摘　　要：针对水中目标探测平台低功耗和实时性的需求,提出了一种基于HPI接口的双CPU目标探测平台设计方案,并给出了硬件实现。首次将并行的HPI接口应用到水中目标探测平台上,有效地提高了数据交换速度;采用"Sleep/Wake"工作体制进行软件编程,降低了系统功耗。消声水池实验运行结果表明,该平台设计可行,各功能模块均正常工作,系统平均功耗在18 mW左右,达到了预期的设计指标。The low-power consumption and real-time demand of the underwater target detection platform is focused on. A du- aL-CPU target detection hardware platform based on host port interface which is called HPI for short is designed. The paralLeL HPI connection pattern is applied for the first time on the underwater target detection platform. In this way, the data exchange speed is raised effectively. In the aspect of the software programming, a ＂sleep and wake＇work system is employed to reduce the system power consumption. The experimental results in the anechoic water tank show that the design of the hardware platform is feasible, each functional module works normally, and the average power consumption is about 18 mW. So the platform satisfies the different requests of target detection system.
