| The
MLC3100A/MLC3110A has high performance
and flexibility for decoding MP3
compressed audio files (ISO1172-3
/ ISO13818-3) and CDROM format
(ISO9660) data. 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. The
MLC3100A firmware code initially
stays in external program memories
such as flash type memory or EPROM,
whereas, the MLC3110A allows its
firmware code to initially stays
in internal ROM. |
