EMMA Mobile 1

NEC Electronics has commercialised EMMA Mobile 1, an optimal system LSI chip for portable devices to process audio and visual data.

EMMA Mobile 1 integrates in a single chip all the functions necessary for playing multimedia data, such as ARM's high-end CPU core ARM1176JZF-S, high-performance DSP core for decoding digital signals of images and sound, as well as image display functions.

The chip is compatible with MPEG4, H.264, as well as VC-1 and is capable of D1 size (720 x 480 dots) video playback. Contributing to longer battery life, the EMMA Mobile 1 incorporates various technologies acquired through the development of M2, such as automatic clock control, on-chip power switch technology, and quick recovery technology.

The new device is also capable of playing various multimedia contents without any external components, by integrating built-in interfaces necessary for input and output of multimedia data, such as SD card interface, USB, SPI, UART, PCM, IIC, and NTSC/PAL. These features can be adapted to all kinds of embedded systems as well as portable devices.

The sample price of the new product is Rs.1,501.09 (US30$) per unit. Mass production is scheduled to begin in August 2009 and expected to reach 10 lakh units per month by 2010.
