    摘要： A central processing unit (CPU) is provided and is coupled to a display for displaying graphic and other data in multiple overlapping windows. The CPU is further coupled to one or more input devices which permits a user to selectively position a cursor and input and manipulate data within each of the windows on the display. The windows include defined areas having window features such as text, icons and buttons corresponding to functions to be executed by the CPU. Multiple applications may be executed concurrently by the CPU such that each application is associated with one or more windows. Each display element ("pixel") comprising the display is represented by multiple bits in a computer frame buffer memory coupled to the CPU. An alpha value (.alpha.) is associated with the intensity of each pixel of the display, such that multiple images may be blended in accordance with a predefined formula utilizing the alpha values. By setting the alpha values appropriately, transparency may be accomplished such that data associated with underlying windows may be rendered visible to the user. Effectively, the present invention merges multiple images through alpha "blending" such that several images appear transparently on top of one another. The present invention, through the selective use of alpha blending, permits underlying windows to display data visible to the user through windows which are overlaid above an underlying window.

    摘要： A method and apparatus for quickly copying a first frame region into a second frame region. A video memory array comprising a plurality of video random access memory devices is divided into at least two frame regions. A background image is rendered by a central processing unit into a background frame region within the video memory array. The central processing unit then requests the background image in the background frame region to be copied into a new frame region in the video memory array. A dedicated circuit copies the entire background image in the background frame region into the new frame region. The dedicated circuit operates by using a serial data register within each video random access memory device during the vertical retrace period of a video timing signal. The dedicated circuit performs the background frame copy without requiring any processing resources from the central processing unit.
