RTaW-ECU : static cyclic scheduling of tasks
RTaW-ECU is task scheduling configuration tool for monocore and multicore platforms which is aimed at reducing the peaks of CPU load while meeting the configuration and timing constraints
Key Benefits
RTaW-ECU constructs the 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.
RTaW-ECU is able to construct the schedule for several hundred of software modules in a few seconds and the quality of the resulting configuration can be visually checked and compared against simple strategies.
RTaW-ECU is free for all uses
