MicroOS® - Micro Operating System - e.Digital's proprietary MicroOS® is extremely compact, full-featured and highly customizable embedded operating system designed specifically for portable digital devices. MicroOS® manages data files as well as codecs, integrates security systems for content protection and handles uploading and downloading files to PCs. Important features include:
Power and memory conservation - eliminates the need for a high-powered CPU by paring down all code to run efficiently on a low-cost microcontroller preserving valuable memory for other applications.
Extends Flash memory capabilities - Memory management transparently deals with bad blocks, erase blocks, wear leveling and is independent of data and erase block sizes.
Advanced editing features - insert and delete allows editing of files by inserting material at any point without erasing what follows, and deleting of selected portions of a file without spaces, blanks, or silences being left behind.
MicroOS® is applicable to any product that utilizes flash memory or rotating media as its primary storage medium including:
Voice Recorders One and two way voice pagers Digital cameras Cellular phones Portable Internet music players Handheld PCs Set-top boxes Kiosks
MicroCAM™ - Micro Compressed Audio Manager - Embedded software platform enabling portable units to transparently manage multiple audio compression and decompression formats, and manage data buffering for rotating storage media by means of M4P2™ (Moving Media Memory manager for Portable Products) technology.
AMIS™ - Audio Manager Interface Software - PC driver for interfacing portable devices to various PC-based song managers.
TWIRL™ - Two-Way Infrared Link - Embedded firmware for bi-directional data transfer using high-speed infrared.
