Design of a High-Performance On-Chip Bus
Fred Adu Kumi,Seung-yong Park,Kwangki Ryoo 한국정보통신학회 2016 2016 INTERNATIONAL CONFERENCE Vol.8 No.1
In this paper, we propose a high-performance on-chip bus for system-on-chip design. The proposed bus is made up of two channels which allows simultaneously transactions to occur. Each channel has separate read and write buses and can also perform concurrent read and write transactions. The arbiter is designed to grant access based on the availability of the channel and the target slave. The proposed bus is designed at RTL with Verilog HDL using Xilinx ISE 14.7 and simulated with Modelsim and tested on HBE-SoC-IPD board equipped with Virtex-4 FPGA. Various tests are performed and the results are compared with AMBA AHB.
멀티미디어 플레이어를 위한 RapidPLUS 기반 가상 프로토타이핑 설계 및 구현

프로토타이핑 시스템 설계에서 프로토타이핑은 실제 모델과 같은 초기 모형을 뜻하는 것으로 개발 초기에 시스템의 모형을 간단히 만들어 사용자에게 제시하여 사용자로 하여금 실제 작동시켜 기능의 추가, 변경 내지 삭제를 요구하도록 하여 시스템을 점차적으로 개선시켜 나가도록 하는 방식을 말한다. 가상 프로토타이핑은 임베디드 소프트웨어 개발 초기단계에서 사용자 혹은 의뢰자의 요구사항들을 효과적으로 추출할 수 있도록 고안된 시스템 요구 및 제약조건 추출 방법론이다. 본 논문에서는 가상 프로토타이핑 기법을 이용하여 멀티미디어 플레이어의 다양한 기능을 시뮬레이션 할 수 있는 가상 프로토타입을 설계 및 구현한다.

Background: Insufficient training in infection control and occupational health among healthcare workers (HCWs) in countries with high human immunodeficiency virus (HIV) and tuberculosis (TB) burdens requires attention. We examined the effectiveness of a 1-year Certificate Program in Occupational Health and Infection Control conducted in Free State Province, South Africa in an international partnership to empower HCWs to become change agents to promote workplace-based HIV and TB prevention. Methods: Questionnaires assessing reactions to the program and Knowledge, Attitudes, Skills, and Practices were collected pre-, mid-, and postprogram. Individual interviews, group project evaluations, and participant observation were also conducted. Quantitative data were analyzed using Wilcoxon signed-rank test. Qualitative data were thematically coded and analyzed using the Kirkpatrick framework. Results: Participants recruited (n = 32) were mostly female (81%) and nurses (56%). Pre-to-post-program mean scores improved in knowledge (+12%, p = 0.002) and skills/practices (+14%, p = 0.002). Preprogram attitude scores were high but did not change. Participants felt empowered and demonstrated attitudinal improvements regarding HIV, TB, infection control, and occupational health. Successful projects were indeed implemented. However, participants encountered considerable difficulties in trying to sustain improvement, due largely to lack of pre-existing knowledge and experience, combined with inadequate staffing and insufficient management support. Conclusion: Training is essential to strengthen HCWs' occupational health and infection control knowledge, attitudes, skills, and practices, and workplace-based training programs such as this can yield impressive results. However, the considerable mentorship resources required for such programs and the substantial infrastructural supports needed for implementation and sustainability of improvements in settings without pre-existing experience in such endeavors should not be underestimated.
