Analyst: TI to sample chip with new Arm CPU next year

Texas Instruments will put Arm's Cortex-A15 chip design in the OMAP5 chip, an analyst says

Texas Instruments could implement Arm's latest Cortex-A15 processor design in a chip that could be built and sampled as early as next year, an analyst said on Thursday.

TI is a lead customer for Cortex-A15 and could use the processor design in the upcoming OMAP5 chip, which could ship as test samples next year, wrote Joseph Byrne, a senior analyst at The Linley Group, in a research note sent late Thursday.

Arm designs low-power processors for devices like smartphones and tablets, and licenses the designs to chip makers like TI. Arm on Wednesday announced Cortex-A15, which the chip designer says offers five times the performance over Cortex-A8 processors. The Cortex-A15 can run at speeds of up to 2.5GHz and can stretch to 16 cores in certain chip configurations. Arm said it hopes to put the chips in devices ranging from smartphones to servers.

TI spokeswoman Heather Ailara said future versions of the OMAP platform are under development, but the company cannot disclose whether Cortex-A15 is part of any design.

Nevertheless, TI is excited about the possibilities offered by the Cortex-A15 when combined with OMAP technology, Ailara said.

The company is anticipating potential battery power savings as high as 60 percent in certain usage scenarios. TI is also expecting to double or triple performance with the power savings.

Ailara said the company will provide further details about the new OMAP platform in the coming months. The company will also announce its plans around Cortex-A15 in the coming months.

TI is getting ready to ship its latest dual-core chip for smartphones and tablets, the OMAP4430, which is based on Arm's latest Cortex-A9 design. The OMAP4430 will bring features like 1080p high-definition video to mobile devices. It will operate at a clock speed of up to 1GHz and draw up to 50 percent less power than its predecessors.

Motorola's Droid X smartphone uses the Cortex OMAP3630 chip, which is based on Arm's older Cortex-A8 design.

Windows 10 for Business / Dell XPS 13

I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.

Ultimately, I think the Windows 10 environment is excellent for me as it caters for so many different uses. The inclusion of the Xbox app is also great for when you need some downtime too!

Windows 10 / Lenovo Yoga 910

For me, the Xbox Play Anywhere is a great new feature as it allows you to play your current Xbox games with higher resolutions and better graphics without forking out extra cash for another copy. Although available titles are still scarce, but I’m sure it will grow in time.

First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.

For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.
