Appl. No.:

8/161705

Inventors:

Karl M. Guttag - Houston TX
Michael D. Asal - Sugarland TX
Mark F. Novak - Colorado Springs CO

Assignee:

Texas Instruments Incorporated - Dallas TX

International Classification:

G06F 1562

US Classification:

395157

Abstract:

The present invention is a graphics data processor which includes the capability of determining whether a defined pixel location in a graphics display is within a window in an X Y coordinate system. The respective X and Y coordinates of the selected pixel are separately compared with the window limits. The window limits are preferable expressed as the X and Y coordinates of two diagonally opposite vertexes of a rectangular window. The results of this comparison are preferable available in two forms. In a first embodiment a single data processing instruction enables the generation of a digital data word which indicates the relation of the pixel to the window. This digital word includes a separate indication of the relationship of the pixel to the vertical and horizontal window limits. This indication can be used to generate a "trivial rejection" in determining whether a line or line segment passes through the window by ANDing the results for two points on the line. In a second embodiment the window compare capability is employed to determine whether or not a destination pixel is within the window.

US Classification:

364521

Abstract:

The graphics data processing apparatus which can logically combine the color data for two image arrays on a pixel by pixel basis, according to a nonlinear saturating function. Two examples of such functions are addition with saturation at the maximum value and subtraction with saturation at the minimum value. These functions can be employed to obtain computer graphics effects not feasible using other function, such as simulating spray painting and light mixing.

International Classification:

G11C 800

US Classification:

365219

Abstract:

In a video-type computer system and the like, an improved memory circuit is provided for adapting the system to CRT screens having different resolutions. The memory circuit includes a bit-mapped RAM unit or chip having sufficient cells to accommodate any CRT screen sought to be used, and also a shift register having taps at a plurality of different locations corresponding to different columns of cells in the RAM unit. When the RAM unit is in serial mode, column address to the RAM unit is also used to instruct and actuate a suitable decoder circuit to select the tap appropriate to unload the portion of the shift register containing only the data bits of interest.

Abstract:

In a computer system, an improved memory circuit is provided for accomodating video display circuits with CRT screens having different resolutions. The memory circuit includes a bit-mapped RAM unit or chip having sufficient cells to accomodate any CRT screen intended to be used, and it further includes a serial shift register having a plurality of taps at locations corresponding to different preselected columns of cells in the chip. In the system, provision is included for selecting taps to unload only the portion of the shift register containing the bits of interest, whereby unused portions of the chip may be effectively excluded and the time for transferring data of interest to the CRT screen is reduced.

International Classification:

G06F 1206

US Classification:

345517

Abstract:

The graphics data processor of the present invention offers as a single instruction in its instruction set a draw and advance operation. A first data register stores a set of X and Y coordinates. In a first embodiment, a predetermined color code is stored at the pixel address of a bit mapped display memory indicated by the X and Y coordinates the first data register upon execution of the the draw and advance instruction. The X and Y coordinates stored in the first data register are then advanced by addition of X and Y coordinates stored in a second data register. A second embodiment is similar except that the color code stored at the X and Y coordinates of the first date register is recalled for combining with the predetermined color code and the combined result stored at that pixel location. The predetermined color code is preferrably stored in another data register. By proper selection of the X and Y coordinate data stored in the second data register either the X or the Y coordinate may be altered alone or both may by simultaneously changed.

Abstract:

A video memory controller controls a DRAM (dynamic random access memory) used as a video memory and as a system memory. The video memory and the video memory controller are normally a part of a video system which includes a data processor, the video memory, the video memory controller, a CRT controller and a CRT display device. The video memory controller includes a row address latch for storing a row address from the data processor, a column address latch for storing a column address from the data processor, a refresh address register for storing a memory refresh address and a display update generator for sequentially generating the addresses necessary for update of the CRT display. A multiplexer couples the proper address to the video memory under control of a memory cycle generator which generates the timing of the memory refresh and display update. An arbiter device enables only one of the possible memory cycles at a time.
