Datacenter applications are well-known for their large code footprints. This has caused
frontend design to evolve by implementing decoupled fetching and large prediction …

Conventionally, branch mispredictions are resolved by flushing wrongly speculated
instructions from the reorder buffer and refetching instructions along the correct path …

Advancements in branch predictors have allowed modern processors to aggressively
speculate and gain significant performance with every generation of increasing out-of-order …

Despite very accurate branch predictors, branch misses remain an important source of
performance limiters, especially for irregular applications. To ensure in-order commit, branch …

Modern processors include reservation stations to host instructions that are waiting to be
sent to the execution units. Responsive to exception event, instructions in reservation …
