eCosPro-MMFS MultiMedia File System

eCosPro-MMFS is an optional middleware package for the eCosPRO RTOS that provides a high performance filesystem specifically designed for streaming high volume and time critical data.

Typical markets for eCosPro-MMFS are personal video recorders (PVR), set-top boxes (STB), harddisk based video cameras, instrument recorders, personal radio recorders (PRR), video surveillance applications, multi-room video and audio, and similar high volume streaming applications.

eCosPro-MMFS provides both random access and streamed reading and writing of files. Streams support simultaneous reading and writing, and read position skipping. This latter functionality facilitates the implementatiom of PVR features such as pause, fast forward and reverse viewing of live video.

The filesystem has been designed to provide near optimal throughput for modern hard disk and disk interface implementations. The performance of the filesystem not only enables improved functionality to be delivered to the end user, but also provides the opportunity to specify lower performance and correspondingly lower cost disks, whilst still meeting application performance goals.

Suitable for deployment in sealed-box consumer designs and other high reliability applications, the filesystem features automatic self initialization, self checking, and self healing. eCosPro-MMFS is shipped as an integral part of NXP STB220 set top box development kits.
