Broadcom Corp. brings to market its next generation multimedia processor that claims industry leading performance and lower power in the top multimedia categories for mobile devices. The BCM2763 VideoCore IV multimedia processor uses 40nm CMOS process technology, providing higher integration, smaller footprint size and lower power consumption than 65nm designs.

With the higher integration and significant power savings from 40nm CMOS process technology, the BCM2763 multimedia processor features the most advanced mobile HD camcorder and video playback, up to 20Mpixel digital camera and photo image processing, and 1Gpixel 2D/3D graphics rendering for a world-class gaming experience. HD video, 3D games and high resolution 20Mpixel pictures can be displayed at top quality on full-sized HD televisions and monitors using an on-chip industry standard HDMI interface. Additionally, the BCM2763's highly integrated architecture reduces BOM to help drive sophisticated multimedia features into more affordable handsets.

The breadth and quality of Internet multimedia content is rapidly improving, with sites such as YouTube now supporting full HD 1,080p video sharing. Consumers are also increasingly using cellphones as their primary digital camera and camcorder, which is driving demand for higher resolution and more sophisticated image processing which is currently only available on advanced standalone camcorders and cameras. Additionally, newer graphics-oriented user interfaces and mobile games now require enhanced graphics capabilities.

The new Broadcom BCM2763 VideoCore IV multimedia processor enables best-in-class performance in Full HD 1,080p camcorder capabilities in a cellphone with significantly improved quality over current generation handsets which generally have VGA or lower resolution camcorders. It can support up to 20Mpixel digital camera with advanced features such as multiple shots per second, image stabilization, face and smile detection and panorama mode. It has the ability to render mobile games natively at up to 1,080p resolution, which in combination with an on-board HDMI output, allows a console-quality gaming experience on large screen HDTVs.

In addition to providing these capabilities on new handsets, the BCM2763 has improved power savings using a 40nm process without draining the battery or significantly reducing talk time. Additional ultralow power consumption features include 20 percent to 50 percent power reduction in comparison to the prior generation Videocore III multimedia processor; 4-6 hours of 1,080p video recording and 8-10 hours of mobile playback, with up to 16 hours of full HD playback over HDMI given sufficient handset storage.

it requires only 490mW of chip power for 1,080p camcorder H.264 High Profile encoding and only 160mW for 1,080p playback. As for mobile game graphics processing, only 160mW of power is required, while it supports up to 1Gpixel per second fill rates and improves graphics performance by a factor of 4x to 6x in comparison to the prior generation Videocore III multimedia processor.

The BCM2763 processor integrates the key functionality and components needed to drive advanced multimedia capabilities in new handsets. As a result of this high integration, the BCM2763 enables a lower overall BOM cost, enabling manufacturers to pass these lower costs on and introduce advanced features to lower tier phones than previously possible.

The BCM2763 integrates the functions of eight chips including GPU and graphics memory, image signal processing and memory, video processing and memory, HDMI and USB 2.0. 128MByte of LPDDR2 graphics memory is stacked in a single package.

The 40nm process enables reduced power, improved performance and reduced handset board space.

Benefiting from an existing VideoCore software code base and legacy architecture, manufacturers of phones and other consumer electronics devices can easily add these new VideoCore IV multimedia features to their products, allowing faster time-to-market.

Mark Casey, VP and general manager, mobile multimedia, Broadcom, said, "VideoCore IV is setting new benchmarks for performance, power consumption and affordability and is poised to drive advanced multimedia capabilities into new tiers of handsets. Supported by our comprehensive line of complementary cellular and connectivity solutions, our multimedia processor technology is the right choice for next generation mobile designs."

The BCM2763 is currently sampling to early access customers. Handsets using this new 40nm VideoCore IV multimedia processor technology are expected to reach the market in 2011.
