Framebuffer uses a video output device to drive a video display device from a memory buffer containing complete frame data. Note: Different from the traditional SPI protocol, the data line from the slave to the master is hidden since the device only has display requirements. Many of the above units can be used with the standard metric prefixes yocto, zepto, atto, femto, pico, nano, micro, milli, centi, deci, deca, hecto, kilo, mega, giga, tera, peta, exa, zetta, and yotta.
