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 with state-of-the-art progressive scan
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-
channel audio serial port compliant to I
2
S format for
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.
