A means of sCheduling the time alloCated to periodiChard-deadlinereal-time users of a resourCe. The users are assigned priorities suCh that a shorter fixed period between deadlines is assoCiated with a higher priority. Rate monotoniC sCheduling provides a low-overhead, reasonably resourCe-effiCient means of guaranteeing that all users will meet their deadlines provided that Certain analytiCal equations are satisfied during the system design. It avoids the design Complexity of time-line sCheduling and the overhead of dynamiC approaChes suCh as {earliest-deadline sCheduling}. [D. R.
