Exploiting selective instruction reuse and value prediction in a superscalar architecture
2009
In our previously published research we discovered some very difficult to predict branches, called unbiased branches. Since the overall performance of modern processors is seriously affected by misprediction recovery, especially these difficult branches represent a source of important performance penalties. Our statistics show that about 28% of branches are dependent on critical Load instructions. Moreover, 5.61% of branches are unbiased and depend on critical Loads, too. In the same way, about 21% of branches depend on MUL/DIV instructions whereas 3.76% are unbiased and depend on MUL/DIV instructions. These dependences involve high-penalty mispredictions becoming serious performance obstac…
Unbiased Branches: An Open Problem
2007
The majority of currently available dynamic branch predictors base their prediction accuracy on the previous k branch outcomes. Such predictors sustain high prediction accuracy but they do not consider the impact of unbiased branches, which are difficult-to-predict. In this paper, we evaluate the impact of unbiased branches in terms of prediction accuracy on a range of branch difference predictors using prediction by partial matching, multiple Markov prediction and neural-based prediction. Since our focus is on the impact that unbiased branches have on processor performance, timing issues and hardware costs are out of scope of this investigation. Our simulation results, with the SPEC2000 in…
Developments and trends in learning with instructional video
2018
" This special issue provides an overview of some of the main topics addressed in contemporary research on learning with instructional video. The aim of the contributing papers is to take the field of learning with instructional video a step further so as to better understand the circumstances under which instructional videos do and do not improve learning and how instructional videos can be more optimally designed to support learning."
