    Is there any A15 bigLITTLE in volume production?

    that is used in smart phones

    Supposedly A15 big.LITTLE targets 28nm
    Renesas is trying to sell its mobile division - nobody seems to be interested.

    "Renesas Mobile Introduces Ground-Breaking Quad Core ARM Cortex-A15/Cortex-A7 CPU-based Communication Processor with Integrated LTE Cat-4 Modem
    Delivering low-power and high performance for fully immersive browsing, gaming and rich multimedia experiences using ARM® big.LITTLE™ technology for smartphones and superphones"

    Japanese chipset manufacturer Renesas looks increasingly likely to sell its loss-making mobile phone chip business, acquired from Nokia in 2010 for $200 million.

    “Overseas is our main focus,” president Tetsuya Tsurumaru told reporters in Tokyo yesterday, notes Reuters, without identifying the firms his company was speaking to.

    A sale in Japan remained a possibility, he added, but declined to discuss whether any talks about a domestic deal were underway.

    Only last week the company said it will decide in fiscal 2013 whether to sell the troubled mobile business.

    Renesas, the world’s largest maker of microcontroller chips used in cars, has been in the red ever since buying the mobile unit and was forced to seek a $1.8 billion government-led bailout last year. The mobile chip division is part of its wholly owned subsidiary Renesas Mobile.

    The world’s leading maker of microcontroller chips used in cars will receive its state financing by the end of September, at which point it will be two-thirds owned by the taxpayer-funded Innovation Network Corp of Japan (INCJ).

    Reuters notes that Renesas had been expected to join an all-Japanese merger of Panasonic’s and Fujitsu’s LSI chip units, which make microchips used in TVs, digital cameras and other consumer electronic products. It is believed that those talks are ongoing.

      Yes, Samsungs version of the new Galaxy.

    • YOu can list many companies that will come & go using ARM...
      just like TI... ?
      I think we are starting to see a trend (I listed additonal cases like STM and Freescale which you seem to ignore)
      Renesas (though you might not be aware of it) is not some Mickey Mouse company.
      Did anybody buy TI's OMAP A15 big.LITTLE design?
      It got excellent reviews - might be even better than Samsung.
      ARM is NOT a rubber stamp because it's becoming pretty obvious that a generic off the shelf design won't cut it. . Both TI and Renesas put in extra efforts and it seems it still won't cut it.
      I suppose that's why ARM is "reaching out" to second tier ARM customers....
      Even worse - Samsung can't get it right using its own process and fabs.

      It cracks me up - but Samsung is taping out 14nm FF....according to East

    • ZTE announced they will be using Tegra 4 in a smartphone....
      NVidia re-synthesized the LITTLE A15 in Tegra 4 for power-saving CPU....

      YOu can list many companies that will come & go using ARM...
      btw, besides INtel... how are the other x86 companies doing...
      Let's see... VIA does x86... but now doing ARM
      AMD announced it's going ARM...
      And if you take your head out of the sand... you'll find even INtel does ARM...

        Oh please...big.Little is a desperation move by arm to try to fool the world into thinking they still have the power advantage. It will never scale...what are they going to do next? pair 4 A15s with 4 A54s on the same SoC? Ridiculous. Qualcomm is not implementing big.Little because it will never scale. Why waste time and energy designing something that you can't build upon? With the A15, the power advantage arm had is over. The game is over. And warren west, the con artist, has skipped town

        bacbacker you sound like wallis?:)

        Big/little isn't an after thought, it was designed from the very beginning. It's a very elligent solution to the power/curve problem and *if* it works in the real world it will change the way mobile CPU's are designed. You can't pair A15s to A57s, for big/little to work both CPU's have to share the same exact ISA. It'll be A53/A57 for the next generation (the A53 will be the worlds smallest 64bit cpu).
