ABSTRACT:
A display scaler of the present invention typically includes (a) a memory for sending data, (b) a first variable length buffer for receiving the data from the memory, (c) a first scaler for scaling the data in a first direction, (d) a buffer controller for controlling the first buffer, (e) a memory controller for controlling sending of the data from the memory to the first variable length buffer, and (f) a main display controller for sending control signals to the first scaler, the buffer controller, and the memory controller. The display scaler may further include (g) a second buffer for receiving the scaled data from the first scaler and (h) a second scaler for scaling the scaled data in a second direction. The present invention provides a method of generating a first image on a first display window and a second image on a second display window. The method may include the steps of: (a) sending first data corresponding to a portion of the first image; (b) storing the first data in a first storage; (c) sending second data corresponding to a portion of the second image; (d) storing the second data in a second storage; (e) scaling some of the first data vertically and horizontally; (f) transmitting the scaled first data for display; (g) scaling some of the second data vertically and horizontally; and (h) transmitting the scaled second data for display.
