The OMAP-DM270 multimedia processor is a highly integrated video and imaging engine offering excellent performance, leading-edge process technology, and flexibility for 2.5G and 3G camera phone applications. The OMAP-DM270 is intended for high-volume wireless OEMs and ODMs and is not available through distributors. The DM270 is a highly integrated, programmable platform that combines programmable image-processing capability with a highly integrated imaging peripheral set. The programmability comes from a DSP-based imaging coprocessor that enables manufacturers to implement their own proprietary image processing algorithms in software. The DM270’s flexibility is a result of the highly integrated architecture, which supports various types of CCD and CMOS sensors, signal conditioning circuits, power management, SDRAM, shutter, iris and auto-focus motor controls. The DM270 will allow handset manufacturers to meet customer demands by fulfilling both image quality, feature richness and low cost expectations required in current and future camera-enabled mobile handsets and PDAs.
