摘要： An arrangement providing frame buffer memory for an output display by which single buffer and double buffered application programs may be run singly or simultaneously is described. An array of video random access memory sufficient to store data for at least two complete frames is configured in three different ways depending on the applications being run. When only programs designed to run on a single frame buffer are run, the memory is configured as a single frame buffer. When a single program designed to run on double frame buffers is run, the memory is configured as two visible frame buffers. When multiple programs designed to run on double frame buffers are run, the memory is configured into one visible and one invisible frame buffer. Additionally, apparatus for selecting data to be furnished to the display depending on whether the program operates as a single buffered program, a double buffered program, or a plurality of double buffered programs is provided.

摘要： An inexpensive, low power visual display device has m n-bit/pixel frame buffers that hold m sets of pixel data, where m>1, and an n-bit controller for switching among the m n-bit/pixel frame buffers at a selected rate during a display cycle. The controller outputs a composite stream of the m sets of pixel data. A display having a matrix of pixels is coupled to the controller to receive the composite stream. The pixels are turned on and off in response to the composite stream of pixel data. Individual pixels have a grayscale shade reflecting an average duration that the individual pixel is on. The visual display device produces m.times.(2.sup.n -1)+1 grayscale shades, including white. The multi-buffer display device can be optimized in a manner which reduces power consumption or increases the number of gray scale colors in comparison to prior art single frame buffer visual display devices. A method for operating visual display devices is also disclosed.

摘要： A visual display system for use in computers includes a frame buffer for holding visual information data in a particular format for ready input to a visual display device. The system also includes a compressed frame buffer for storing the visual information data in a compressed format which can be rapidly decompressed in real-time and used in the visual display device. The data is compressed by a microprocessor during idle times and decompressed by a decompression circuit on the fly. In some circumstances, the power consumed by compressing and then repeatedly handling the compressed data is less than the power used to repeatedly handle the full uncompressed data set. The visual display system analyzes the visual information data and determines whether compression would help save energy. In the event that the handling of compressed data saves energy, the visual display system will use the compressed data set until the information is changed or updated. In this manner, the visual display system reduces power consumption which helps improve battery life in portable computers. A method for operating a visual display system using this energy saving compression technique is also described.

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.

摘要： In a video editing apparatus, picture-representing data are stored in an area of a RAM, with a section of the data being selected to be transferred to form a display picture. When a command is supplied for cutting-out a region of the display picture, to replace the cut-out region with other data, the corresponding data region of the RAM area is stored in memory. If the user subsequently designates that the original data of the cut-out region are to be temporarily replaced in the display picture, the position of the cut-out region is calculated with respect to the data region that is currently being selected from the RAM area, the position with respect to the display picture is thereby obtained, and the cut-out data region is then read out of memory and inserted into the display picture at the obtained position.

摘要： A system for improving access time to video display data uses a shadow memory having fewer storage locations than a display memory. The shadow memory and the display memory share a set of addresses such that data written to the display memory, at an address shared by the shadow memory, is identically written to the shadow memory. Read requests directed to the display memory result in: (a) data returned from the shadow memory when access to a shared address is requested, and (b) data returned from the display memory when access to a non-shared address is requested.
