评价高性能CRT图形显示器重要指标之一是画线速度和可寻址数.目前国外高档图形显示设备的画线速度可达每帧无闪烁地画200～400米长的线条,可寻址数大都设置为4096×4096象素,有的竟高达8192×8192象素,因此提高画线速度和可寻址数已成为显示设备研制中的关键技术问题之一.本文阐述了一种具有高画线速度和可寻址数的“恒时”矢量发生器.其主要技术指标如下.(1)方式:“恒时”模拟画线.(2)画线速度:12.5ns/ru(光栅单位).(3)可寻址数:4096×4096ru.
Evaluation of high-performance CRT graphics display is one of the important indicators of line speed and addressable number.At present, foreign high-grade graphic display device drawing speed of up to 200 ~ 400 meters per frame flicker-free drawing lines, addressable Mostly set to 4096 × 4096 pixels, and some as high as 8192 × 8192 pixels, so to improve the speed of line drawing and addressable has become the development of display devices, one of the key technical issues.This paper describes a high-draw Linear speed and addressable number of “constant time” vector generator. The main technical indicators are as follows. (1) mode: “constant time ” analog drawing line. (2) drawing line speed: 12.5ns / ru (Raster unit). (3) Addressable number: 4096 × 4096ru.
