Abstract
A method is disclosed for controlling tearing in a display control system which includes first and second buffers, with input of data to a selected one of the buffers controlled by an input pointer and output of data from a selected one of the buffers controlled by an output pointer. Data is first input into the first buffer and substantially simultaneously data is output from the first buffer. The output pointer is then toggled such that data is input into the first buffer and output from the second buffer. Next, the input pointer is toggled, such that it is input into the second buffer and data is output from the second buffer. The output pointer is again toggled such that data is output from the first buffer and input into the second buffer.
