| Abstract: | On the basis of analyses of the code of system basic input output system (BIOS), the relation of system BIOS and the module of Logo is given, the key technologies of implementing Logo module such as selection, decompression, display of the image and integration in system BIOS are discussed. In order to implementing easily and accelerating the display of the image, an improved display method of personal computer paintbrush (PCX) image is presented and the detailed procedure of the implement of Logo module is given on the embedded system platform. |
