About This Product

■What is PX5 FILE?

PX5 FILE The embedded FAT file system is extremely small and ideal for the most memory-constrained embedded devices. Extensive caching mechanisms (caching of logical sectors, FAT entries, and directory search entries) provide ultra-high performance. All caches are optional, allowing developers to control the size of each cache. PX5 FILE is rigorously tested with 100% C statement and branch decision coverage testing for each release. Additionally, it leverages pointer data validation (PDV) to verify the integrity of the stack and internal system objects at runtime. Finally, optional runtime fault tolerance ensures file system integrity after power loss. PX5 FILE is easy to use and implements the industry standard FAT file system format.

■Supports FAT 12/16/32

・8.3 and Long File Name (LFN) support ・Driver interface is simple read/write sector direct call format ・Native implementation of Linux file system API (open, close, read, write) Features of PX5 FILE

■FAST AND EFFICIENT

PX5 FILE has extensive caching features for optimal execution performance. Logical sector cache stores the most frequently used logical sectors and eliminates costly reads from physical devices. The FAT entry cache consists of the most frequently used FAT entries, reducing the number of FAT sectors read. Directory entry caching improves searchability of files and subdirectories by caching subdirectory entries. All caching (and required memory) is under full developer control.
