YAFFS talk - slides from a presentation to FOSDEM in 2004

Slides fom YAFFS - A NAND-flash filesystem. This was presented at FOSDEM 2004 (February 23rd), as part of the Embedded Track, and describes the YAFFS filesystem - its origins, how it works, explains the differences between NAND and NOR flash and thus why a specialised NAND-flash filesystem is appropriate. It also covers embedded-system use with Yaffs Direct, presents some performance stats, and a comparison with JFFS2, and looks at supporting next-generation NAND with YAFFS2.

YAFFS talk - Slide 1 - Title

YAFFS talk - Slide 2 - Intro

The areas covered by this talk: who's involved in the work on YAFFS, and how it got to the current stage, an explanation of the differences between NOR and NAND flash, then we'll look at the filesystem itself, covering the filesystem design, licencing, what you need to do to port it to a new OS.

We'll finish with some performance comparisons and the changes present in YAFFS2.
