OT: Atmel Targets Image/Video/Audio Playback Applications such as TVs, Displays and Projectors with Introduction of New Processor Family
AT76C113P Device Integrates All Playback Functions Onto a Single Chip
SAN JOSE, Calif., Jan. 20, 2004 -- Atmel Corporation announced today the introduction of a new family of playback media processors suitable for Standard and High-definition TVs, flat-panel displays, projectors, and standalone playback boxes.
AT76C113P integrates all the functions required to implement playback functions onto single chip. The device contains a high-speed flash card interface that allows quick access of high-resolution images, video and audio streams stored in flash cards by digital still cameras. The media streams are then decompressed, processed and presented to the user overlayed with high-quality graphics.
AT76C113P device can generate full resolution images that can be displayed to HDTVs, LCD, and PDP displays. This allows the user to enjoy the images at their natural full resolution. It can also scale down images to NTSC/PAL resolution suitable for display in standard definition TVs. The device also has a USB host capability that allows direct reading from digital still cameras for archiving purposes, as well as reading of data from USB stick memory cards. The AT76C113P is available with and without USB hosting capability.
The device has an integrated ARM7TDMI processor that controls the entire application and manages file-system, decoding, and display functions. AT76C113P devices support all flash card interfaces including Secure Digital, MMC Multimedia, Memorystick, Smartmedia, CompactFlash, and Atmel Dataflash cards. In addition, all necessary peripherals including TV video output, USB, UART and SPI, digital audio interfaces to minimize the total system cost. Digital-to-analog converters have also been integrated to playback audio from video clips without external components. The AT76C113P device offers several new features compared with its predecessor products: Higher speed ARM subsystem running at 80MHz, integrated video encoder with line driver, hardware rotation function, unified memory architecture, and fast flash card interfaces.
The AT76C113P device supports audio and video decoding of MPEG1, MJPEG, as well as most popular video formats found in digital still cameras. It can also decompress audio files, including MP3, through a high-resolution digital audio interface. The decompression speed of 75ms per megapixel, combined with the high transfer rates to flash cards, can achieve quick rendering of even large, high-resolution images.
