Understanding Prediction Limits Through Unbiased Branches
The majority of currently available branch predictors base their prediction accuracy on the previous k branch outcomes. Such predictors sustain high prediction accuracy but they do...

Using Branch Prediction Information for Near-Optimal I-Cache Leakage
This paper describes a new on-demand wakeup prediction policy for instruction cache leakage control that achieves better leakage savings than prior policies, and avoids the perform...

Functional Unit Chaining: A Runtime Adaptive Architecture for Reducing Bypass Delays
Abstract. Bypass delays are expected to grow beyond 1ns as technology scales. These delays necessitate pipelining of bypass paths at processor frequencies above 1GHz and thus affe...

Reorganizing UNIX for Reliability
In this paper, we discuss the architecture of a modular UNIX-compatible operating system, MINIX 3, that provides reliability beyond that of most other systems. With nearly the ent...
