The
MLC3100A/MLC3110A has high performance
and flexibility for decoding MP3
compressed audio files (ISO1172-3/ISO13818-3),
CDROM format(ISO9660), Windows
Media Audio(WMA) and Ogg Vorbisa
format. In addition to the decoding
audio format function, the MLC3100A/MLC3110A
provides function of analysis
of file systems such as Joliet,
UDF, UDF-Bridge on Packet/Non-Packet
format in which it helps users’
time-to-market system development.
The MLC3100A/MLC3110A employs
new cutting-edge and high performance
RISC-DSP CPU core, very efficient
and flexible firmware and multiplex
peripherals. No internal DAC (Digital-Audio-Converter)
is included.
The MLC3390 and MLC3190 integrate
programmable and approved ARM7TDMI™
as a system controller, MCS Logic
proprietary 32-bit RISC-DSP processor
for advanced multi-format digital
audio (MP3/WMA/Ogg) decoding,
low power dedicated hard-wired
CDROM decoder, On-chip SRAM and
ROM, versatile audio interfaces
and large number of GPIO (general
purpose data input output) ports.
Additionally, it provides function
of analysis of file systems such
as Joliet, UDF, UDF-Bridge on
Packet/Non-Packet format in which
it helps users’ time-to-market
system development. |
