摘　　要：无人机载雷达的合成孔径二维成像技术、空时二维慢速目标检测技术等,需要的单位时间计算量大。信号处理机近些年的发展出现了基于多核DSP的处理板,C6678在八核全开时单位功耗达到的计算量是最大的。本文通过在信号处理板上应用SYS/BIOS操作系统,将信号处理任务、数据处理任务、中心控制任务等以多线程的形式运行在同一个信号处理板上,满足了目前无人机载荷对信号处理机提出的体积、重量、功耗新需求,适应了轻小型高密度计算环境的新需求。The synthetic aperture 2-dimensional imaging technology and spatial-time 2- dimensional slow target detection technology of UAV-borne radar requires large computing amount in unit. As development of signal processor in recent years,processing board based on multicore DSP appears,the computing amount of C6678 reaches maximum using unit power consumption while 8-core is fully on. The missions like signal processing,data processing and central control are running in multithreading form on the same signal processing board by applying SYS/BIOS operating system on the signal processing board,and this met new requirements for volume,weight and power consumption of signal processor currently presented by UAV-borne load,and new requirement for small light weight high density computing condition.
