On benchmarking embedded Linux flash file systems

A Tracing Toolset for Embedded Linux Flash File Systems

NAND flash memory integration in the traditional I/O software stack of Unix-like operating systems (OS) was achieved without modifying most of the OS layers. In fact, one can dissociate two categories of flash memory devices: (1) those which intricacies are abstracted to the OS (e.g. SSDs, USB sticks), and (2) raw flash memory chips driven by a specific Flash File System (FFS) such as JFFS2 and...

On Benchmarking Popular File Systems

In recent years, Windows, Linux and BSD have become dominant operating systems in personal computers [1]. An essential component of the operating system is its file system. Although there are reports [2, 3] on evaluation of file systems under the same operating system, it is necessary to assess the performance of different file systems under their associated operating systems to help selecting ...

Benchmarking Real-Time Linux Implementation on Embedded Platform

This paperdeals with design, implementation and testing of real time drivers for I2C and UART processor controllers on Beaglebone Black. Embedded Board runs with Linux 3.8.13 and real time co-kernel, Xenomai-2.6.3. Beaglebone Black has cortex A8 processor with 1GHz frequency. Xenomai Real time driver Model(RTDM) drivers are made for I2C and UART processor controller and their performance parame...

A Flash File System to Support Fast Mounting for NAND Flash Memory Based Embedded Systems

In embedded systems, NAND flash memory is typically used as a storage medium because of its non-volatility, fast access time and solid-state shock resistance. However, it suffers from out-place-update, limited erase cycles and page based read/write operations. Flash file systems such as JFFS2 and YAFFS, allocate memory spaces using LFS (Log-structured File System) to solve these problems. Becau...
