Abstract： The controller plays an important role in microwave landing system（MLS） navigation equipment. The embedded advanced reduced-instruction-set-computing（RISC） machine（ARM） is introduced to develop a new MLS controller based on the functional requirements. A design including hardware and software of an ARM system is given. The hardware design involves a ARM smallest system and its interface. μC/OS-II, a good real-time operating system (RTOS), is introduced in the software design. The task partitioning and management are also involved. The experimental results demonstrate that the embedded ARM technique is an effective way in the complex multi-task system, and it meets the high integration and real-time processing requirements of the navigation equipment.
Key words：microwave landing system (MLS); embedded reduced-instruction-set-computing（RISC）; advanced RISC machine（ARM）; real-time operating system（RTOS）; micro operating system (μC/OS)
