A file system module is also built, which can access files on a FAT32 partition. The two parts connect to form a complete system for working with files on Patmos. An emphasis is placed on modularity and ease-of-use, as the work is to eventually be integrated into the Patmos project. An optimal file reading speed of 250 kB=s and writing speed of 150 kB=s has been achieved." }
