Smart Meter File System uses structured database approach to maximize flash life and reduce power consumption
Nürnberg, Germany 21 Feb 2014 – HCC Embedded today announced that it has developed an advanced file system,
custom designed for the needs of smart-energy and smart-meter
applications. HCC’s approach maximizes the life of flash, significantly
reduces power consumption, and provides a deterministic ‘emergency
write’ function, which reduces cost by allowing the on-board capacitor
to be as small as possible. Collectively the file-system features can
result in savings of many ‘cents’ for each meter, a highly significant
cost reduction in high volume manufacture.
The software is developed using high qualitydevelopment methodology and is rigorously compliant with the MISRA C:2004 coding standard. The HCC‘Smart-meter File System™’ (SMFS™) requires less than 15kB program memory and less than 1.5kB of RAM on most 32-bit MCUs.
Metering applications work with well-defined records that are more suited to a database approach. General-purpose file systems do
not have any cyclic buffer logic for storing records and this adds
complexity to applications. SMFS uses a structured database to reduce
complexity of the application and improve the performance of the system
in almost every way—speed, power consumption, and flash life.
Key features:- Fail-safe data storage for guaranteed 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 the battery.
- Deterministic behavior in the event of unexpected reset.
SMFS is available immediately for a range of 16 and 32-bit MCUs and
SOCs, and thanks to HCC’s Advanced Embedded Framework, can easily
integrate with any RTOS, toolchain or development board.
