Abstract�� In order to reserve the valuable software and hardware fruits of the Cyber data acquisition system,the method of software simulation was adopted to build a simulation system on a modern high performance hardware platform��Petroleum industry’s Cyber data acquisition simulation system was modeled by taking individual real devices as fundamental items and it shaped an architecture which contained a instruction-set simulator as a core,a communication bus simulation module as a bridge that connected each device simulation module��In order to meet the deadline of simulation system,its real-time performance was analyzed at length according to the average performance requirement and the worst performance requirement,and serveral performance parameters were extracted,then a real-time solution which based on a real-time operating system RTLinux was provided to solve the real-time communication problem between the simulation system and the real data acquisition devices��
Keywords�� instruction-set simulator   deadline   RTLinux   real-time operating systems
