framebuffer 中文意思是什麼

Then it studies the implementation, architecture and characteristic of embedded guis based on framebuffer, designs testing programs to test several embedded gui system ' s performances ( stability, efficiency ), and finally chooses qt / embedded as the development platform of the bsas. chapter 3 firstly briefly describes the embedded system hardware architecture, and then enumerates functions of system software

The hardware design is expounded in chapter 3, which include four parts. then we focus on how to merge them together in chapter 4, that is, porting linux to mc9328mx1, this includes several parts, the first part is flashloader which can be used to download programs ; and then, give out develop model of start - up guide code ( bootloader ) which runs before linux kernel and linux kernel ' s start - up analysis, also porting them to arm9 mx1 ; thirdly, we realizes the porting of lcd framebuffer driver based on deeply grasped linux device driver model ; fourthly, the rootfs ( file system ) ? ? cramfs is designed. then we give an example that based on the embedded linux in chapter 5, what we call automobile navigation, and discuss how to develop with our arm linux to meet the need of application, too
