在配有块写入图形存储器的系统中，该算法可以实现并行填充象素。

The algorithm foresees the pixels which will be activated in a raster line and implements parallel filling pixels.

但是，在这种情况下，根据图形对系统存储器带宽的定量，系统存储器或者图形存储器可能未充分利用。

However, in this case either the system memory or the graphics memory may be under-utilized, depending on the ration of graphics to system memory bandwidths.

因此，这种解决方案对于图形存储器性能足有益的，但一般比仅实现系统存储器的实施例具有更高的成本。

Therefore, this solution is beneficial for graphics memory performance but it would generally cost more than the embodiment implementing only system memory.
