Texas Instruments Inc. expands its OMAP family of application processors with the OMAP 5 mobile applications platform. The company claims the platform is positioned to transform how mobile devices such as smart phones, tablets and other mobile form factors are used, making them even more valuable in daily life.

TI says the platform will enable a device which provides PC-like computing performance with mobile power levels that can be used to conduct a stereoscopic 3D video conference, project a document, edit the projected image on a surface, and play games on your HDTV using wireless display technology.

The OMAP 5 applications processors offer up to 3x processing performance and five-fold 3D graphics improvement, yet provide a nearly 60 percent average power reduction compared to a sample user experience on the OMAP 4 platform. Additionally, the OMAP 5 platform's software is designed for maximum reuse to ease migration from the OMAP 4 platform.

The OMAP 5 processors leverage two ARM Cortex-A15 MPCores capable of speeds of up to 2GHz per core in the OMAP 5 implementation. With a 50 percent boost in performance over the Cortex-A9 core (at the same clock frequency), combined with up to 8GB of dynamic memory access and hardware virtualization support, the Cortex-A15 core can enable true mobile computing experiences, such as the ones referenced above.

The OMAP 5 architecture combines many different processing cores that are tailored and power-optimized for specific functions. In addition to the two Cortex-A15 cores, the OMAP 5 processor includes individual, dedicated engines for: video, imaging and vision, DSP, 3D graphics, 2D graphics, display and security. The processor also includes two ARM Cortex-M4 processors for offloading real-time processing from the Cortex-A15 cores to improve low-level control and responsiveness of mobile devices.

Natural user interfaces
How we interact with the world around us in an intuitive, natural way is taken to the next level with the OMAP 5 platform's advanced support for S3D, gesturing (including proximity sensing), and interactive projection.
