基于DSP FPGA的弹载计算机设计

Design of Missile-borne Computer Based on DSP+FPGA

摘要:

针对现代弹载计算机硬件系统的发展趋势,结合某型反坦克导弹的实际应用需求,采用以DSP作为处理器实现控制系统的核心算法,以FPGA实现外围接口扩展的方案,设计出了一套基于DSP+FPGA的微小型导弹载计算机。文章对该弹载飞控计算机的结构、硬件、软件等方面内容作了详细的介绍,并给出了软件流程图、介绍了软件各模块的详细功能。本文设计的弹载计算机体积小,功率低,其性能已在实验中得到了验证,这为未来弹载计算机的设计提供了参考。

Abstract:

With the development of modern missile-borne computer hardware system, the actual application of a certain type of anti-tank missiles is taken into consideration. Thus, we design a micro and small missile-borne computer system based on a DSP processor as the core algorithm of the control system and a FPGA to implement peripheral interface expansion program. This paper researches the missile-borne flight control computer architecture, hardware, software, and other aspect in detail, and gives the software flow chart, describes the detailed features of the software for each module. The missile-borne computer designed this article is with small size and low power. Moreover, its performance has been verified in experiments, which provides a reference for the design of future missile-borne computer.
