Wilsonville, Ore. – Focusing on the needs of embedded multimedia platforms, Mentor Graphics Corp. has added a Safe File System to its Nucleus OS to provide power-fail resiliency for multimedia devices with resident NOR, NAND and DataFlash flash storage.
The new feature was added to help embedded devices which are susceptible to unexpected system interruptions, e.g., when a device's battery runs out. Such interruptions can cause a device to lose a sector or become non-operational.
Also reducing the need for field repair, the use of the Nucleus OS Safe File System makes available a complete new file system for use before any information is erased.
This allows the system to be rebuilt either in its pre-write form (as if the write had never started) or with the new modifications included. This is not possible to guarantee with a DOS compatible file system and with many other file systems.
While the concept is simple, flash devices can have long write and erase times. Mentor Graphics says the Nucleus OS Safe File System solution addresses this issue and provides fast boot times.The royalty free Nucleus OS – Safe File System for flash devices is available now.information and pricing for Mentor Graphics
