ABSTRACT:
A limited resource computer such as one based upon an integrated circuit card (“smart card”) or embedded processor employs a full hierarchical file system consistent with desktop and laptop computers, thereby enabling the full execution of application programs. This hierarchical file system contains both files and directories and is consistent with the following limited resource computer considerations: small code size for implementation; compact representation; robust to errors due to loss of power and/or master clock signal; fast access and retrieval; and being appropriate for memory-only storage. Along with doubly linking each of the memory blocks, the present invention also includes an anti-tearing algorithm for data consistency protection in case either power or the master clock signal is removed from the limited resource computer before a write operation is complete. The anti-tearing algorithm is operative to ensure that data residing in any object of the hierarchical file system.
