基于DSP和FPGA的笔划字符发生器设计

Design of Stroke Symbol Generator Based on DSP and FPGA

介绍了应用于航空电子系统中的一种笔划字符发生器设计方案;论述了该模块的功能要求以及硬件实现方法。该模块的设计基于高性能的数字信号处理器ADSP20160,通过软件产生各种满足要求的画面。该设计成功应用了可编程逻辑器件FPGA,简化了设计过程,缩短了设计周期,减小了模块体积并降低了设计成本。

This paper introduces a design scheme of an important module called stroke symbol generator （ SSG ） used in the aeronautical electronics system. It discusses the required functionality and describes the implementation methods in detail. The design of the module is based on a high performance DSP namely ADSP21060. The software generates all the satisfied graphics. In the design, we successfully use FPGA to simplify the process of design, shorten the design cycle, reduce the size of the module and the design cost.
