Abstract
As the existing techniques that empower the modern high-performance processors are being refined and as the underlying technology trade-offs change, new bottlenecks are exposed and new challenges are raised. This thesis introduces a new tool, Memory Dependence Prediction that can be useful in combating these bottlenecks and meeting the new challenges. Memory dependence prediction is a technique to guess whether a load or a store will experience a dependence. Memory dependence prediction exploits regularity in the memory dependence stream of ordinary programs, a phenomenon which is also identified in this thesis. To demonstrate the utility of memory dependence prediction this thesis also presents the following three novel microarchitectural techniques: 1. Dynamic Speculation/Synchronization of Memory Dependences: this thesis demonstrates that to exploit parallelism over larger regions of code waiting to determine the dependences a load has is not the best performing option. Higher performance is possible if memory dependence speculation is used especially if memory dependence prediction is used to guide this speculation.
