Current media ISA extensions such as Sun’s VIS consist of SIMD-like instructions that operate on short vector registers. In order to exploit more parallelism in a superscalar processor provided with such instructions, the issue width has to be increased. In the Complex Streamed Instruction (CSI) set exploiting more parallelism does not involve issuing more instructions. In this paper we study h...

The rapid moving of computing into multimedia leads computers to include special instructions to support multimedia operations, including those with RISC architectures[5,6]. Multimedia performance now becomes a pseudo-benchmark for modern processors. This paper presents such benchmark in HISC, which stands for Highlevel Instruction Set Computer [1,2]. HISC is a generalpurpose descriptor compute...

This study considers the ongoing “grammar correction debate” in second language writing by examining how a focus on formal accuracy would affect the revising processes of ESL writers and the students’ written products. A case study approach was used to find out how two ESL students would respond in the two different rewriting situations: (a) when there is no explicit expectation for them to pro...

In the last decade, the practice of English Language Teaching (ELT) in China’s classrooms has been greatly influenced by western-oriented innovations in Second Language Teaching (SLT) pedagogy. SLT methods focusing on meaning and communicative tasks have been introduced and have become superfluous throughout the country, outdating the traditional grammar-centered instruction. However, the decis...

This project provides a sample of the curriculum, Rapping English, which uses rap/hip-hop style music to teach ELLs vocabulary, grammar, discourse and prosody. The rationale for using musical instruction is based on Gardner’s (2006) multiple intelligence theory and Bloom’s (1978) learning domains. This curriculum instructs students through musical intelligence and the affective domain which are...

Next generation multimedia mobile phones that use the high bandwidth 3G cellular radio network consume more power. Multimedia algorithms such as speech, video transcodecs have very large instruction foot prints and consequently stalled due to instruction cache misses. The conflicts in on-chip caches contribute a large fraction of the CPU cycle penalty and hence increase in power consumption. Ma...

In this paper, we propose a general-purpose multimedia query language that is built upon a set of generalized n-ary spatio-temporal relations and object-oriented modelling paradigm for multinnedia data. We present a grammar for the query language and elaborate how various functiona;!ities such as declartion of multimedia data, specification of spatio-temporal logic, expressio~l of spatio-tempor...
