Engineers at NEC have developed a processor for mobile telephones that includes three ARM processor cores in a single chip, a moved aimed at improving the multimedia capabilities of mobile phones.

The MP211 chip was designed to improve the ability of mobile phones to handle multimedia functions simultaneously, said Masato Edahiro, a research fellow at NEC's silicon systems research laboratories.

In a demonstration in Tokyo, he showed the chip running a Java applet, a browser and displaying some video at the same time

Most mobile phones today have a single processor for handling the jobs required to keep the handset running and connected to the network. Some newer models use two processors, one for the wireless and radio functions and the other for applications and multimedia functions.

The MP211 chip goes a step further by providing what is essentially three chips-in-one, so that, for example, future handsets that process and display television images do not suffer image breakup when the phone is also receiving an e-mail.

The chip includes three ARM926 cores from UK chip design company Arm, each operating at 200MHz. One of the cores makes up part of a dedicated media processing engine that can handle images and H.264 standard digital video. The other two cores are used for applications such as running Java applets, the phone's browser, telephone book and e-mail client.

The processor will be sold by NEC Electronics, the company's semiconductor arm, and samples of the chip are due in January 2005.

The company expects sales to begin sometime in the first half of next year. This means the first phones with the chip could be available as early as the end of 2005.
