While analyzing currently available international research about embedded system development, it seems that as the complexity of embedded systems is continuously increasing, the major problems regarding their development remain always the same: vague requirements, insufficient time to develop, lack of resources, and complexity management. With the focus on the development process, it is shown, with examples coming from 20 years of experience, the industry perspective of a company managing such problems by adopting a consolidated set of good practices.

The growing complexity of today's embedded systems demands new methodologies and tools to manage the problems of analysis, design, implementation, and validation of complex-embedded systems. Focusing on this issue, this paper describes a design and implementation toolset using our ODYSSEY methodology, which advocates object-oriented (OO) modeling of embedded systems and its ASIP-based implementation. The proposed approach promotes a smooth transition from high-level object-oriented specification to the final embedded system, which is composed of hardware and software components. The transition from higher to lower abstraction levels is facilitated by the use of our GUI, which supports the intermediate steps of the design and implementation process. In order to illustrate the proposed approach and related toolset, we apply this top-down design and implementation framework to real-world embedded systems, namely JPEG codec and Motion JPEG codec. Experimental results show that the developed tool remarkably decreases the design and verification time with modest performance penalty.

ABSTRAKDevOps mendorong percepatan pengembangan sistem. Namun bukti nyata penerapannya pada sistem tertanam belum mencukupi. Salah satu penyebabnya adalah kesulitan proses deployment pada perangkat. Konsep IoT menghubungkan sistem tertanam dengan jaringan yang memungkinkan proses pembaharuan firmware menggunakan mekanisme Over The Air (OTA). Tulisan ini mengusulkan infrastruktur DevOps untuk pengembangan sistem tertanam. Perangkat keras yang digunakan adalah microcontroller ESP8266. Sedangkan lingkungan DevOps menggunakan perangkat lunak PlatformIO, GitHub dan Travis CI. Pengujian dilakukan dengan mengubah user requirement yang kemudian diterapkan pada perangkat keras. Tahapan DevOps (build and test, release hingga deploy) telah berhasil dilakukan secara otomatis. Sistem mampu mendeteksi kesalahan penulisan kode sumber. Rerata waktu keseluruhan proses adalah 77,21 detik. Proses build and test mendominasi waktu proses dengan rerata sebesar 77,21 detik dan waktu deploy memiliki rerata 1,41 detik.Kata kunci: IoT, Sistem Tertanam, OTA, DevOps, ESP8266 ABSTRACTDevOps drives the acceleration of system development. However, the concrete evidence of its application in embedded systems is not sufficient. One of the causes is difficulty in the deployment process on the device. Firmware update using an Over-The-Air (OTA) mechanism is allowed by the IoT concept that connects embedded systems into a network. This paper is proposing a DevOps infrastructure for embedded system development. Proposed infrastructure using ESP8266 for the hardware and PlatformIO, GitHub, and Travis CI for the DevOps environment. Testing the proposed system is done by changing the user requirements that are applied to the hardware. The DevOps stages from building and test, release, and deployment have automatically been done. The system is also able to detect developer errors in writing source code. The average time of the whole process on trial was 77.21 seconds. The build and test process dominates the processing time with an average of 77.21 seconds and the deployment time is relatively short with an average of 1.41 seconds.Keywords: IoT, Embedded System, OTA, DevOps, ESP8266

Development Methods

Agile development methods are widely utilized in software development. There is a growing interest and effort to introduce them to other areas of technology, such as development of space systems. Space systems are typically safety- and mission-critical and therefore their development is strongly regulated and standardized. European Cooperation for Space Standardization (ECSS) has created a collection of standards which are extensively followed mainly in European space projects. In this paper, a review and discussion are presented to find out the conflicts between the agile development and the ECSS standards. The presented analysis and discussion show that the ECSS standards do not fully prevent the utilization of agile methods. However, there are aspects to be taken into account in the development methods, contracts and tailoring of standards.

Embedded systems are extensively used in the field of pervasive computing. These systems are used to such an extent that embedded systems are now controlled and monitored from remote locations by using Web services. Internet authorities are able to assign every device a unique Internet protocol address with the introduction of IPv6 on the Web. Peer-to-peer communication between Internet-enabled devices helped Web services to make performance improvement. On the worse side, it created new attacks on the components used in the embedded systems. The chapter discusses the details of security issues on a Web-enabled embedded system used in greenhouse environment. The devices used in greenhouse environment are monitored and controlled by different software components used in the entire system. Various vulnerabilities are introduced during entire development process of the greenhouse environment. The problem is to search the real threats, then define security policies and implement them during development process. The chapter discusses most of the vulnerabilities of a generalized greenhouse project and tries to find out possible security techniques to deal with the vulnerabilities. Instead of showing the design to build a greenhouse embedded system, it shows to introduce security policies at various levels of life-cycle, be it before development, during development, or after development.

In most industrial embedded systems development projects, the software and the hardware development parts are separated, and the constraint requirements/capabilities are informally exchanged in the system development phase of the process. To prevent failures due to the violation of timing constraints, hardware components of the platform are typically over dimensioned for the capabilities needed. This increases both cost and power consumption. Performance analysis is not done sufficiently at early stages of the development process to optimize the system. This chapter presents results of the integration of tools and extra modeling to offer new performance analysis capabilities in the early stages of the development process. These results are based on trace generation from code instrumentation. A number of enhancements were made, spanning the system modeling stage down to the execution stage (based on an ARM dual core Cortex A9-based target board). Final results taken from a software-based radio case study (including the analysis and validation stages) are presented.

The Agile software development process offers many potential benefits, including a design approach that allows frequent customer input, rapid development of functionality, and the ability to identify and resolve potential misunderstandings in design requirements. This process has generally been highly successful and offered many benefits to the software development industry. It is being adopted by an ever-increasing number of industries and used for applications beyond software development, including hard ware development, training materials, and marketing materials, to name a few examples. This paper describes a project to examine the integration of Human-Centered Design principles with the Agile process, and evaluate the appropriateness of this integrated process for safety and mission critical systems design.

Since the boot code locates in the bottom of embedded system, so the design of boot code is the key technology and the important steps of system development during the development process of embedded system. Although the boot code supporting new framework has been updating, the boot code of manufacturer giving is an old version of a few years ago in the current market popular embedded products. So this paper analyzes the U-boot code commonly used and in the popular in detail, combining with the startup process of embedded Linux system, then, this paper gives a process, transplanting the new version of U-boot code using the UT6410 as development platform. On the basis of completing the basic function transplantation, this paper adds the network card and DNW. Experiments show that the new version of transplantation can run smoothly, and improve the efficiency of the system.
