摘要： A fluorescent lamp driver circuit has regulator (SR); primary circuit of transformer (TF); electronic switches (TR2A and TR2B) and current sensing device (Rsense) connected successively in series across power supply (PSF). Controller (CTRL) is connected to create a feed back loop. The secondary circuit of transformer (TF) is coupled to fluorescent lamps (U10 and U11) via ballast capacitors (C1 and C2). Diode (D1) creates unidirectional current flow, so current sensing device (Rsense) indicates only energy input to lamps (U10 and U11). Capacitors (C1 and C2) are placed physically very close to their respective lamps, enabling good matching of currents through lamps (U10 and U11). Pulse width modulator (PM) with predetermined input is connected to regulator (SR) and, via delay circuit (TD) to controller (CTRL), thus permitting a larger dimming ratio, and further control of input power. Overvoltage detector (OVD) is connected to sense the voltage across inductor (L3) and transformer (TF) giving further control in the event of excess voltage.

摘要： Four independent displays 12 to 15 are driven by an array of Video RAMS 0,0 to 3,3 whose rows provide respective consecutive lines of the raster in cyclic sequence determined by means of a barrel shifter (20). All four displays can then use common data storage and operate using an appropriately sized pixel array e.g. 4 x 4, 8 x 8, for image handling and processing.

摘要： For generating and processing display images (possibly different ones on respective multiple display units) a pre-processor (12) supplies data and commands to a SIMD (single instruction multiple data) 8 x 8 array (13) of processing elements (procells) (14), each arranged to process 32 bit data words internally but to output only 8 bits at a time. The array (13) comunicates with a barrel shifter cache (18) via a 512 bit (64 x 8) wide data bus. The cache (18) communicates with pixel stores (VIM) via a 712 bit wide K-bus so that pixzones comprising 8 x 8 arrays of pixels can be caled up for processing in the array/cache arrangement (13, 18). A next-pixzone generator (20) determines the consecutive pixzones for processing on the basis of commands from a SIMD instruction unit IS which also controls the SIMD array (13) and cache (18). Methods of using the SIMD array to generate next-pixel addresses upon which the next-pixzone generator acts are also described.

摘要： Computer graphics requiring three dimensional representation needs very fine colour shading which is not possible with only 8 planes (bits) per pixel. In order to provide improved colour shading with acceptable resolution a video raster signal, with n (e.g. 8) planes per pixel and based on a resolution of x pixels per line and y lines, can be selectively processed (M1, M2, M3) to provide mn (e.g. 16 or 24) planes per macro-pixel where m is an integer greater than 1 and m = m1.m2 where m1 is the dimension in pixels of each macro-pixel along the scan lines and m is the dimension of each macro-pixel transverse to the scan lines (in terms of lines of the normal raster). In one arrangement the 16 planes normally used to drive 3 colour guns (red, green and blue) for an odd-even pixel pair are used for providing non-intersecting sets of 5 planes for each of the guns. In another arrangement the 8 planes for odd and even pixels (i.e. 16 planes available) are used for the red and green guns respectively in one scan line of each pair of scan lines and in the other scan line of the pair 8 of the 16 planes are used for the blue gun, each of the guns being operated for 50% of the pixel scanning time.

摘要翻译：为了产生和处理显示图像（在各个多显示单元上可能是不同的），预处理器（12）将数据和命令提供给处理元件（处理）的SIMD（单指令多数据）8×8阵列（13） 14），每一个都被设置为在内部处理32位数据字，但一次只输出8位。阵列（13）通过512位（64×8）宽的数据总线与桶式移位器高速缓存（18）通信。高速缓冲存储器（18）经由712位宽的K总线与像素存储器（VIM）通信，使得包括8×8像素阵列的像素区可以在阵列/高速缓存设备（13,18）中被处理。下一个像素区域生成器（20）基于来自也控制SIMD阵列（13）和高速缓存（18）的SIMD指令单元IS的命令来确定用于处理的连续像素。还描述了使用SIMD阵列来生成下一像素区发生器在其上起作用的下一像素地址的方法。
