The method of one embodiment for the invention is for the CPU to read a subset
of consecutive pixels from RAM and cache each such pixel in the WC Cache (and load
corresponding blocks into the L2 Cache). These reads and loads continue until the
capacity of the L2 Cache is reached, and then these blocks (a "band") are iteratively
processed until the entire band in the L2 Cache has been written to the frame buffer
via the WC Cache. Once this is complete, the process then "dumps" the L2 Cache
(that is, it ignores the existing blocks and allows them to be naturally pushed
out with subsequent loads) and the next band of consecutive pixels is read (and
their blocks loaded). This process continues until the portrait-oriented graphic
is entirely loaded.
