Abstract: Smoother transitions between changing cursor images which are less stressful to the interactive user of a computer controlled display are provided by apparatus for changing the cursor image, including a frame buffer for storing the display screen image as a pixel array, a separate display buffer for storing the current cursor image as a pixel array, together with apparatus for storing an alternate cursor image as a pixel array during the display of the current cursor image, and means for replacing the current cursor image with the alternate cursor image. In raster scan apparatus for maintaining screen images in the frame buffer on said display screen, there are means for effecting the replacement of said cursor images during a vertical blanking period in said raster scanning.

Abstract: An aspect includes a system architecture that includes a processing unit, an accelerator, a main source buffer, a main target buffer, and a memory block. The main source buffer stores a first part of a source symbol received from an external source. The main target buffer stores an output symbol received from the accelerator. The memory block includes an overflow source buffer that stores the first part of the source symbol received from the main source buffer. The accelerator fetches the first part of the source symbol stored in the overflow source buffer and a second part of the source symbol stored in the main source buffer, and converts the first and second parts of the source symbol together into the output symbol. The second part of the source symbol includes a part of the source symbol not included in the first part of the source symbol.
