Intel's Atom processor has been stealing the limelight when it comes to small, portable Internet devices, but Intel rivals Arm and Texas Instruments hope to change that.

The two companies held a joint press conference a day before the start of the Computex trade show in Taipei on Monday to promote the use of their chips in mobile Internet devices, or MIDs, an emerging class of products that includes high-end smartphones, small tablet PCs and mini-laptops.

Arm and TI are already strong players in smartphones, but their products don't appear yet in mini-laptops like the Asus Eee PC, which is based on an Intel chip. But that will change by the end of this year, according to Seshu Madhavapeddy, general manager of TI's Mobile Internet Devices division.

He said that MIDs in all form factors -- including mini-notebooks -- will be announced by hardware makers this year based on TI's OMAP 3 processor, which uses an Arm core. Madhavapeddy would not name any of the manufacturers, however.

If those devices appear it will escalate the competition between Arm and TI on the one hand, and Intel, which coined the MID name and is hawking its Atom processor as the best chip for those devices. Indeed, as Intel tries to go "downmarket" with Atom and play a bigger role in the smartphone business, Arm, TI and other phone chip companies are hoping to move upmarket and challenge Intel in small laptops. At a separate press event here Qualcomm, another Arm licensee, announced similar ambitions.

"The OMAP 3 is great for all devices that need wireless connectivity, a full Web browsing experience and low power consumption," Madhavapeddy said, referring to TI's latest processor. "Whether it has a 3.5-inch screen or an 8-inch screen is irrelevant."

Arm and TI say their experience with the low-power and wireless requirements of mobile phones make them able competitors in the MID market. Arm's chip designs are generally less powerful than Intel processors, but Bob Morris, director of marketing for Arm's mobile computing segment, argued that processors based on Arm's new Cortex-A8 core use less power than Intel's Atom.

When a user puts a device into sleep mode, Morris said, the Cortex-A8 saves its last contents to external DRAM, which allows the Arm chip to shut own completely, conserving power. He claimed that Intel's Atom processor consumes a trickle of energy even when devices are asleep.

Arm will release an updated design, the Cortex-A9, next year, Morris said. It will be a multicore design, allowing manufacturers like TI to use up to four Arm cores on a single chip, he said.
