Cycle-Resolution Timing is an advanced scheduling technique used in SEGGER’s RTOS embOS-Ultra that offers significant benefits in terms of precision, efficiency, and power consumption. This article shows how Cycle-Resolution Timing works, how it compares to RTOSs using traditional methods, and the advantages it offers for embedded-system development. Know your embedded-system architecture Before diving into the specifics of Cycle-Resolution Timing, it is important to understand how traditional RTOSs work. Bare-metal and super-loop architecture: In many simple embedded systems, developers use a bare-metal and/or super-loop architecture, where a system continuously runs a in a loop, checking for events and executing tasks. This approach is simple, but it has limitations: Task management is carried out manually, which can quickly become complex as the system grows. Power consumption is high because the system runs continuously, even when no tasks are scheduled. Debugging and
