摘　　要：多线程设计是现代软件设计的一个重点,在便携式频谱分析仪软件设计中有着更加严格的要求。本文针对便携式频谱分析仪高性能、低功耗指标需求,充分挖掘多线程程序设计的优点,提出了一种优化设计方案。该方案考虑"硬件优先,测量优先"的原则,权衡各线程在频谱分析仪软件中密切协作关系,从高效运行、节能、多线程协作与消除副作用4个方面进行了详细阐述。The multi-threading design is a point in modern software project, especially having more strict demand in portable spectrum analyzer software design. This text aiming at portable spectrum＇s high performance and low achievement consume target requirement, well scooping out the advantage of multi-threading program design, puts forward a kind of excellent project of design. The project considering the principle of ＂Hardware First, Measuring First＂, weighing close to cooperation relation of each threading in the spectrum analyzer software, sets forth its detailed design from the efficiently running, economizing on energy, multi- threading cooperation and cancellation side effect.
