| Abstract: | In order to save with codes which the remote control studied or down from the Internet,the intelligent remote control is designed which is with the SD card as the save medium.In order to enhance the speed that the singlechip runs the file system,which is simplified the format in terms of the FAT16,and the physical address mapping of the memorizer is established,read the efficient data of the SD card directly is adopted,and singlechip runs file system in high efficiency is realized.A solutions to extend the outside memory of small embedded systems is proposed. |
