【摘要】 主机系统是新一代地震仪器的工作和调度核心。研究并设计了基于线程级并行处理模型的地震仪器主机软件系统体系结构。首先,建立任务模型,对主机软件系统进行任务划分;其次,利用线程管理、任务管理和实时调度,有效地利用硬件多核体系结构,以提高性能。模拟带道能力测试结果表明,在该软件体系结构下实现的主机软件系统带道能力满足1 ms@9 000道要求。更多还原

【Abstract】 Central recording system (CRS) is the fundamental part of the new generation seismographs.The software architecture of CRS,which is based on thread level parallelism,is studied and designed.Firstly,the task model is established and CRS is broken down to different tasks.Secondly,the thread management,task management,and real-time scheduling are implemented to take full advantage of multi-core architecture.Simulated experiments show that CRS implementation meets the requirement of the channel capacity:1ms@9000 channels.更多还原
