Branch predictor (BP) is an essential component in modern processors since high BP
accuracy can improve performance and reduce energy by decreasing the number of …

This paper explores Speculative Precomputation, a technique that uses idle thread context
in a multithreaded architecture to improve performance of single-threaded applications. It …

Whole program paths (WPP) are a new approach to capturing and representing a program's
dynamic---actually executed---control flow. Unlike other path profiling techniques, which …

Dynamic branch predictors are popular because they can deliver accurate branch prediction
without changes to the instruction set architecture or pre existing binaries. However, to …

This paper presents the Alpha EV8 conditional branch predictor The Alpha EV8
microprocessor project, canceled in June 2001 in a late phase of development, envisioned …

Nearly all personal computer and workstation processors, and virtually all high-performance
embedded processor cores, now embody instruction level parallel (ILP) processing in the …

As modern microprocessors employ deeper pipelines and issue multiple instructions per
cycle, they are becoming increasingly dependent on accurate branch prediction. Because …

The importance of an accurate branch prediction mechanism has been well documented.
Since the introduction of gshare and the observation that aliasing in the PHT is a major …

Deeply pipelined, superscalar processors require accurate branch prediction to achieve
high performance. Two-level branch predictors have been shown to achieve high prediction …

In this paper, we introduce and analyze the Optimized GEometric History Length (O-GEHL)
branch Predictor that efficiently exploits very long global histories in the 100-200 bits range …
