Two weeks after Intel signaled its future low-power intentions, ARM has unveiled its latest mobile chip design for smart phones and consumer devices that will arrive around 2010.
The Cortex A9 is an extension of the Cortex family of processor cores that ARM unveiled two years ago with the Cortex A8. It combines the multiprocessor support of older ARM cores with the Cortex design, ARM's highest-performance implementation to date. Several ARM partners, such as Texas Instruments, Samsung, STMicroelectronics, Nvidia and NEC Electronics also announced plans to use the Cortex A9 in future chips for smart phones and consumer electronics devices.

The Cortex-A9 processors have a dynamic length, 8-stage superscalar, multi-issue pipeline with speculative out-of-order execution. It is capable of executing up to four instructions per cycle in devices clocked at more than 1-GHz.
The Cortex-A9 MPCore processor supports system-level coherence with accelerators and DMA to further increase performance and reduce power consumption at the system level. The Cortex-A9 single core processor was developed for simplified design migration and reduced time-to-market of high-performance, cost-sensitive applications such as feature phones and other low cost embedded devices.Source: eetimes.com
