I find a Reference Design in HDK of APEX Nios Dev. Board, called "IDE_demo":

<div class='quotetop'>QUOTE </div>

The IDE sample design includes a simple file system for demonstration

purposes. A single directory is supported, with named, byte-oriented files,

and a "write-once-read-many" model. (That is, bytes can only be added to

the very end of the very last file.) Sample perl scripts are provided that

convert text files into a file system image which can be downloaded to an

IDE hard drive.[/b]

I wonder who test it and apply it to some application? how about the performance?

This is in the Nios Dev kit? What version? I can&amp;#39;t find an example design for that.
