HCC Embedded, a supplier of advanced embedded middleware for storage and communication, has developed an advanced file system that is custom designed for the needs of smart energy and smart meter applications.

The company reports that the Smart-meter File System features fail-safe data storage for system recovery, persistent data storage for 15 years or more, minimal power consumption to preserve battery life, minimum number of flash operations to preserve both the flash and battery, and deterministic behavior in the event of unexpected reset.

The software, HCC notes, is compliant with the MISRA C:2004 coding standard and requires less than 15 kB program memory and less than 1.5 kB of RAM on most 32-bit MCUs.
