The Thirty Meter Telescope (TMT) will be used with Adaptive Optics (AO) systems to allow near diffraction-limited performance in the near-infrared and achieve the main TMT science goals. Adaptive optics systems reduce the effect of the atmospheric distortions by dynamically measuring the distortions with wavefront sensors, performing wavefront reconstruction with a Real Time Controller (RTC), and then compensating for the distortions with wavefront correctors. The requirements for the RTC subsystem of the TMT first light AO system will represent a significant advance over the current generation of astronomical AO control systems. Memory and processing requirements would be at least 2 orders of magnitude greater than the currently most powerful AO systems using conventional approaches, so that innovative wavefront reconstruction algorithms and new hardware approaches will be required. In this paper, we will first present the requirements and challenges for the RTC of the first light AO system, together with the algorithms that have been developed to reduce the memory and processing requirements, and then two possible hardware architectures based on Field Programmable Gate Array (FPGA).

The Thirty Meter Telescope (TMT) will be a ground-based, 30-m optical-IR telescope with a highly segmented primary mirror located on the summit of Mauna Kea in Hawaii. The TMT Observatory Software (OSW) system will deliver the software applications and infrastructure necessary to integrate all TMT software into a single system and implement a minimal end-to-end science operations system. At the telescope, OSW is focused on the task of integrating and efficiently controlling and coordinating the telescope, adaptive optics, science instruments, and their subsystems during observation execution. From the software architecture viewpoint, the software system is viewed as a set of software components distributed across many machines that are integrated using a shared software base and a set of services that provide communications and other needed functionality. This paper describes the current state of the TMT Observatory Software focusing on its unique requirements, architecture, and the use of middleware technologies and solutions that enable the OSW design.
