Abstract:

A system and method for processing analog XYZ calligraphic video signals for presentation as a stroke image on a flat panel LCD raster display screen by converting such signals in coordinated sets to digital data in a stroke frame buffer memory. The X and Y signals define column and row addresses in memory for storage of the coordinated Z digital color brightness data, which addresses correspond to pixel locations on the surface of the display screen to which the data is transferred to form the stroke image. By storing fractional bits from the X and Y digital data in the buffer memory along with the coordinated color intensity data a high resolution stroke image can be formed using a conventional sized buffer memory. Further, noise and clock conversion artifacts are minimized by saving the first point of each stroke line or vector and by using the X and Y fractional bits for beam shaping utilizing anti-aliasing discs. The discs are a set of prestored circular intensity profiles, each covering several pixels and having their respective centers variously offset by fractions of a pixel spacing from points defining the ideal center of the stroke line to be formed.

Abstract:

Systems and methods for regulating communications in computing systems are provided. For instance, a computing system can include a first processing board including a first processing device and a first control device. The system can further include a second processing board including a second processing device and a second control device. The system can further include a communications interface communicatively coupled to the first processing board. The communications interface includes one or more input/output ports configured to facilitate communication between the avionics system and one or more external devices. The first control device of the first processing board is communicatively coupled to the second control device of the second processing board via a shared bus. The first control device is configured to regulate communications associated with the communications interface.
