Abstract: An image processing method includes the following steps. An input data including a number of original data are received. The original data are converted into a number of converted emulation voltage signals. At least a simulation circuit model including at least a spatial data node, at least a diffusion node and at least a connection device is established, wherein, the at least a connection device is coupled to a part or all of the at least a spatial data node and the at least a diffusion node. A part or all of the converted emulation voltage signals are supplied to the diffusion node to achieve voltage diffusion among the spatial data nodes and the diffusion nodes via the connection device, so that at least a diffused emulation voltage signal is obtained on the diffusion nodes. Then, processed image data are generated according to the diffused emulation voltage signals.

Abstract: A method and apparatus in a data processing system for processing a request to display a pattern. A plurality of partitions is created in a memory in a graphics adapter in the data processing system, wherein each partition within the plurality of partitions has a size equal to each of the other partitions within the plurality partitions. A determination is made as to whether the pattern is present within the plurality of partitions. The pattern is displayed using the plurality of partitions if the pattern is present within the plurality of partitions. The pattern is retrieved from another location if the pattern is absent from the plurality of partitions. Responsive to retrieving the pattern from another location, the pattern is stored if the pattern is within the size.
