摘要： In a method of storing characters in a display system having a display device with an orthogonal matrix of addressable points, each character is represented as a succession of strokes each constrained to lie in one of the eight fundamental directions of the matrix and, except for the first stroke, each starting at the end of the previous stroke. Each such stroke is stored in a binary coded form which includes a first binary number (direction code) defining the angular direction of the stroke, a second binary number (length code) defining a number of matrix steps from one addressable point to the next along the stroke in that direction, and a third binary number (move/draw code) defining the visibility of the stroke. In order to facilitate character rotation by any multiple of 45.degree. the direction code defining each fundamental direction corresponds to the addition modulo 2.sup.n of a binary constant to the direction code which defines the fundamental direction of 45.degree. thereto in a given direction of rotation, where n is the number of bits in the direction code.

摘要： The specification describes a method of storing alphanumeric characters in a graphics display terminal comprising a raster-scan display device and a refresh buffer including a plurality of bit planes each having a respective bit storage location corresponding to each addressable pel position on the screen of the display device. In the method, a first bit plane stores high resolution luminance data defining alphanumeric characters each as a selection of "on" bits within a respective n.times.m array where n is the width of the character box in the scan line direction, and at least one further bit plane stores low resolution color data for the characters. The attribute plane comprises a respective n-bit set of storage locations which corresponds to each n-bit wide by one pel deep portion of a character box in the luminance plane and defines at least the color and/or intensity of the foreground and background of the character for the width of the character box in respect of a single scan line. The specification also describes a graphics display terminal in which data in the luminance and attribute planes may be selectively decoded either as alphanumeric data stored as above, or as bit-mapped graphics data.
摘要翻译：本说明书描述了一种在图形显示终端中存储字母数字字符的方法，包括光栅扫描显示装置和包括多个位平面的刷新缓冲器，每个位平面具有对应于显示器屏幕上的每个可寻址像素位置的相应位存储位置设备。在该方法中，第一位平面存储定义字母数字字符的高分辨率亮度数据，每个字符数字字符作为在相应的nxm阵列内的“开”位的选择，其中n是扫描线方向上的字符框的宽度，并且至少另外一个位平面存储字符的低分辨率颜色数据。属性平面包括对应于亮度平面中的字符箱的每个n位宽乘以一个像素深部分的相应的n位存储位置集，并且至少定义了前景和背景的颜色和/或强度相对于单个扫描线的字符框宽度的字符。本说明书还描述了一种图形显示终端，其中亮度和属性平面中的数据可以被选择性地解码为如上所述存储的字母数字数据，或者作为位映射图形数据。

摘要： A video signal is received from an asynchronous link (15) at an irregular frame rate for display on a computer monitor 9 at a regular frame rate. Frames are transferred to the monitor via first and second buffers (23, 25). A control process (27) manages the transfer of frames between the first and second buffers and is responsible for deciding if, when and how many frames to transfer, in order to minimise the delay between the incoming image and the displayed image.

摘要： A flexible dynamic memory controller that is operable with dynamic RAMS having a wide range of operating characteristics. These characteristics include different operating speeds for various memory functions, and the usage of memories. In a state machine, a special register is utilized to control where in the sequence of operation, and for how long various delays must be inserted. The delays are dynamically determined by the memory controller in accordance with the type of memory being accessed at a given time and the source of the request.
