PLX is a concise instruction set architecture (ISA) that combines the most useful features from previous generations of multimedia instruction sets with newer ISA features for high-performance, low-cost multimedia information processing. Unlike previous multimedia instruction sets, PLX is not added onto a base processor ISA, but designed from the beginning as a standalone processor architecture...

In recent years, the success of Internet and World Wide Web, and the growing feasibility of image and video compression techniques have pushed multimedia into mainstream computing. These requirements necessitate new and modified hardware architectures enabling realtime multimedia applications. Three methods have been proposed for enhancing multimedia architectures namely dedicated processors, m...

In this chapter, we present contemporary VLSI processor architectures that support multimedia applications. We classified these processors into two groups: dedicated multimedia processors, which perform dedicated multimedia functions, such as MPEG encoding or decoding, and general-purpose processors that provide support for multimedia. Dedicated multimedia processors use either function-specifi...

this study investigated the effect of applying the dynamic system theory (dst) and cognitive linguistics (cl) insights into grammar instruction on efl learners’ learning of english prepositions and learner autonomy. sixty iranian efl learners at the lower-intermediate level of language proficiency were randomly assigned to 1 experimental and 1 control group. the 2 groups filled out an autonomy ...

In this paper, a review of the role of input, output and instruction in second language acquisition is provided. Several pedagogical interventions in grammar instruction (e.g., processing instruction, input enhancement, structured output and collaborative output tasks) are presented and their effectiveness reviewed. A final and overall evaluation is provided at the end of the paper.

this paper examines the role of the structural syllabus in efl settings, particularly efl classes in iran. the paper starts with an overview of what the structural syllabus is. afterwards, the shortcom-ings of the structural syllabus are reviewed. next the role of formal grammar instruction is discussed in depth. finally it is suggested that because of the crucial role that grammar instruction ...

This paper describes recent large-scale-integration programmable processors designed for multimedia processing such as real-time compression and decompression of audio and video as well as the generation of computer graphics. As the target of these processors is to handle audio and video in real time, the processing capability must be increased tenfold compared to that of conventional microproc...

Display grammar is a coupling of semantic and signal processing information for interactive multimedia. We propose a computational formalization binding media resource data and authoring information, including contextual data and interactive processing algorithms. We hypothesize display grammar provides a domain for mapping a range of applications of MMIE and media resource retrieval. We demons...

How can we help students to understand scientific explanations of cause-and-effect systems, such as how a pump works, how the human respiratory system works, or how lightning storms develop? One promising approach involves multimedia presentation of explanations in visual and verbal formats, such as presenting computer-generated animations synchronized with computer-generated narration or prese...
