Tuxera Flash File System brought to Integrity RTOS
With cars becoming increasingly smart and, data-driven, every element of the car – from ADAS systems and the cluster to IVI and intelligent gateways – is becoming more open to the outside world, explains Tuxera’s director of automotive business development, Severi Tikkala. This leads to new safety requirements for automotive storage and for the software to maintain it.
The Integrity RTOS is Green Hills Software’s flagship operating system. Widely used by automotive Tier-1s and OEMs, Integrity is built around an advanced partitioning architecture, and provides embedded systems with reliability and security to offer an optimum deterministic real-time response. The RTOS is certified to the highest levels of automotive safety (ISO 26262 ASIL D) as well as the highest security level ever achieved for any software product – Common Criteria EAL 6+, High Robustness.
As cars are becoming smarter, the automotive platform software has become complex, becoming write operation heavy and extensively interconnected with other elements of the car. This creates new requirements for the data security of the platform and makes long-term storage performance an important aspect of the file system that maintains it.
Designed for Linux applications, Tuxera’s Flash File System offers a full-scale set of features for automotive-grade data handling, including data-integrity functionality for tackling potential power loss scenarios, an added level of security utilizing encryption, prolonged lifetime of the flash memory by reducing the level of storage fragmentation to the minimum, and additional technologies, such as compression and boot-time optimisation.
Tuxera’s Flash File System, however, is not the first Tuxera storage software product to support the Integrity RTOS. Previously, the two companies have worked together adding Integrity support to a wide selection of Tuxera’s external storage file system implementations, including Tuxera exFAT, Tuxera NTFS, and Tuxera FAT, making advanced interoperable storage solutions available to the automotive sector.
