Abstract: The advent of high performance multi-core processors in desktop computers has opened the door for high performance, yet easy to maintain and upgrade, adaptive optics control systems. We describe the Durham Adaptive Optics Real-time Controller, and give details of performance, including latency and jitter, and maximum frame rates as well as scalability with adaptive optics system size. This system is to be used as a laboratory test bench in Durham with low and high order (up to 32×32 actuators) systems, and also on-sky as a control system for CANARY.
