The next Generation of Application Processors

Current smartphones have an impressive amount of processing power, and its getting better yet.  Samsung’s new Orion chip has now been spotted running in the wild.  This is one of the first of the next generation of mobile Application Processors.

Nvidia Tegra

In 2008 a smart phone would have a ARM11 class processor running at around 500MHz.  The original iPhone, and the iPhone 3G used one made by Samsung running at 412MHz.  The first Android phone (the Google G1/HTC Dream) used a 528MHz Qualcomm MSM7201A ARM11 processor.  The original Nvidia Tegra CPUs also fall into this class.  We’ll consider this the first generation of the TRUE smart phones as before the iPhone, smart phones were of limited use, and rarely had things likely fully working internet browsing etc.

Qualcomm QSD8250 Snapdragon

The second generation of smart phones significantly increased in processing power.  These are the phones that we use today.  The majority of these run on some version of the ARM Cortex-A8 processor.  These processors are single core 600MHz-1.3GHz devices.  Perhaps the best known are the Apple A4 (Samsung Hummingbird), the Qualcomm Snapdragon (really a custom ARM core called the Scorpion similar to the Cortex-A8 crossed with a Cortex-A9), and the TI OMAP3 series.  Second generation Application Processors also have brought some pretty powerful graphics to phones.  These are integrated onto the same die as the Cortex-A8 and usually are PowerVR (Apple/Samsung and TI), Adreno (Qualcomm from ATI), or Mali (ARMs own GPU) based.

Samsung Orion ARM Cortex-A9 Dev Board

The smart phones of 2011 will begin using the third generation of Application Processors.  These are defined by being based on the ARM Cortex-A9, a faster and more efficient ARM core, as well as typically being a dual core (or better) device.  The TI OMAP4 series fits this description. Qualcomm will continue with the Snapdragon line, but bring it to a dual-core 1.5GHz chip. Apple is an unknown, but will likely up the speed of the A4, or add a core to it.  Samsung;’s Orion is a dual-core 1GHz A9 with a quad core Mali GPU.  It also packs 32KB of L1 cache per core and a full 1MB of L2 cache. Nvidia has the Tegra 250 already, which powers a handful of devices such as the Zune HD.  These processors will handily run full 1080p video, as well as drive external displays.  Your phone will soon be able to play movies on your TV.

ARM Cortex-A15 Eagle

What will the future bring?  ARM Cortex-A15, the Eagle, is a 2.5GHz quad core.  Hopefully it can run without depleting our batteries in an hour.
