Texas Instruments Introduces the Power-Efficient OMAP4470 Applications Processor
Texas Instruments introduced the power-efficient OMAP4470 applications processor, designed to deliver the perfect balance between processing power, graphics, display subsystem functionality and multilayered user interface (UI) composition. The multicore OMAP4470 processor surpasses current market solutions with clock speeds up to 1.8 GHz, an 80 percent increase in Web browsing performance, increased memory bandwidth, a 2.5x boost in graphics functionality—via the POWERVR™ SGX544 core from Imagination Technologies—and a unique hardware composition engine. Mobile computing and gaming applications running on operating systems such as Android, Linux and the next version of Microsoft Windows will benefit from the OMAP4470 processor’s enhanced capabilities. Customers designing ultrathin laptops, tablets or smartphones around previously released OMAP 4 processors gain the added benefit of pin-to-pin hardware and software compatibility for maximum re-use and faster time-to-market.
The OMAP4470 enables customers to leverage tomorrow’s leading-edge display technology by supporting resolution up to QXGA (2048×1536). The new applications processor drives still more unparalleled HD UIs with simultaneous support for up to three HD screens and up to 2x more layered imaging and video composition than competitive solutions—a capability required by the sophisticated UIs of next generation operating systems. This feature is enabled by the combination of a hardware composition engine with a dedicated 2D graphics core, a highly sophisticated display subsystem, and dual-channel LPDDR2 memory enabling up to 7.5 GB/s of throughput to composite the graphics and/or video data output. This frees the GPU to perform graphics-intensive tasks such as gaming or widget creation while the compositing process is assigned to more power-efficient hardware subsystems.
Powerful enough for desktop applications yet highly power-efficient for mobile applications, Imagination Technologies’ POWERVR SGX544 GPU complements the OMAP 4 platform’s promise of high performance, low power. The OMAP4470 processor is the first OMAP offering to leverage the POWERVR SGX544. Combining the SGX544′s features with the sophisticated OMAP architecture enables TI customers to deliver a new set of applications to end-users, including DirectX-driven games and videos.
