Digital Media Processor 2

Product Brief

DESCRIPTION

The ES6425 Digital Media Processor 2 (DMP2) is a high

performance single-chip audio/video decoder for a wide

series of applications such as networked or non-

networked/flash memory media players. This second

generation of Digital Media Processor has an enhanced

performance engine to decode MPEG-4 video at D1

resolution w ith sta te-o f-the -a rt prog re ssive sca n

NTSC/PAL video encoder for brilliant and sharp, flicker-

free output to the video display.

At the heart of the ES6425 is the ESS proprietary

Programmable Multimedia Processor core consisting of

32-bit RISC and 64-bit DSP processors that enable

simultaneous parallel execution of system commands and

specialized multimedia decoding tasks. The ES6425

includes a memory controller which interfaces to 8-bit or

16-bit DRAM with up to 128-Mb capacity.

The ES6425 performs video processing to provide high-

resolution display of MPEG-1, MPEG-2, and MPEG-4

videos and JPEG photos. The integrated NTSC/PAL TV-

encoder provides composite, S-video, and YUV outputs.

The ES6425 includes an On-Screen-Display (OSD)

controller to provide a user friendly setup menu to enable

or modify the various audio decoding and video display

features. A CCIR656/601 digital video output port is also

present.

The ES6425 also performs audio processing for Wave,

MP3, AAC, Dolby

 Digital, and WMA playback along with

a 7-band graphic equalizer. The ES6425 has a multi-

interfacing to an external audio DAC and ADC. An S/PDIF

output port is also integrated for transmitting digital audio

streams.

A 16-bit host interface present in the ES6425 connects to

many different storage solutions including Compact

Flash

, Smart Media, xD-Picture Card, and IDE hard

drives. Similarly, a serial interface is built-in to interface to

SD

, xD, MultiMediaCard, and Memory Stick

devices.

The ES6425 is available in an industry-standard 208-pin

Plastic Quad Flat Pack (PQFP) device package.
