The rePLay framework provides a mechanism upon which a variety of code optimizations can be deployed as an application executes. In this thesis, two optimizations are explored. First, the order in which instructions are fetched is optimized. Performance with an optimized schedule is shown to improve by 2.63%. The second optimization is to partition instructions for a clustered microarchitecture...

Broad phase collision detection is a vital task in most interactive simulations, but it remains computationally expensive and is frequently an impediment to efficient implementation of realtime graphics applications. To overcome this hurdle, we propose a novel microarchitecture for performing broad phase collision detection using Axis-Aligned Bounding Boxes (AABBs), which exploits the paralleli...

This paper presents and employs a methodology to analyze application performance with respect to microarchitecture design. As demonstrated by a case study of Sweep3D, this methodology systematically evaluates application performance improvements associated with enhancements to a baseline processor architecture and, as a result, identifies a microarchitecture, derived from the baseline architect...

To harvest increasing levels of ILP while maintaining a fast clock, clustered microarchitectures have been proposed. However, the fast clock enabled by clustering comes at the cost of multiple cycles to communicate values among clusters. A chief performance limiter of a clustered microarchitecture is inter-cluster communication between instructions. Specifically, inter-cluster communication bet...

Students traditionally learn microarchitecture by studying textual descriptions with diagrams but few analogies. Several popular textbooks on this topic introduce concepts such as pipelining and caching in the context of simple paper-only architectures. While this instructional style allows important concepts to be covered within a given class period, students have difficulty bridging the gap b...

In type 1 diabetes, diabetic bone disease (DBD) is characterized by decreased bone mineral density, a state of low bone turnover and an increased risk of fracture. Animal models of DBD demonstrate that acquired alterations in trabecular and cortical bone microarchitecture contribute to decreased bone strength in diabetes. With anti-collagenolytic and anti-inflammatory properties, tetracycline d...

Power is rapidly becoming one of the primary design constraints for modern processor design due to increased complexity and speed of the system. Cycle-accurate microarchitecture-level power simulators such as Wattch [1], SimplePower [2], and TE EST [3], have been developed and used extensively to validate power-efficient microarchitecture innovations, including clock gating [4], dynamically rec...

The microarchitecture of the trabecular bone is an highly informative feature for osteoporosis assessment. High resolution peripheral quantitative computed tomography permits its in-vivo observation at a resolution of 82 μm. In this paper we propose an approach that assesses bone microarchitecture based on texture features extracted from the trabecular bone. The method is based on three-dimensi...
