Performance Comparison of Asynchronous Adders1
نویسنده
چکیده
In asynchronous systems, average function delays principally govern overall throughput. This paper compares the performance of six adder designs with respect to their average delays. Our results show that asyn-chronous adders (32 or 64-bits) with a hybrid structure (e.g., carry-select adders) run 20-40% faster than simple ripple-carry adders. Hybrid adders also outper-form high-cost, strictly synchronous conditional-sum adders.

Impact of Dynamic Assessment on the Writing Performance of English as Foreign Language Learners in Asynchronous Web 2.0 and Face-to-face Environments
This study sought to investigate dynamic assessment (DA) - an assessment approach that embeds inter- vention within the assessment process and that yields information about the learner’s responsiveness to this intervention - and the writing performance of the second language (L2) learners in Web 2.0 contexts. To this end, pre and post-treatment writings of 45 par...

The present study was an attempt to investigate the significance of environmental changes on the develo p- ment of writing in English as a Foreign Language (EFL) context with respect to the individual. This study also compared the impacts of collaboration and asynchronous computer mediation (ACM) on the writing complexity of EFL learners. To this end, three intact writing classes were designate...
متن کاملBit Error Performance for Asynchronous Ds Cdma Systems Over Multipath Rayleigh Fading Channels (RESEARCH NOTE)
In recent years, there has been considerable interest in the use of CDMA in mobile communications. Bit error rate is one of the most important parameters in the evaluation of CDMA systems. In this paper, we develop a technique to find an accurate approximation to the probability of bit error for asynchronous direct–sequence code division multiple–access (DS/CDMA) systems by modeling the multipl...

This study aims at investigating the effect of dynamic assessment (DA) on L2 writing achievement if applied via blogging as a Web 2.0 tool, as well as examining which pattern of interaction is more conducive to learning in such an environment. The results of the study indicate that using weblogs to provide mediation contributes to the enhancement of the overall writing performance, vocabulary a...
متن کاملApplications of Asynchronous Circuits
| A comparison with synchronous circuits suggests four opportunities for the application of asynchronous circuits: high performance, low power, improved noise and EMC properties, and a natural match with heterogeneous system timing. In this overview article each opportunity is reviewed in some detail, illustrated by examples, compared with synchronous alternatives, and accompanied by numerous p...
