    摘要: In an image displaying field where there is a tendency which will increase the data to be handled in accordance with the high integration of a display device, a CRT controller according to the present invention improves the superposed display and the responsiveness of the display and drawing operations by dividing a unit clock into a predetermined number to function with high speed and a multifunctional display. When image data are to be inputted or outputted from a refresh memory corresponding to a display frame, the memory content and the display address are assigned at a ratio of 1:n to effect the processings in parallel. As a result, the time period utilized by the display cycle of the prior art can be assigned to the drawing operation so that the processing can be speeded up while making it easier than the prior art to effect the superposed display of letters, symbols and drawings. The resultant effect is that it is unnecessary to increase the number of refresh memories corresponding to the displayed frame and that the external parts can be simplified to contribute to the improvement in the reliability.

The system further includes circuitry (24,34,36) coupled to an output of the image buffer for converting image pixel data read therefrom to electrical signals for driving an image display (18). The circuitry is responsive to signals generated by an image display controller (16) for generating one of a plurality of different timing formats for the electrical signals for driving an image display having a specified display resolution. The apparatus further includes circuitry (40,42) for configuring the image buffer in accordance with the specified display resolution. The image buffer is configurable, by example, as two, 2048 location by 1024 location by 24-bit buffers and one 2048 location by 1024 location by 16-bit buffer; or as two, 2048 location by 2048 location by 24-bit buffers and one 2048 location by 2048 location by 16-bit buffer. Each of the 24-bit buffers store R,G,B pixel data and the 16-bit buffers each store a color index (CI) value and an associated window identifier (WID) value. Circuitry at the output of the image buffer decodes CI and WID values into R,G,B pixel data and a Key value specifying pixel mixing.

    摘要: A computer system is provided which employs a hardware rotation unit capable of rotating a raster-scan portrait image by 90 degrees in a clockwise or counter-clockwise direction in order to create a landscape image on a raster-scan display device. Rotation of a portrait image is accomplished by a mapping of pixel information associated with the portrait image to corresponding frame buffer locations necessary to properly display the portrait image as a landscape image. A video controller incorporating the hardware rotation unit stores only pixel information associated with the landscape image in a frame buffer. Dedicated circuitry within the hardware rotation unit allows full support of portrait image data read and write operations involving the landscape image pixel information stored in the frame buffer.

    摘要: A single-chip video-graphics controller includes a novel circuit for eliminating full line buffers when reducing line-to-line flicker in a display image of non-interlaced data on an interlaced color display device such as an NTSC or PAL television projector. The flicker reduction circuit uses a pair of memory access agents for concurrently fetching even and odd interlace frames of the display image. Corresponding color pixels of the two frames are averaged on-the-fly, and the averaged output is converted to analog RGB output signals for driving the display device. The elimination of the full line buffers results in a savings of approximately 30,000 transistors per buffer and a corresponding reduction in operating power. A specific embodiment of the controller includes a vertical stretching circuit used to adjust the number of vertical lines corresponding to the display image permitting the vertical reformatting of any display image.
