1.5.7 Display List
MB86290A is operated by feeding display lists which consists of a set of
display commands, arguments and pattern data for them. Normally, these
display lists are stored either in off- screen frame memory (part of
MB86290A’s local buffer) or host (main) memory that the DMAC of the host
CPU can access directly. MB86290A reads these display lists, decodes the
commands, and executes them after reading all the necessary arguments.
By executing this operation set until the end of the display list, all graphics
operations, including image/object drawing and display control, are
separated from the CPU. Of course, the CPU program can also feed the
display list information directly to MB86290A’s designated registers.
