A comparative study of redundancy in trace caches
Trace cache performance is limited by two types of redundancy: duplication and liveness. In this paper, we show that duplication is not strongly correlated to trace cache performance. Generally, the bestperforming trace caches also introduce the most duplication. The amount of dead traces is extremely high, ranging from 76% in the smallest trace cache to 35% in the largest trace cache studied. Furthermore, most of these dead traces are never used between storing them and replacing them from the trace cache.
