TI’s new OMAP 4 platform supports development of planned features for the Smartphones, Tablets and other multimedia-rich mobile devices of tomorrow with tremendous performance and programmability to support new applications yet to be imagined.
Texas Instruments‘ (TI) OMAP™ 4 mobile applications platform will redefine the mobile device of tomorrow with new, innovative user experiences driven by PC-like web browsing, 1080p full HD video record and playback, intuitive user interfaces, location-based services and next-generation social networking applications. The OMAP 4 platform includes applications processors, a comprehensive software suite, power management technology and supporting components to bring next-generation Smartphones, Tablets and other multimedia-rich mobile devicesto market quickly. The platform is future proof, offering the programmability and performance headroom to support new and emerging applications and standards. Not only will the OMAP 4 platform acceleratetime to market and reduce research and development (R&D) time and costs for handset manufacturers, but its flexibility and openness will enable manufacturers to deliver innovative applications at breakthrough mobile computing performance. TI tests the OMAP 4 platform for real-world use cases, accelerating time to market and enabling stunning user experiences.
At the heart of the OMAP 4 platform is a powerful system-on-chip that includes the perfect balance of power efficiency and high performance. The OMAP 4 processor balances processing across four main engines: a programmable multimedia engine based on TI’s C64xDSP and power-efficient, multi-format hardware accelerators; general-purpose processing based on the dual-core ARM Cortex™-A9 MPCore™ supporting symmetric multiprocessing (SMP) and capable of speeds of more than 1 GHz per core; a high-performance programmable graphics engine; and an Image Signal Processor (ISP) for unparalleled video and imaging performance.
The OMAP 4 family includes two applications processors, both based on the dual-core Cortex-A9 MPCore general purpose processors: the OMAP4430 operates at up to 1 GHz, while the OMAP4440 operates at up to 1.5 GHz. Both processors offer the full variety of subsystems and applications discussed below to deliver hardware and software system solutions that scale across customer roadmaps optimizing time to market, flexibility and R&D efficiency.
