(Why Cortex-A9?, Performance, Specifications, Related Products, Resources)

The ARM Cortex-A9 processor delivers exceptional capabilities for less power than consumed by high performance compute platforms, including

• Unrivalled performance with 2GHz typical operation with the TSMC 40G hard macro implementation 
• Low power targeted single core implementations into cost sensitive devices
• Scalable up to four coherent cores with advanced MPCore technology
• Optional NEON™ media and/or floating point processing engine

Applications

The Cortex-A9 processors provide a scalable solution across a wide range of market applications from mobile handsets through to high-performance consumer and enterprise products by sharing the common requirements of:

• Increased power efficiency with higher performance for lower power consumption;
• Increased peak performance for most demanding applications;
• Ability to share software and tool investments across multiple devices;

Introducing the Cortex-A9

The Cortex-A9 processors are the highest performance ARM processors implementing the full richness of the widely supported ARMv7 architecture. Designed around the most advanced, high efficiency, dynamic length, multi-issue superscalar, out-of-order, speculating 8-stage pipeline, the Cortex-A9 processors deliver unprecedented levels of performance and power efficiency with the functionality required for leading edge products across the broad range of consumer, networking, enterprise and mobile applications.
The Cortex-A9 microarchitecture is delivered within either a scalable multicore processor, the Cortex-A9 MPCore™ multicore processor, or as a more traditional processor, the Cortex-A9 single core processor. Supporting the configuration of 16, 32 or 64KB four way associative L1 caches, with up to 8MB of L2 cache through the optional L2 cache controller, the scalable multicore processor and the single processor provide the broadest flexibility and are each suited to specific applications and markets.
