Cortex-A9

The Cortex-A9 processor is a performance and power optimized multi-core processor and it is one of Arm's most widely deployed and mature applications processors.

Information on Cortex-A9.

Getting Started

The Cortex-A9 processor features a dual-issue, partially out-of-order pipeline and a flexible system architecture with configurable caches and system coherency using the ACP port. The Cortex-A9 processor achieves a better than 50% performance over the Cortex-A8 processor in a single-core configuration.
