Memory Access
See also: All Points AddressableWhile 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 the most common are:
- Mapping the entire framebuffer to a given memory range.
- Port commands to set each pixel, range of pixels or palette entry.
- Mapping a memory range smaller than the framebuffer memory, then bank switching as necessary.
The framebuffer organization may be chunky (packed pixel) or planar.
