CANARY是一个多目标自适应光学（MOAO）系统，旨在演示拟议的EELT仪器，如多目标摄谱仪EAGLE的AO方面。金丝雀的第一阶段将于2010年在4.2米的威廉赫歇尔望远镜上执行。我们在这里描述的AO实时控制系统（RTCS）金丝雀。这是基于通过快速串行结构（sFPDP）互连的组件的分布式架构。所使用的硬件是FPGA和CPU技术的混合。系统数据测控中间件是基于CORBA和发布/订阅模式的。该系统的设计是很容易修改和扩展的后期，高阶，阶段的加那利群岛。为了提供高阶系统中所需的计算能力的增加，当前的CPU技术可以容易地被基于FPGA或GPU技术的加速硬件所取代。因此，Canary RTCS为E-ELT仪器所需的这些新技术提供了一个测试平台。这些设计概念可用于为E-ELT仪器提供RTCS，并与ESO正在考虑的E-ELT AO系统（EAGLE等仪器需要与之连接）的设计概念一致。
CANARY is a Multi-Object Adaptive Optics (MOAO) system designed to demonstrate the AO aspects of proposed EELT instruments such as the multi-object spectrograph EAGLE. The first phase of Canary will be executed on the 4.2m William Herschel Telescope in 2010. We describe here the AO Real-time Control System (RTCS) for Canary. This is based on a distributed architecture of components interconnected by a fast serial fabric (sFPDP). The hardware used is a hybrid of FPGA and CPU technology. The middleware used for system data telemetry and control is based on CORBA and the publish/subscribe pattern. The system is designed to be easily modified and extended for the later, higher order, phases of CANARY. In order to provide the increase in computational power required in higher order systems, the current CPU technology can be readily replaced by acceleration hardware based on FPGA or GPU technologies. The Canary RTCS thus provides a test-bed for these new technologies that will be required for E-ELT instruments. These design concepts can be developed to provide an RTCS for E-ELT instruments and are in line with those under consideration by ESO for the E-ELT AO systems to which instruments such as EAGLE will be required to interface.
