即将到来的超大型望远镜(ELT)都需要自适应光学系统才能成功运行。这些系统的实时控制在计算上变得具有挑战性，部分受到波前重建所需的存储器带宽的限制。研究了POWER8处理器新技术在自适应光学实时控制中的应用。这些处理器具有很大的存储带宽，我们证明了它们适合于第一光ELT仪器的操作，并提出了一些潜在的实时控制系统设计。基于中央处理器(CPU)的实时控制系统显著降低了复杂性，提高了可维护性，并增加了实时控制系统的寿命。
The forthcoming Extremely Large Telescopes (ELTs) all require adaptive optics systems for their successful operation. The real-time control for these systems becomes computationally challenging, in part limited by the memory bandwidths required for wavefront reconstruction. We investigate new POWER8 processor technologies applied to the problem of real-time control for adaptive optics. These processors have a large memory bandwidth, and we show that they are suitable for operation of first-light ELT instrumentation, and propose some potential real-time control system designs. A central processing unit (CPU)-based real-time control system significantly reduces complexity, improves maintainability, and leads to increased longevity for the real-time control system.
