Abstract

Since embedded systems require ever more compute power, SMT processors are viable candidates for future high performance embedded processors. However, SMTs exhibit unpredictable performance due to uncontrolled interaction of threads. Hence, the SMT hardware needs to be adapted in order to meet (soft) real time constraints. We show by a simple policy that the OS can exercise control over the execution of a thread which is required for real time constraints.
