基于FPGA的引信感应装定编解码器设计

Design of Codec on Inductive Fuze Setting System Based on FPGA

为了提高引信感应装定的可靠性和传输速率,采用FPGA设计了具有8位密码检测、5位群计数码检错和检错重接收功能的编解码器。该编码器可以嵌入到FPGA芯片系统资源共用同一个FPGA芯片,减少了设计电路体积,提高了系统的抗干扰能力。

For improving the reliability and transmission rate of inductive fuze setting system , based on FPGA a codec with the function of 8 bit passwords for identification was designed. The codec had five bits group counting codes for detecting errors and then was able to receiving new data if errors were detected. The codec could be completely embedded in FPGA chip system resources to share one FPGA chip,in that way the circuit board volume was reduced and the anti interference performance of the system was enhanced.
