STUDIES OF PERFORMANCE AND PREDICTABILITY OF CACHE-LOCKING

Today’s real-time systems need to be faster and more powerful than ever before. Caches are an architectural feature that helps solve this problem. Caches however are unpredictable and do not improve the worst case execution time. This work studies the effects of cache-locking on performance and time predictability. Two locking methods were evaluated: a dynamic locking method and a static locking method. The performance of single and multi-core processors and multiple levels of caches were studied. The time predictability of the single core system was studied and the cost of the time predictability was determined for each locking method. Cache-locking in the Level 2 cache had the best performance and the static-locking method had the highest predictability.
