A large portion of the embedded system development process involves the integration of hardware and software. Unfortunately, communication across the hardware/software boundary is tedious and error-prone to create. This paper presents an automatic hardware/software interface generation system. As the front-end of hardware/software co-design frameworks, a system designer defines XML specifications for hardware functions. Our system generates hardware/software interfaces including Device Driver, Driver API, and Device Controller from these specifications. Embedded software designers can easily use hardware just like system libraries. Our system reduces the mistakes and errors that can be occurred when a software programmer directly connects software to hardware, and supports balancing labors between hardware developers and software programmers. Moreover, this system can be used as the back-end for a hardware/software co-design framework.

The discipline of software performance is very broad; it influences all aspects of the software development lifecycle, including architecture, design, deployment, integration, management, evolution and servicing. Thus, the complexity of software is an important aspect of development and maintenance activities. Much research has been dedicated to defining different software measures that capture what software complexity is. In most cases, the description of complexity is given to humans in forms of numbers. These quantitative measures reflect human-seen complexity with different levels of success. Software complexity growth has been recognized to be beyond human control. In this paper, we have focused our discussion on the increasing software complexity and the issue with the problems being faced in managing this complexity. This increasing complexity in turn affects the software productivity, which is declining with increase in its complexity.

The problem surrounding methods of implementing the software testing process has come under the spotlight in recent times. However, as compliance with the software testing process does not necessarily bring with it immediate economic benefits, IT companies need to pursue more aggressive efforts to improve the process, and the software industry needs to makes every effort to improve the software testing process by evaluating the Test Maturity Model integration (TMMi). Furthermore, as the software test process is only at the initial level, high-quality software cannot be guaranteed. This paper applies TMMi model to Automobile control software testing process, including test policy and strategy, test planning, test monitoring and control, test design and execution, and test environment goal. The results suggest improvement of the automobile control software testing process based on Test maturity model. As a result, this study suggest IT organization's test process improve method.

With the advent of the Fourth Industrial Revolution, software(SW) education has become a necessity, not a choice of those who live in the digital age. Recently, many countries around the world have been actively promoting software education based on Computational Thinking(CT) for K-12 students, so software education in schools has bigger meaning as basic literacy education of future digital generation rather than coding skills. However, the integration of software education as a formal curriculum in schools is still ongoing in even other countries. Korea is also pursuing software education, but it is in the beginning stage. Therefore, we need to study the cases of other countries that have already started software education at the national level. In this paper, we first investigate the software education cases of three countries, e.g., UK, France and China with a respect of background & educational objective, development stage, and curriculum and we suggest education policies that software education can settle in Korea schools to foster a creative talented people.

항공용 SIL은 항공전자시스템의 통합 및 검증에 사용되는 통합시험환경이다. 항공용 SIL에는 여러 가지 제약으로 인해 항공기에 탑재되는 장비를 직접 연동할 수 없을 때 장비의 소프트웨어 모델이 필요하다. 지금까지 항공기 개발에 적용한 항공용 SIL의 소프트웨어 모델은 표준화된 방법 없이 일반적인 소프트웨어 개발 방법의 적용으로 재사용이 어려워 소프트웨어 모델 재사용을 위한 프레임워크의 필요성이 제기되었다. 이러한 항공용 SIL 모델의 표준화된 모델링 방법을 위해 DEVS (discrete event system specification) 형식론을 채용하였다. DEVS 형식론은 이벤트 구동(event-driven) 알고리즘이며 이는 기존의 항공용 SIL에 적용되는 절차적이고 반복적인 알고리즘과 어울려 동작하기 힘들다. 이에 본 논문에서는 항공용 SIL 모델의 특징과 기존 방식이 가지는 한계를 보완하고 모델의 재사용성을 극대화할 수 있는 이벤트 기반의 모델링 방법과 실시간 시뮬레이션 방법을 제안한다.

The rapid growth of communication and globalization has changed the software engineering process. Security has become a crucial component of any software system. However, software developers often lack the knowledge and skills needed to develop secure software. Clearly, the creation of secure software requires more than simply mandating the use of a secure software development lifecycle; the components produced by each stage of the lifecycle must be correctly implemented for the resulting system to achieve its intended goals. This study demonstrates that a more effective approach to the development of secure software can result from the integration of carefully selected security patterns into appropriate stages of the software development lifecycle to ensure that security designs are correctly implemented. The goal of this study is to provide developers with an Integrated Security Development Framework (ISDF) that can assist them in building more secure software.

요구분석 및 설계 단계를 거쳐 구현된 탑재소프트웨어는 오류를 제거하고 요구규격에 맞도록 모든 기능이 정확히 구현되었는지 확인하기 위한 여러 가지 시험절차를 거치게 되는데, 일반적으로 단위시험, 통합시험, 검증시험 순으로 진행된다. 단위시험은 보통 개인 PC 환경에서 타겟 시뮬레이터를 이용하여 수행되고, 통합 및 검증시험은 목표시스템과 유사한 조건에서 수행할 수 있도록 하드웨어 환경을 제공하는 소프트웨어 검증장치를 이용하여 수행된다. 본 논문에서는 차세대 저궤도위성 탑재소프트웨어 시험환경에 대한 것으로 시험절차와 시험도구, 탑재소프트웨어 검증장치에 대하여 기술한다.
