Research and design of high-speed dispatch-typesetting system based on USB2.0

This paper introduces the basic principles of laserdraw and dispatch-typesetting machines, analyzes the shortcomings of traditional dispatch-typesetting system, and proposed new design program based on the new dispatch-typesetting system based on USB2.0 and FPGA. At the same time, this paper discusses the hardware and software implementation techniques, and in-depth analysis on one of the key modules. While dispatch-typesetting system reduced costs dramatically, it is improving reliability, and it can meet the actual application requirements.
