LSI combines USB/SD host, MP3 decoder, system controller

What is USB?
The Universal Serial Bus or USB is a communications architecture that allows a PC to interconnect various devices using a simple four-wire cable. A standard interface allows data rates of 12Mbps.

What is MP3?
MPEG-1 Audio Layer 3, more commonly referred to as MP3, is a patented digital audio encoding format using a form of lossy data compression. It is a common audio format for consumer audio storage. MP3 is often derided by audio purists for its lossy compression scheme, which discards audio data that's less noticable to the human ear in order to achieve small file sizes. A new format, dubbed MP3HD, is a lossless version that reverts to a generic MP3 file when there's no supporting codec for higher quality version.
