Sony is to power its new PocketStation games PDA using the ARM7 RISC processor. The win, shared with Atmel, the ARM licensee that it is supplying the ARM 7 single chip controller, could produce a lucrative revenue stream for Cambridge-based ARM. Nintendo is thought to account for up to half of the business of MIPS, ARM's major rival for this sort of business. The SCPH-4000 PocketStation is designed for Sony PlayStation gamers on the move. Compatible software is downloaded from the PlayStation onto the PDA. The PocketStation will also include a clock, calendar and an infrared (IRDA) port. ®
