Sony's new handheld official specs...
As its CPU, PSP will make use of twin MIPS R4000 32 bit processors running at max 333 Megahertz. One of these units is referred to as the Media Engine, and is to be used for sound, movies and I/O management. In addition, the system will include a so-called VFPU floating point vector unit with calculation capability of up to 2.6 Gigaflops. This latter unit is meant for assisting the CPU in 3D calculations.
Sounds a bit like they're taking a play from Nintendo's (or is it SGI's?) book with the main/media CPU setup. With good management on Sony's part, this could provide for some pretty impressive middleware for developers to take advantage of. N64 may not have had a huge processing power advantage, but I'd imagine nobody was complaining about having an IrisGL/OpenGL-based graphics API to play with...
Multimedia support is big for the system. Sony announced MPEG4 support at E3, and now they've gotten a bit clearer, revealing that the PSP will use the AVC decoder, which has a high encoding rate. This will allow the UMD to store up to two hours of DVD quality video. Sound is also taking a high place on the system's feature list. The PSP will feature reconfigurable DSPs which can be rewritten allowing for support for the latest sound technology. Sony announced today compatibility with the ATRAC3 plus format along with AAC and mp3. In addition, the system will support playback of 3D and 7.1 channel sound.
In so many words: it has shiny FMV bits.
Sony is also promising the highest level of copy protection for these discs using DiscID and AES encoding technology.
I suppose it's not terribly insightful at this point to point out that a security system is only as strong as its weakest link. Microsoft uses RSA on Xbox discs, for crying out loud, and it's now possible (if a bit of a hassle) to defeat that scheme with
software. Anyway unless Sony can throw the boot ROM and main RAM into the same package as the CPU (unlikely due to manufacturing complications), they can throw around all the encryption algorithms they like and hackers will be all too happy to yoink the vector table or some other known entry point to take control of the machine. Still, like in Xbox's case, this will probably be an effective protection against some serious threats to the bottom line: unlicensed commercial publishing, mass-marketed copies, and counterfeits.
On top of all this is Wireless Lan. The system will include as standard IEEE802.11 wireless LAN. Sony had originally intended to make this an option, but game creators were pretty adamant about its inclusion.
Smart move. Without this, PSP is essentially playing GBA's game. By including this in the system rather than making it an add-on, Sony has equipped PSP with something that could tip the "social gaming" playing field (the reason Nintendo keeps making multiple versions of each Pokemon game) in their favor.
Notably absent are any mention whatsoever of the screen and power supply, two elements that can singlehandedly break a handheld design. My guess is that the sprinkling of "up to"s in the article reflects a lot of speed scaling, and developers will be encouraged to use as little of the system's processing power as they can get away with, similar to the situation with most battery-powered systems. The screen will probably be 320x240 (to make life easier for developers without making the system cost too much), frontlit, and a little larger than GBA's screen. Sony might be able to leverage its relationship with Toshiba to cut a deal on high-capacity Li-Ion batteries, who knows...
