摘　　要：针对TI高性能DSPTMS320C6414为核心处理器的实时数字图像压缩系统,进行了高速电路设计,分析了多层高速印刷电路板设计中影响信号完整性和实时压缩系统正常工作的相关问题。运用hyperlynx软件,解决了信号的反射、振铃和串扰等问题。并给出了设计印刷电路的具体参数,有效地抑制了实时数字图像压缩系统中的电磁干扰。the signal integrality and reliability are analyzed in high-speed multilayer PCB design of real-time digital image compression. In which high performance DSP TMS320C6414 of Texas Instruments was used to complete the digital image compression algorithm. The problems of signal integrality are described. The problems of line reflection, ringing, cross talk and electromagnetic interference were solved by using simulator Hyperlynx. The concrete measures were put forward to prevent and restrain the electro-magnetic interference in high-speed multilayer PCB design of real-time digital image compression.
