Embedded file systems

A file system is used to categorize information, allowing it to be stored in separate files and folders. 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 products have patented methods to ensure data, volume, and metadata integrity, plus work across a wide variety of operating systems.

Tuxera Reliance Velocity

Our high-performance, flash-friendly file system for Linux and QNX. Designed to bring the ultimate performance, reliability, and longest lifetime to any flash hardware –  whether it’s UFS, eMMC, MMC, SSD, or SD.

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