20MP camera phones with 1080p camcorders not far away

Semiconductor company Broadcom says its new processor will provide cell phones with full HD 1080p camcorder capabilities and up to 20MP digital camera resolution with advanced features such as multiple shots per second, image stabilization, face and smile detection and panorama mode. The BCM2763 VideoCore IV will also render mobile games natively at up to 1080p and include on-board HDMI output for a console-quality gaming experience on large screen HDTVs.
Now that YouTube is supporting full HD 1080p video sharing and many consumers are using their cell phones as their primary digital camera and camcorder, Broadcom believes demand for higher resolution and more sophisticated image processing has never been greater. While at the same time, mobile games already need enhanced graphics capabilities.
"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,” said Mark Casey, Vice President and General Manager, Broadcom's Mobile Multimedia line of business.
Smaller than previous Broadcom chip, the 40nm CMOS processor also delivers lower power consumption than the 65nm designs. The BCM2763's highly integrated architecture is also cheaper to produce, so it should reduce the costs of newer handsets (theoretically anyway).
The power savings of the BCM2763 (20-50 percent) will allow four-six hours of 1080p video recording and eight-ten hours of mobile playback, and up to 16 hours of full HD playback over HDMI (provided the handset has sufficient storage).
Broadcom says only 490mW of chip power is required for 1080p camcorder H.264 High Profile encoding and only 160mW for 1080p playback. Only 160mW of power is required for mobile game graphics processing, supporting up to 1GP per second fill rates. In other words, the graphics performance should increase by a factor of 4x to 6x in comparison to the previous generation Videocore III multimedia processor.
Eight in one
The BCM2763 integrates the functions of eight chips including GPU and graphics memory, image signal processing (ISP) and ISP memory, video processing and video memory, HDMI and USB 2.0, 128MB of LPDDR2 graphics memory stacked in a single package.
Handsets using the BCM2763 processor technology are expected to reach the market in 2011.
