The new team was tasked to turbocharge typical ARM designs that were "maxing out" at about 500MHz, which isn't enough speed to deliver the experience that Qualcomm is aiming for. (Intel's Atom for Netbooks, by comparison, now maxes out at 1.6GHz.)

"There was a need to go do something beyond this. So, we went and got the architecture license (from ARM) and we have this team of about 50 CPU designers and we put them to task. So, four years and $350 (million) to $400 million later, we have a CPU that actually works better than the (typical) ARM CPU."

The piece de resistance of this strategy is the Qualcomm QSD8672 dual-core Snapdragon that features two CPU computing cores capable of 1.5GHz performance, and a host of other features includes HSPA+, up to 28Mbps download speeds, 1080p high-definition video, Wi-Fi, mobile TV, and GPS. The graphics core is based on Advanced Micro Devices' ATI unit's technology.

Qualcomm is able to achieve this relatively high speed (1.5GHz) for a low-power processor because it did more than simply get a license from ARM. "We went and got an architecture license from ARM. The architecture license was for their new instruction set, the V7 instruction set. There's a difference between getting an architecture license and just getting a core license. A core license means ARM does the (chip) core and they give it to you. The architecture license is different: the actual implementation is your own," he said.

The 45-nanometer processor will be built by Taiwan Semiconductor Manufacturing Company
