| Abstract(in English) | In recent years, memory protection for real-time systems is needed to ensure safety of the systerns. The MMU used for memory protection uses the TLB which is a caching mechanism. When using the TLB in real-time systems, the worst-case execution time (WCET)is estimated pessimistically, because it is difficult to predict the occurrence of the TLB misses. In this paper, first, we evaluate the impact of TLB misses on the WCET. Secondly, we propose methods to control the occurrence of TLB misses by using the TLB locking mechanism. The result of evaluation shows the effectiveness of the proposed methods. |
