MAPs Ready For 2.5/3G Phones March 2003 Issue Published Date: March 01, 2003
Compliant with the current OMAPI standard, the Nomadik family of multimedia application processors (MAPs) is designed for use in 2.5 and 3G wireless products. The chips allow portable terminals to play music, take pictures, record video, and host two-way visual communication in real-time. They are based on the combination of an ARM926EJ-S core together with programmable accelerators that operate independently and concurrently to process the video and audio coding functions, including pre/post-processing. The processor core runs at up to 350 MHz on a 130 nm CMOS process and up to 500 MHz on 90 nm CMOS. The core includes cache, Java acceleration in hardware, and real-time debug support. The programmable audio accelerator includes industry-standard digital audio encoders and decoders including MP3, MPEG2-Layer II, MPEG2/4-AAC, Dolby Digital, and others. The programmable video accelerator runs H.263 and MPEG-4 codecs via proprietary technology. Other features include a standard baseband modem interface and software support for Symbian OS, WinCE, and Linux. For further information and pricing, contact STMICROELECTRONICS, INC., Lexington, MA.
