1. OVERVIEW

1.1 - MP3 decoder engine

The MP3 decoder engine is able to decode any

Layer III compliant bitstream: MPEG1, MPEG2

and MPEG2.5 streams are supported. Besides

audio data decoding the MP3 engine also per-

forms ANCILLARY data extraction: these data

can be retrieved via I2C bus by the application

microcontroller in order to implement specific

functions.

Decoded audio data goes through a software vol-

ume control and a two-band equalizer blocks be-

fore feeding the output I2S interface. This results

in no need for an external audio processor.

MP3 bitstream is sent to the decoder using a sim-

ple serial input interface (see pins SDI, SCKR,

BIT_EN and DATA_REQ), supporting input rate

up to 20 Mbit/s. Received data are stored in a

256 bytes long input buffer which provides a

feedback line (see DATA_REQ pin) to the bit-

stream source (tipically an MCU).

1.2 - ADPCM encoder/decoder engine

This device also embeds a multistandard ADPCM

encoder/decoder supporting

different sample

rates (from 8 KHz up to 32 KHz) and different

sample sizes (from 8 bit to 32 bits). During en-

coding process two different interfaces can be

used to feed data: the serial input interface (same

interface used also to feed MP3 bitstream) or the

ADC input interface, which provides a seamless

connection with an external A/D converter. The

currently used interface is selected via I2C bus.

Also to retrieve encoded data two different inter-

faces are available: the I2C bus or the faster

GPSO output interface. GPSO interface is able to

output data with a bitrate up to 5 Mbit/s and its

control pins (GPSO_SCKR, GPSO_DATA and

GPSO_REQ) can be configured in order to easily

fit the target application.
