7.2.2 Software Library
(1) File System
Name
Multi Device File Access Library V03L01 (object for small MCU, Evaluation)
Overview
File system library for embedded system (abbreviated as MDF).
Used when you want to handle data a directory created by target devices by PC.
Facilitates data transfer between PC and devices because multi device data can be
managed by the same file and directory format used by the PC.
(2) MP3 Decoder
Name
MP3 Decoder Library for FM3 V01 Evaluation
Overview
MP3 audio decoder library for embedded system.
Decodes MPEG Audio Layer III (MP3) bit stream data and outputs PCM format bit
stream data.
(3) AAC Decoder
Name
MPEG-4/2 AAC LC Decoder Library (2ch) for FM3 V01 Evaluation
Overview
AAC audio decoder library for embedded system.
Decodes MPEG-4 and MPEG-2 AAC bit stream data and outputs PCM format bit
stream data.
(4) JPEG Encoder/Decoder
Name
JPEG Baseline Process Encoder/Decoder Library for FM3 V01 Evaluation
Overview
Image encoder/decoder library for embedded system.
Encodes and decodes image data based on the baseline process of ITU-T T.8 and
ISO/IEC 10918-1 standards, which are the still image compression standards.
Decode function only is used for the simple AV system board.
