摘　　要：提出一种针对航天嵌入式软件的系统级虚拟测试环境实现技术。通过该技术实现的系统级虚拟测试环境准确同步每个弹上处理器的运行时间,并模拟各处理器板之间的硬件接口,使基于多处理器的嵌入式软件测试摆脱了半实物环境的制约,提高了测试有效性,缩短了测试周期。该技术利用操作系统提供的进程间通讯机制,构造了可扩展的弹上软件系统级测试环境,并且在实现系统互连的前提下保证了虚拟环境执行的高效率。A system-level virtual testing environment implementation technology is proposed for space embedded software. The environment is implemented through this technology that synchronizes each embedded processor and simulates the hardware interface among processor chips. It makes that the embedded software testing based on multiprocessor is free from the constraints of the semi-physical simulation test environment.The test efficiency is improved and the test cycle is shortened. Based on this technology,extensible embedded software testing environment is established by use of IPC mechanism provided by operating system. It also guarantees the high efficiency of environment execution on the premise of system interconnection.
