 DESCRIPTION:
-    When defined, the Simple Priority Scheduler is used at the thread
-    scheduling algorithm. This is an alternative scheduler in RTEMS.  It is
-    designed to provide the same task scheduling behaviour as the Deterministic
-    Priority Scheduler while being simpler in implementation and uses less
-    memory for data management.  It maintains a single sorted list of all ready
-    threads.  Thus blocking or unblocking a thread is not a constant time

+    in RTEMS for uni-processor applications. The CBS is a budget aware
+    extension of EDF scheduler. The goal of this scheduler is to ensure
+    temporal isolation of tasks. The CBS is equipped with a set of additional
+    rules and provides with an extensive API.
 
     This scheduler may be explicitly selected by defining
