uffs by Ricky Zheng: Ultra-low-cost Flash File System, designed for nand flash working in embedded system.
UFFS 1.1.0 typically consumes less then 200K ram for 1Gb(page 512)/4Gb(page 2K) NAND flash. It supports direct flash interface, works with or without OS.
-Tree Nodes: 16 * toatl_blocks
-Page Buffers: page_size(2048) * buffers (10 ~ pages_per_block)
-Block info caches: (14 * pages_per_block) * block_info_caches ( 5 ~ 20)
-Total Memory usage = Tree Nodes Page Buffers Block info caches Others(1~2K)
Fast booting
UFFS [uffs1.1.0.exe] read only one spare area for each NAND flash block to build up the in-memory nodes tree. Typically, UFFS - 0MB needs less then half second to mount a full loaded 128 MB(page size 512)/512MB(page size 2K) NAND flash.
Static Memory Consumption
UFFS 1.1.0 will allocate all necessary memory (see the table above) when it start up(mounted) and will not require more memory when you create new file/directories. It's very important for some real_time_system.
Superb Reliability
Guaranteed integrity across unexpected power losses.
Bad-block tolerant, ECC enable and ware-leveling
Nothing new for flash file system, but UFFS implements these in a simple yet effective way.
No garbage collection needed for UFFS
UFFS collect the 'dirty blocks' on the fly, no garbage collection needed.
Support direct flash interface, no operating system needed
UFFS can be build on top of direct flash interface, easy to be ported to any embedded system without OS required.
Fully tested
UFFS is fully tested on PC (via UFFS PC emulator). Moreover, UFFS is not just 'proof-of-concept' but has been successfully used in real world product for tens of thousands of copies.
