The performance degradation caused by branch instructions in pipelined computers is well known. The degradation is even greater on computers with multiple pipelines processing a single instruction stream, such as superscalar and scalable compound instruction-set machines (SCISM). Several branch prediction schemes have been proposed that attempt to reduce this performance penalty. One of these {...

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...

MINI-GRAPH PROCESSING Anne Weinberger Bracy Amir Roth For years, single-thread performance was the most dominant force driving processor development. In recent years, however, the poor scaling of single-thread superscalar performance and power concerns coupled with the ever-increasing number of transistors available on chip has changed the focus from single-thread performance to thread-level pa...

This study investigates how different form-focused instruction (FFI) timing impacts English as a foreign language (EFL) learners’ grammar development. A total of 169 Chinese middle school learners were assigned to four conditions randomly: control, before-isolated FFI, integrated and after-isolated FFI. The three experimental groups received treatments which combined form meaning with the passi...

Effective global instruction scheduling techniques have become an important component in modern compilers for exposing more instruction-level parallelism (ILP) and exploiting the everincreasing number of parallel function units. Effective register allocation has long been an essential component of a good compiler for reducing memory references. While instruction scheduling and register allocati...

Abstract This study was an attempt to investigate the effect of collaborative form-focused activities on grammar learning of elementary EFL learners. To this end, 58 adult male Iranian EFL learners at elementary level of proficiency in three classes of language institutes were chosen. They formed the three groups of the study. The grammar section of Cambridge Michigan Placement test was used to...
