| Abstract: | Based on having analyzed the working principle of the laser typersetter,this paper describes a design of the control interface between a computer and a laser typersetter.Some problems,such as the speed matches,the storage of graphical data, are discussed in detail.In the control process,the graphical data are stored in the high memory.To solve the speed difference between a computer and a laser typersetter,the multi buffering technique is used in the design.By using these methods,the whole graphical data can be delivered continuously.The basic ideal and implementing methods for data buffering,data delivering,data separating and data transforming are also discussed in this paper. |
