基于SOPC技术的地球物理模拟可控震源研制

Design of Controlled Geophysical Model Signal Generator Based on SOPC

选用基于SOPC内核的专用芯片设计了地震物理模拟可控震源硬件平台;设计中,编写了基于Avalon总线接口与寄存器接口文件,应用SOPC Builder完成D/A模块的IP核设计以及系统外设IP核的配置工作,完成了可控震源硬件平台间各个功能模块的逻辑与时序接口控制;从实际测试结果来看,达到了设计的预期目的;该方案的优点在于通过SOPC技术来完成软硬件设计,系统集成度高,硬件平台可移植性好;经过实际应用,满足工程实际需要。

Based on the research of SOPC architecture,A SOPC chip is exploited to produce a controlled geophysical model Signal Generator.In the paper interface timing logics about the system is designed on SOPC kernel.Application of system IP and IP core self-completed by SOPC Builder accomplished the design about high speed D/A and the extension of system external instruments.From the test result in practice,it proves the design have achieved the expected objectives.The advantage of the design lies in simplicity and high integration.
