Embedded system and monochrome bitmap compression method and host

The invention discloses an embedded system and a monochrome bitmap compression method and host. The method comprises the steps of carrying out statistics on pixel information in a monochrome bitmap, thereby obtaining a plurality of groups of pixel information, wherein each group of pixel information comprise color values of pixels and number values of the pixels which have the color values and are continuously arranged at pixel positions; and combining and recording each group of pixel information, thereby obtaining corresponding compression data. According to the system, the method and the host, the purpose of compressing the monochrome bitmap in the embedded system is realized, so a data size of the monochrome bitmap is reduced, and the storage capacity of a microcontroller for image data in the embedded system is improved; and moreover, in a process of transmitting the compression data to the microcontroller, the image data is transmitted with less time, so the data transmission efficiency is improved. 本申请
