This paper reports on a study thatinvestigated Iranian EFL high school students’ perceptions of written grammar feedback to specify their reasons for preferring comprehensive or selective feedback and choosing some feedback strategies. A questionnaire was administered to 100 EFL intermediate high school students who were selected based on their scores on a proficiency test. Moreover, semi-struc...

Real-time operation of signal processing applications on multimedia RISC processors is often limited by high instruction cache miss rates of direct-mapped caches. In this paper, a heuristic approach is presented which reduces high instruction cache miss rates in direct-mapped caches by code positioning. The proposed algorithm rearranges functions in memory based on trace data so as to minimize ...

This paper describes how media processing programs may be accelerated by using the multimedia instruction extensions that have been added to general-purpose microprocessors. As a concrete example, it describes MAX2, a minimalist, second-generation set of multimedia instructions included in the PA-RISC 2.0 processor architecture. MAX2 implements subword parallel instructions, which utilize the m...

This study was to explore facilitative function of using multimodal channels over single channel presentation and comprehension of idiomatic expressions to Iranian EFL intermediate proficiency learners. Out of a pool of 90, sixty intermediate participants were homogenized by a QPT test, using a quasi-experimental design. They were randomly assigned to three equal groups: WhatsApp-, SMS- and Cla...

The main rivals to the input or comprehension hypothesis are the skill-building and comprehensible output hypotheses. Studies claiming to show that the skill-building hypothesis is correct consist of studies of the impact of grammar instruction and error correction. These studies show only that instruction and correction have a modest impact on tests in which subjects are focused on form. Compr...

Objective: The goal of this project is to evaluate the effectiveness of two different techniques for exploiting the Instruction Level Parallelism (ILP) available in Digital Signal Processing (DSP) and Multimedia applications. VLIW (Very Long Instruction Word) architectures have multiple functional units to take advantage of such a parallelism, while the SIMD (Single Instruction Multiple Data) a...

"Interactive" and "interactivity" are some of the most commonly used terms in instruction. For example, we are often told that multimedia (among other emerging technologies) is superior to "traditional" instruction, often because it is "interactive." However, the term interactivity is a loosely defined term that, according to Rose (1999), seems to deconstruct itself when closely examined. Her i...
