Embedded file systems

A file system is used to categorize information, allowing it to be stored in separate files and folders. Embedded file systems impact the read and write performance of the physical storage, the integrity of the data stored, flash endurance or the lifetime of the memory hardware, and data and storage interoperability. For an embedded device, file systems need to be power, fail-safe. All our embedded file system software feature patented methods to ensure data, volume, and metadata integrity. We have a variety of file systems to meet your specific data workloads, use case, and reliability needs. Plus, our embedded file systems work across a wide variety of operating systems and bare metal.

Tuxera Reliance Nitro

Tuxera’s power-failsafe embedded file system designed for data-critical systems running Linux, VxWorks, and other operating systems. A transactional file system built to protect critical system and user data from corruption in embedded devices where power loss may occur.

Embedded storage & network enablement software

Flash management and flash translation layer (FTL) software

Physical NAND flash media uses a controller, plus software or firmware, to act as a standard block device. This software must manage correctible bit errors and perform wear leveling, while using additional regions and caches to deliver high performance. Tuxera’s flash management software features both static and dynamic wear leveling, plus an advanced error manager to provide the best lifetime. Patented algorithms deliver high performance and recovery from power interruption. What’s more, our modular approach supports easy changes to the flash hardware, allowing system designers to optimize their bill-of-materials costs.

Tuxera FlashFX Tera

Our intelligent embedded flash memory manager – or Flash Translation layer (FTL) – designed for high performance, cost efficiency, and versatile controls of data storage management on raw MLC/SLC NAND flash memory.
