Will Cortex A7 Accelerate Android?

Texas Instruments (TI) said ARM’s heterogeneous ‘Big.little’ architecture helps it accelerate Google’s Android operating system.

TI, which designs the popular range of OMAP system-on-chip (SoC) processors found in many smartphones told The INQUIRER that ARM’s newly unveiled Big.little architecture will help improve overall performance of the Android operating system.

Avner Goren, GM of OMAP Strategy at TI told The INQUIRER that ARM’s Big.little architecture, which uses Cortex A7 and Cortex A15 cores, addresses a different need than that of multi-core processors made up of identical cores.

Goren said, “We have been using heterogeneous multi-cores since 2002, we always had an ARM CPU coupled to accelerators for video, graphics, DSPs, image processing. This [Big.little] doesn’t change anything in this idea. On the contrary, it builds on this concept and it is another dimension. None of what was held here changes what we are doing in the rest of the system.”

Goren continued by saying that Big.little is a natural progression from the multi-core, accelerator-aided processors of yesteryear. “What we have held today doesn’t change the fact I would continue doing accelerators, DSPs, video accelerators and use [Cortex] M3s inside, but it changes what I’m doing on the high-level Android side.”

When ARM’s multi-core processors tipped up at Mobile World Congress earlier this year firms were banging on about it would be a golden age of power efficiency due to being able to run multiple cores at lower frequencies. Now less than a year later and with dual-core smartphones still having relatively poor battery life, it looks like that strategy has gone for a Burton. Goren admits that homogenous multi-core architectures do have a problem.

“Multicores give you scalability in a range, performance goes up and down within this range based on how many cores are active and what is the voltage level for these cores. On the other hand it has a floor, this floor is when you have one core running at the lowest voltage. What we have identified is a need for general processing power, meaning running Android, even at a lower [power] level,” said Goren.

Goren said ARM’s A7 processor will allow TI to ramp up the Cortex A15 core without hurting the ‘idle’ performance of the more frequently used Cortex A7 core.

Will Android Tablets Get Ice Cream Sandwich?

Google just held its Galaxy Nexus event in Hong Kong and we read just about every report and release in detail, only to find that Google didn’t even mention Ice Cream Sandwich Android 4.0 for tablets, which is somewhat surprising.

At this time, there is no official information if and when Android 4.0 comes to tablets. Since Android 4.0 looks like the lovechild of Gingerbread and Honeycomb and gets a few new options, it’s likely that we will see Android 4.0 on tablets, with a few tweaks of course.

Google just don’t want to talk about it, at least not yet. Since Google chaps already said that Android 2.3 capable phones should be able to run Android 4.0 this definitely applies to any Android 3.x tablets since most of them have dual-core processors and quite powerful hardware to back it up.

80 Million Tablet Sales Expected By 2015

The fortune tellers at Juniper Research have looked into their crystal ball and project that the number of annual shipments of tablet devices will reach 81 million by 2015.

The assumption is based on the fact that more consumer electronics and handset manufacturers will enter the market.

It claimed that Android is allowing both new and existing device manufacturers to enter the market and products have been launched already by companies such as Dell with the Streak, Maylong’s M150 and Samsung’s Galaxy Tab.

Anthony Cox, senior analyst at Juniper Research said that competition for Apple is likely to arrive in earnest in 2011.

Earnest may be a small town in Hicksville USA.  Cox thinks that by then Jobs’ and Co. will have launched another version of the iPad and will still be upping the bar.

Apple, as first to market with its compelling hardware and content combination, will maintain its market lead for the medium term, Cox said.

Products using QNX for Blackberry smartphones, Windows Phone 7 and MeeGo will come to market in 2011 and of course the netbook market will be pressured. However Juniper thinks that netbooks will remain resilient in the business market.  Read more….
