Device independent unchangeable information about a frame buffer device and a specific video mode. This can be obtained using the FBIOGET_FSCREENINFO ioctl. struct … A framebuffer (frame buffer, or sometimes framestore) is a portion of random-access memory (RAM) containing a bitmap that drives a video display. It is a memory buffer containing data representing all the pixels in a complete video frame. Modern video cards contain framebuffer circuitry in their cores. … See more Computer researchers had long discussed the theoretical advantages of a framebuffer, but were unable to produce a machine with sufficient memory at an economically practicable cost. In 1947, the Manchester Baby computer … See more Framebuffers have traditionally supported a wide variety of color modes. Due to the expense of memory, most early framebuffers used 1-bit (2-colors per pixel), 2-bit (4-colors), 4-bit (16-colors) or 8-bit (256-colors) color depths. The problem with such … See more Video cards always have a certain amount of RAM. A small portion of this RAM is where the bitmap of image data is "buffered" for … See more A frame buffer may be designed with enough memory to store two frames worth of video data. In a technique known generally as double buffering or more specifically as page flipping, the framebuffer uses half of its memory to display the current … See more Framebuffers used in personal and home computing often had sets of defined modes under which the framebuffer can operate. These … See more While framebuffers are commonly accessed via a memory mapping directly to the CPU memory space, this is not the only method by which they may be accessed. Framebuffers have varied widely in the methods used to access memory. Some of … See more Many systems attempt to emulate the function of a framebuffer device, often for reasons of compatibility. The two most common See more
