ABSTRACT:
A video controller and related method for controlling a manner in which input data is printed is provided. Specifically, the controller contains a first AND gate, a buffer, a second AND gate, a third AND gate, and a bus holder. The first AND gate inputs the input data and a chopping control signal and outputs a corresponding chopping output signal. The buffer inputs delayed input data and a buffer control signal. The delayed input data corresponds to the input data which has been delayed for a predetermined period of time, and the buffer outputs the delayed input data as a shrinking control signal in accordance with the buffer control signal. The second AND gate inputs the shrinking control signal and the input data and outputs a corresponding shrinking output signal. The third AND gate inputs the chopping output signal and the shrinking output signal and outputs corresponding output data. Finally, the bus holder maintains an output state of the buffer at an appropriate level.
