Dual core processors for mobile devices? ARM dual core chips for iPhone, Palm Pre next year
CNET is reporting that ARM, the company responsible for designing the architecture behind most mobile comuting CPU’s said that mobile phone makers will be delivering devices that run on ARM”s latest dual core CPU’s as early as next year.
They are referring to the ARM Cortex-A9 MPCore application processor. According to the ARM site, the new chip deisgn will provide faster processing with lower power consumption for all but the most CPU intensive applications.
“The Cortex-A9 MPCore processor is the first ARM processor to combine the Cortex application class architecture with multiprocessing capabilities for scalable performance and provides enhanced multicore technology that includes:
- Accelerator Coherence Port (ACP) for increased system performance and lower system power
- Advanced Bus Interface Unit for low latency in high bandwidth devices
- Multicore TrustZone® technology with interrupt virtualization to enable hardware based security and enhanced paravirtualization solutions
- Generalized Interrupt Controller (GIC) for software portability and optimized multicore communication“

There are already phones on the market that make use of the ARM A9 single core chip, namely the LG Renoir shown at CES in January (video here). The phone looks great in the video; the ARM Mali-55 GPU really makes the user interface smooth, with Vista like windows features. Without the phone in hand I can’t comment direcltly, but I imagine streaming video would look very nice on this phone. Of course, this phone is not available in the US (why would it be?) but it has some amazing features – 8 Megapixel camera, touch focus, several still shot modes, Dolby Mobile, DivX playback, Slow-Mo video recording, GPS, 3G, WiFi and will play Flash. It is so irritating the the US mobile companies are just shamefully behind the curve with mobile devices. I have to believe that most people don’t know what they are missing, so they don’t know to complain.
Since ARM is just the chip designer and not the manufacturer, it’s difficult to tell exactly when these chips will hit US phones, but if CNET is correct, we could see the chips in new phones next year. If true, then I will NOT buy a iPhone 3GS until I know what Apple is doing with regard to the new ARM design. Why would you invest in another 2 year contract when you know that the new chip is out there? If they combine the CPU with the updated GPU chips, then the iPhone’s sluggishness could go away completely. Now that might be worth $199.
