After having presented web-based Calculus courses for a number of years, we investigate the impact that this medium of instruction has on the student’s mathematical and general academic progress. Since our web-based model is much more flexible than the conventional contact lecture model, we surmised that this may contribute to the student becoming more of an independent learner than does the co...

For the last two decades, computers have entered people’s lives in an unprecedented manner in a way that almost everybody considers life without them rather impossible. In recent years, researchers and educators have been trying to discover how computers and the Internet technology can maximize the quality of language instruction. As such, the present experimental study sought to investigate th...

Modern processors use Branch Target Buffers (BTB) to predict the target address of branches so that they can fetch ahead in the instruction stream increasing concurrency and performance. Ideally, BTBs would be large enough to capture the entire working set of the application and small enough for fast access and practical on-chip dedicated storage. Depending on the application, these requirement...

Trade-o s between code selection, register allocation, and instruction scheduling are inherently interdependent, especially when compiling for ne-grain parallel architectures. However, the conventional approach to compiling for such machines arbitrarily separates these phases so that decisions made during any one phase place unnecessary constraints on the remaining phases. Mutation Scheduling a...

Register allocation and instruction scheduling are antagonistic optimizations: Whichever is applied rst, it will impede the other. To solve this problem, we propose dependence-conscious colouring, a register allocation method that takes the dependence graph used by the instruction schedu-ler into consideration. Dependence-conscious colouring consists of two parts: First, the interference graph ...

This paper discusses the potential of applying computer-animated instruction (CAnI) as an effective conceptual change strategy in teaching electrochemistry in comparison to conventional lecture-based instruction (CLI). The core assumption in this study is that conceptual change in learners is an active, constructive process that is enhanced by the pedagogic use of computer-animated images. The ...

The trend of deep pipelining and multiple instruction issue has made instruction sequencing an extremely critical issue. This paper de nes Inline Target Insertion, a speci c compiler and pipeline implementation method for Delayed Branches with Squashing. The method is shown to o er two important features not discovered in previous studies. First, branches inserted into branch slots are correctl...

Although SoC design space exploration requires retargetable tools and real-time constraint awareness, conventional compiler infrastructure barely provides both. This paper proposes a novel, automatically retargetable, timeconstraint aware instruction scheduler to fulfill both needs. The tool is based upon a unified representation of instruction precedence and timing constraints. It relies on a ...

An algorithm for inversion in GF(2) suitable for implementation using a polynomial multiply instruction on GF(2) is proposed. It is based on the extended Euclid’s algorithm. In the algorithm, operations corresponding to several contiguous iterations of the VLSI algorithm proposed by Brunner et al. is represented as a matrix. They are calculated at once through the matrix efficiently by means of...
