Method for compaction and storage of binary image of virtual compact disk-ROM in internal flash memory of microcontroller of universal serial bus key, involves copying only non-empty block and pool of block descriptors to target memory

摘要

The method involves identifying whether each binary block of an image of a virtual compact disk-ROM acts as an empty block or non-empty block. The empty block is separated and the empty block is passed to a subsequent block if the binary block acts as the empty block. A block descriptor for identifying the non-empty block, is generated. The block descriptor is stored in a pool of block descriptors. The non-empty block and the pool of block descriptors are only copied to a target memory i.e. internal flash memory of a microcontroller. An independent claim is also included for a method for decompaction of compacted data.
