RTaW-ECU
RTaW-ECU is task scheduling configuration tool aimed at reducing the peaks of CPU load while meeting the timing constraints. RTaW-ECU constructs a static schedule of the tasks so that the workload is spread as uniformly as possible over time. This way it is possible to use less powerful CPUs and to execute additional tasks on the same hardware platform, another benefit is to offer a better resilience against wrong estimations of the task execution times or activation patterns.
Screenshot of RTaW-ECU: the graphic shows how the CPU workload is spread over time with different configuration algorithms. The bottom-right window shows the tasks scheduled during each time interval.
RTaW-ECU is able to construct the schedule for several hundred of periodic tasks (or runnables) in a few seconds and the quality of the resulting configuration can be visually checked and compared against simple strategies.
