Abstract
This video graphics display system includes an apparatus that allows any portion of the complete image to be displayed independently. Focusing on a specific area of an image, or panning, results in a significant change in the relationship between the data stored in the video memory and the arrangement of the pixels on the monitor. This display system recalculates the timing and location of the multiple data transfers necessary to display any portion of the graphics data held in memory. The required data transfers are performed through a handshake between the SMT02 and the BSR03. This handshake allows data transfers to occur during the monitor blanking period and in spite of restrictions imposed by the video memory specifications.
