摘要

介绍了一个基于FPGA（现场可编程门阵列）技术的医学图象打印系统，它利用热敏打印方式，采用分层打印的方法，用高性能的薄膜热印头打印出层次丰富的灰度图象。该系统的采样控制和数据处理逻辑集成在一块FPGA芯片上。同以往使用通用器件实现的控制电路相比，器件速度快、设计的灵活性大、可靠性高，性能良好。

Abstract

This paper presents a Video Print System based on FPGA. Using the print method of apart-layers

we have accomplished Full-Tone Rendition print with high-performance thermal heads. The Acquisition and Processing Logic(APL) was implemented using a FPGA device. Compared with a previously design using 7 400-series and 4 000-series chips

this one has better characteristics. The devices operate fast and the system provides high-performance. FPGA technology improves flexibility and reliability of the design.
