Network-on-Chip (NoC) architectures have emerged as the solution to the on-chip communication challenges of multi-core embedded processor architectures. Design space exploration and performance evaluation of a NoC design requires fast simulation infrastructure. Simulation of register transfer level model of NoC is too slow for any meaningful design space exploration. One of the solutions to reduce the speed of simulation is to increase the level of abstraction. SystemC TLM2.0 provides the capability to model hardware design at higher levels of abstraction with trade-off of simulation speed and accuracy. In this thesis, SystemC TLM2.0 models of NoC routers are developed at three levels of abstraction namely loosely-timed, approximately-timed, and cycle accurate. Simulation speed and accuracy of these three models are evaluated by a case study of a 4x4 mesh NoC.

While English language education has become increasingly prominent worldwide, countries have adopted various initiatives to increase English language development. One country making a push for English language development is Taiwan; however, current educational practices and values can prove to be challenges in implementing new methods. For example, although Communicative Language Teaching (CLT) methods gained popularity starting in the 1990s, they have been slow to take hold in Taiwan. Additionally, Taiwan’s Ministry of Education is pushing for bilingualism by the year 2030, introducing curricular reforms and new strategies to increase the prominence of English on a social level. In order to analyze current educational methods and practices in Taiwan, as well as predict the efficacy of new strategies, this study focused on gathering the perspectives and experiences of the students themselves. International students were specifically targeted, as they have had exposure to multiple educational environments, as well as firsthand experience applying their English language knowledge in an immersive environment. To gather student perspective, an online survey was made available to Taiwanese international students currently studying in a U.S. university. Respondents were asked multiple-choice questions on curricular focus, as well as short answer questions regarding their educational experiences. Overall, the respondents showed an agreement in regards to the heavy emphasis of reading, writing, and grammar in Taiwan, which they correlated directly with high-stakes exams, particularly the university entrance exam. They also noted the lack of speaking and listening practice, as well as a strong desire to apply English in a communicative sense. These observations hold significant implications for various stakeholders, including teachers, principals, curriculum developers, exam designers, and university admissions.
