摘要： An apparatus for flicker reduction and increased writing speed into image memory in a CRT display having an interlaced scan with masking of low priority symbols. The apparatus expands or duplicates adjacent picture elements to provide redundant illumination for alternate fields, thereby providing at least two adjacent illuminated picture elements proximate to a masking image to reduce flickering during the writing of alternate fields. Writing into a single memory location commands illumination of a plurality of adjacent pixels, thereby reducing image memory writing time. The apparatus utilizes an image memory wherein video bit signals are written into only storage locations whose binary x coordinate has a predetermined first digit, and whose binary y coordinate has a predetermined first digit. Signals in storage locations whose addresses correspond to picture elements P.sub.I,J, P.sub.I-1,J, P.sub.I-1, .sub.J+1, and P.sub.I, J+1 are read from the image memory, and a Boolean OR sum signal is generated therefrom which is converted to an analog signal. The picture element P.sub.I,J is illuminated in response to an analog signal representing the Boolean OR sum signal 1.

摘要： A radar display system (10) according to the present invention generates textured radar display data by utilizing a direct memory access receiver (12) to receive radially scanned radar data, to convert the radially scanned radar data into range bin data sets, and to store the range bin data sets. A graphics renderer (18) stores the set of range bin data sets in a texture memory (20) as a plurality of rectangular textures, and bit maps the rectangular textures to a series of display triangles in a frame buffer (22). The graphics renderer (18) colors the display triangles in accordance with the rectangular textures by performing a bi-linear interpolation of the color and warps the display triangles in accordance with the size of a display (24).

摘要： A symbol generator useful for stroke based and raster display systems provides the ability of generating ellipses and elliptical arc segments. A look-up table provides cosine and sine values for incremental angles which are multiplied by major and minor axis scale factors for a selected ellipse. Global input parameters permit rotation of all arcs and vectors to generate orthogonal projections, thereby producing 2-D and 3-D symbology.

摘要： A method and apparatus for converting polar format radar video data into a horizontal raster format output to a TV monitor. Radar video data comprises radar video pixels each having an associated intensity value and a polar coordinate in a raster display. The TV monitor includes a display screen including a plurality of pixels wherein each pixel has a corresponding X,Y address. The apparatus and method of the invention comprises steps or apparatus for storing the radar video pixels, translating X,Y addresses into corresponding angular and radial coordinates, scanning the storage means using the translated X,Y address and interpolating a radar intensity value for the translated X,Y address. The radar video pixels are indexed by radial and angular coordinates. The scanning process includes accessing at least four radar video pixels surrounding the translated X,Y address. In the preferred embodiment of the invention, the scan conversion of the X,Y addresses is accomplished in a seven stage scan converter pipeline.

摘要： Dual processor accelerated graphics rendering is a method which allows for optimizing graphics performance using two processors and 3D hardware accelerators. This method allows for real time embedded systems to have multiple partitions to render to multiple windows with non-blocking graphics calls. One processor queues up graphics calls within a discrete time because they do not interface with the graphics accelerator hardware. The second processor supports the hardware accelerator with drivers operating in a single partition. This design abstracts the graphics calls from the native interface of the graphics hardware accelerator.
