend to tackle the security issues given that they were thinking of some form of PS4 Linux (again).
A great example of the power of the Cell processor is that MultiStream can process 50 * 2 second convolution reverbs on one SPU in realtime. MultiStream can also decode approximately 400 MP3's on a single SPU in realtime." -- Jason Page, SCEE (Sony Computer Entertainment Europe)
