EBS has been providing high performance FAT file system software to the industrial, scientific, and consumer products industries since 1987.

ERTFS

HIGH PERFORMANCE FAT32 FILE SYSTEM

ERTFS

The most reliable high performance embedded FAT32 file system available.

ERTFS Pro and ERTFS ProPlus

Goes beyond basic features to provide services not typically available from an embedded FAT file system.

ERTFS

Failsafe Operation

Failsafe Operating Mode

Failsafe operating mode protects the

volume structure in the event of a power

interruption or media removal

FEATURES


Efficient journaling system utilizes unique features of the FAT File

system

FEATURES


User controlled bundling of command sequences into one atomic operation

FEATURES


Transparent or User controlled Journal File Commits

FEATURES


High Speed 64 bit circular data buffers and data extract files

FEATURES


Callable zero copy routines extract data from the circular buffer and archive it to

32 or 64 bit linear files.

FEATURES


Rewind Mode - no copy

Archived data persists in both the archive file and in the record buffer until

it is overwritten.

FEATURES


Create burst mode data acquisition systems with deep buffer capacity

FEATURES


Create always-on data acquisition systems with periodic archiving

FEATURES


Eliminate fragmentation in always-on data and video acquisition systems
