Smart-meter systems must meet significant technical challenges in order to lower manufacturing cost, power consumption and achieve high reliability. HCC has developed an advanced Smart-meter File System (SMFS) custom designed for the needs of smart-energy and smart-meter applications. This can result in lower cost of manufacturing, shorter development time, reduced field maintenance and longer guaranteed life of operation.
Instead of using a traditional file based system HCC has taken the radical approach of defining a system built around the needs of smart-meters. Metering applications usually have well defined record structures and HCC has used its’ extensive flash experience to take advantage of this characteristic. By taking a data focused, and not a file focused approach, it is possible reduce the required number of write/erase cycles by an order of magnitude. Traditional file systems do not have built-in cyclic buffer logic for storing records and this can add complexity, significantly increasing the number of times flash must be accessed. SMFS uses a structured database to reduce complexity of the application which can improve the performance in almost every way; speed, power consumption, and flash life.
