摘　　要：结合继电保护测试装置的研制体会,介绍了基于DSP的CPLD多方案现场可编程配置方法,给出了硬件的配置连接、CPLD配置数据的获取与存储方法,同时给出了CPLD在DSP控制下的被动串行配置过程。本设计方法无需专用配置PROM,而是由DSP提供配置方案给CPLD来实现同一硬件对不同类型信号的检测与控制。Withthe developingexperience in the relay-safeguard testdevice,this paper offers the design of mulˉti-project in-system programable configuration of CPLD based on DSP.The paper also presents the hardware connection,the gain and storage measure of configuration data of CPLD and the PS configuration process moniˉtored by DSP.In the design,each project of configuration is provided to CPLD by DSP,no the special PROM,to realize the aim that one hardware examines and controls different style of signal.

关 键 词：DSP CPLD 被动串行配置 MCBSP
