ES3986
Digital-Audio Processor
ESS Technology, Inc.
DESCRIPTION
The ES3986 digital-audio processor chip is ESS
Technology’s highly integrated, optimal-quality, and costeffective single-chip solution for the emerging digital-audio
market. Its target applications include internet audio
platforms, MP3 CD players in boom box and combination
systems, portable MP3 CD player, etc.
Based on the programmable multimedia processor (PMP)
architecture, the ES3986 integrates softwareconfigurable 32-bit reduced instruction set computing
(RISC) processor and a 64-bit vector processor core. The
RISC CPU can be used in place of a microcontroller to
provide the functions of system management, user
interface, and peripheral control. The vector processor is
dedicated for audio-specific processing. In addition to
MPEG audio decoding, it will generate 3D sound effects,
and support karaoke features, such as key control and
echo. The chip also provides the voice-activated ADPCM
codec for voice recording and language learning through
MIC input.
The ES3986 supports a variety of CD servos directly to
provide the system solution of lower BOM cost and
manufacturing flexibility. With its low system power
consumption, the built-in antishock capabilities, and 16Mbit DRAM support, the ES3986 is very suitable for
portable audio applications.
Figure 1 shows a typical standalone system using a
MP3 player, where the MP3 stream from a CD-ROM is
passed to the ES3986, which parses the system layer
and decodes the audio layer. The decoded MPEG
audio and 3D sound enhancement is then passed to the
external audio DAC.
