Broadcoms VideoCore® Mobile Multimedia Solutions for Mobile Phones
The recently announced Broadcom BCM2727 VideoCore III mobile multimedia processor features on-chip advanced 2D and 3D graphics accelerators and efficient audio technology that provide a rich viewing and listening experience ideally suited for gaming applications on mobile handsets. The ultra-low power graphics pipeline is optimized for efficient hardware acceleration of the OpenGL ES 2.0 3D graphics standard and supports graphics rich 3D games with rendering performance up to 32 million triangles per second. Mobile games residing on the phone can also be played on televisions up to HD resolution via an included HDMI output, enabling a more versatile gaming experience.
Broadcom BCM2727 technology provides unprecedented levels of mobile multimedia processing to mobile devices, significantly raising the bar in terms of capabilities for digital video capture, high resolution still photography, and advanced 2D and 3D mobile gaming. It is the industrys first low power multimedia processor that enables high definition video camcorder and playback in cell phones and portable media players, supports an up to 12 megapixel digital camera, and delivers high performance yet ultra-low power 3D graphics for a world-class gaming experience. HD video, 3D games and high resolution 12 megapixel pictures can be displayed at top quality on full-sized HD televisions and monitors using an on-chip industry standard HDMI interface.
This groundbreaking multimedia technology adds a very significant competitive advantage to Broadcoms mobile platforms portfolio, enabling next generation cell phones to offer a quantum improvement in mobile audio, video, imaging, navigation and gaming experiences -- all with similar battery life and size as todays compact multimedia handsets. The BCM2727 also supports over fifty multimedia standards, formats, codecs and resolutions, and provides the broadest mobile multimedia content support in the industry. Its extremely low power enables over 6 hours of gaming from a standard cell phone battery, with the chip consuming only 130mW.
The BCM2727 multimedia processor provides high-quality multimedia features for mobile phones and advanced media players while retaining long battery life, a combination that allows users to carry a single device for all occasions. Next generation consumer devices based on the BCM2727 can support HD video camcorder and playback, professional cameras to 12 Mpixels with advanced ISP, and high-performance 3D for advanced user interfaces, navigation displays, and mobile gaming. Recording 720p HD video is supported in H.264/MPEG-4 AVC High Profile format, resulting in a quarter of the storage required versus MPEG-2 standards. While simultaneously recording HD 720p video and audio streams, consumption is around 450 mW, enabling HD camcorder record time of three hours for a typical system. Video formats including H.264, MPEG-1, MPEG-2, MPEG-4 ASP and VC-1 (for WMV) can be played directly without transcoding. The low-power VideoCore III architecture provides over five hours of HD video viewing or six hours of VGA playback. HDMI 1.3a with HDCP encryption and Component, S-Video, or Composite connects allow high-quality video playback on televisions. The BCM2727 delivers a high-quality imaging solution exceeding consumer portable digital cameras and approaching DSLR cameras. Advanced on-chip ISP is capable of handling sensors up to 12 Mpixels with on-the-fly image processing at 180M pixels per second and JPEG compression at 10 full quality photos per second. Even with reduced lens and sensor quality, crystal clear images with good color balance in a wide range of lighting conditions are enabled. Handsets are moving to high performance 2D and 3D features to deliver an immersive mobile user interface and to provide a gaming platform for high action, handheld gaming. The BCM2727 incorporates a tightly coupled 3D graphics hardware accelerator that provides a complete OpenGL ES 2.0 solution capable of 32M triangles per second and OpenVG 1.0 capable of 94 “tigers” per second. Battery life is not compromised with quality games consuming around 130 mW, providing game play time in excess of six hours.
