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
quality development methodology and is rigrously compliant with the
MISRA C:2004 coding standard. The HCC 'Smart-meter
File SystemTM' (SMFSTM) 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.
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.
