为满足天文观测及激光通信等领域的1000单元级以下的自适应光学(AO)系统的高速实时处理的要求,提出一种单板上实现高速实时计算的通用化技术方案。采用多核CPU实时计算波前,结合高速图像采集卡,以满足系统高帧频的需求；计算机系统采用Xenomai实时操作系统及Linux操作系统，以满足AO 系统低延迟的需求；实现了在单台计算机上集成实时处理与监控的紧凑型处理系统。采用向量指令优化及多核并行运算，在6核的计算平台上获取了峰值每秒510亿次浮点运算的计算能力，102 GB/s的通信带宽。仿真结果表明可以对1145个驱动器，949个子孔径的系统进行2000 Hz的处理，处理延迟低于240 μs；通过修改参数后，应用于光通信的137单元AO系统中，校正后斯特列尔比为0.61。结果表明该处理方案能满足1145单元以下AO 系统2000 Hz实时处理的需要,并具有通用性。

In order to satisfy the requirement of high speed and real-time processing for 1000-unit class adaptive optics (AO) system in telescope and free space laser communication system, a generic high speed and real-time processing platform on one board is proposed. Multi-core center processing unit (CPU) is arranged for wave-front real-time computing, combined with high speed frame-grabber, to achieve the purpose of high frame-frequency. Xenomai real-time operation system combined with Linux operation system is used to satisfy the requirement of low latency. A compact real-time controller is assembled in one computer. Computing power of 51 giga floatingpoint operations per second (GFLOPS) and communication band-width of 102 GB/s are achieved in a computer with 6-core, via vector instruction optimization and processing in parallel with multi-core CPU. The emulation result shows that processing frequency can be up to 2000 Hz for 1145-unit AO system with 949 sub-apertures, and the delay is below 240 μs. This processor is introduced to AO system for laser communication via adjusting the parameters, and Strehl ratio of 0.61 is achieved after correction. This indicates the scheme can satisfy the requirement of high speed and low latency for AO system with actuators below 1145 unit, with the merit of general purpose.
