摘要
介绍了页面描述语言(PDL)的概念及其在印字输出设备中的应用,讨论了页面描述语言的处理过程及其解释器的原理和实现方法,提出了基于数字信号处理器(DSP)的页面描述语言解释器及打印控制器的设计方法,并给出了其硬件框图和软件流程。试验结果表明,这种PDL解释器的性能较传统实现方法得到了大幅度的提高。
The concept of page description language and its applications in printers are introduced firstly. And DPL interpretation process, the theory and implementation method of its interpreter are discussed secondly. Finally, an interpreter/printer controller, which is based on a digital signal processor, is put forwarded. In addition, its hardware and software architecture and flowchart are presented. The test result shows that the performance of this PDL interpreter is greatly improved than that with convention implementation.
