Proper use of native signal processing (NSP) instruction set enhancements can result in speedup for targeted applications. In this paper, we study the behavior of the X86 architecture's Multimedia Extension (MMX) instruction set on signal processing and multimedia algorithms and applications. In addition to quantifying speedup, we make comparisons based on detailed dynamic instruction pro ling....

This response to Azar (this volume) intends to discuss from an academic's perspective the main points raised in her paper (i.e., grammar-based instruction and its relation to focus on form and error correction) and, to encourage a more concept-based approach to grammar instruction (CBT). A CBT approach to language development argues that the conceptual nature of grammatical forms is best expres...

This study is an investigation of the use of multimedia components such as visual text, spoken text, and graphics in a Web-based self-instruction program to increase learners’ English vocabulary learning at Myungin Middle School in Seoul, South Korea. A total of 172 middle school students (14 years of age) in five classes participated in the study. Each individual was required to complete sever...

Reconfigurable instruction set processors can potentially reduce the power consumption of high performance multimedia applications by fusing the concept of a reconfigurable array with a programmable processor. In particular, VLIW processors with coarse-grained reconfigurable functional units are specially suited to low power multimedia applications. Code generation for this type of processors i...

ITS instruction may be enhanced by models of student motivation and mood, in addition to cognitive skills and domain knowledge. In an initial study, self-assessments by high school students of their mathematics motivation and mood showed gender differences in response to ITS instruction, and predicted students' intention to learn from the ITS and use of multimedia help features.

There has been relatively little analytical work on processor optimizations for multimedia applications. With the introduction of MMX by Intel, it is clear that this is an area of increasing importance. Building on previous work [4, 5, 6, 7, 13, 14], we propose optimizations for multimedia architectures that support independent parallel execution of instructions within dynamically assembled tra...

Cognitive load theory (CLT) is gaining increasing importance in the design and evaluation of instruction, both traditional and technology based. Although it is well understood as a theoretical construct, the measurement of cognitive load induced by instructional materials in general, and by multimedia instruction in particular, mainly relies on methods that are either indirect, subjective, or b...

The purpose of this study was to investigate the relationship between Extension employees' learning styles and their performance in three different types of learning environments: traditional face-to-face instruction, minimally interactive online instruction, and highly interactive, multimedia-rich online instruction. Keith Golay's Learning Pattern Assessment and a ten-question post-test were u...

This paper investigates the potential for automatic mapping of typical embedded applications to architectures with multimedia instruction set extensions. For this purpose a (pattern matching based) code transformation engine is used. The experiments show that about 85% of the loops which are suitable for Single Instruction Multiple Data (SIMD) parallelization can be automatically recognized and...
