摘　　要：针对空间站传统有效载荷功能单一、处理资源固化、体系架构封闭等问题,通过对空间站电子信息综合应用系统总体功能和资源需求的分析,基于空间站平台约束条件,设计了一种在开放式物理平台上采用蓝图技术实现软件定义功能的综合处理单元(IPU),并对一套对外接口传输能力为600Gbps、处理能力为1800GFLOPS的原理样机进行了测试验证。结果表明,IPU支持在统一平台上通过软件定义功能,能有效提升系统资源利用率,满足总体应用需求。The traditional payloads of the space station have many problems such as single functionality, solidified processing resources and closed architecture. The overall functions and resource requirements of the integrated application system of the space station were analyzed and an open physical platform was designed based on the constraints of the space station platform. The blueprint technology was used to realize the integrated processing unit(IPU) of software-defined functions. A prototype with 600 Gbps external transmission capability of and 1800 GFLOPS processing capability was tested and verified. The test results showed that the IPU could support the software-defined functions on a unified platform. It could effectively improve the system resource utilization and meet the overall application requirements.
