El Reg has El Scoop on Sony's much anticipated next-generation portable gaming device, the PSP. Reuters has more details.
Yesterday Sony revealed not only the prototype design of the PSP, but also that it might include mobile phone technology. Whether that's a WAN technology (like GSM/GPRS or CDMA) remains to be seen. Already confirmed for the unit is Wi-Fi, and Bluetooth remains a possibility.
The device uses small, DVD-like disks for game and application storage - similar to those employed by the Nintendo GameCube. Dubbed the Universal Media Disc (UMD), the name implies Sony may choose to extend the use of this format beyond the PSP to other products.
The PSP's tech specs are impressive indeed, featuring dual CPUs - a first for a mobile gaming device. The first unit is a 32-bit MIPS R4000 core with an SIMD unit - almost identical in architecture to the PlatStation 2. The second unit is also a MIPS R4000 core, and dubbed the "media engine." Both of these will be fabbed using IBM's 90nm technology.
Along with the dual CPUs, the PSP will feature dual graphics processors - one for 2D and the other for 3D graphics. The end result should be games more detailed than those on the PlatStation 2 - which is extremely impressive. These will be delivered via a widescreen 480x272 pixel TFT display and Dolby 7.1 multi-channel audio.
