Abstract:

Sejak diperkenalkan oleh Linus Torvalds, bahasa pemograman Linux dengan sifatnya yang terbuka, telah dikembangkan oleh begitu banyak pihak secara bersama-sama. Pihak-pihak ini adalah para akademisi, industri maupun perorangan dengan bakat dan keahlian yang luar biasa, dan dengan berbagai berkepentingan. Hasilnya adalah sesuatu yang sangat besar, baik pada segi kapasitas maupun kwalitas. Dengan kapasitas yang begitu besar, tidaklah semua terpakai pada suatu rancangan produk. Sehingga menjadi salah satu karakteristik Linux, fleksibilitas. Yaitu Sistem Operasi dapat diubah sesuai kebutuhan. Kernel Linux yang banyak dipakai sekarang pada beberapa embedded systems berbasis prosesor ARM, yaitu sebagai penggerak robot, alat-alat komunikasi dan sebagainya, dengan sendirinya menuruni sifat fleksibilitas ini. Maka terkadang pengguna masih memerlukan menambahkan atau mengubah isi kernel Linux tersebut, misalnya dengan salah satu tujuan: sudah terjadinya inisialisasi service tertentu setelah ‘booting’.

Abstract:

Embedded devices are often used at remote locations. Accordingly, since it is difficult and costly to physically access the devices for firmware updates, the updates are made with Over-the-Air (OTA). OTA is a firmware update method that allows embedded devices to be updated wirelessly without requiring physical access. OTA applications for Embedded Linux devices are platform-dependent. Therefore, the aim of this study is to develop an easy integrated, steady, and robust OTA method. This method runs in the background without any user action on a platform-independent Embedded Linux device and it has a small footprint. The firmware is compressed in this method. The compressed firmware is uploaded to a storage area such as a remote drive, cloud, and repository. The storage area is used efficiently thanks to compressed firmware. The OTA application checks versions of firmware in the storage area and compares them with firmware running on the device. It decides which version is more up-to-date. If the version of the firmware in the storage area is more up-to-date, the OTA application runs in the background and downloads the updated firmware without interfering with the working functions on the device. After the download is completed, compressed firmware is extracted and flashed into the specified memory location. When the device is rebooted after the procedure is completed, the device is going to boot with the new version of the firmware. Consequently, the OTA application can be integrated easily on most Embedded Linux platforms. Besides the OTA application can be enhanced with security and power-safe features.

Abstract:

This work investigates the real-time performance of Linux kernels and distributions with a PREEMPT_RT real-time patch on ARM-based embedded devices. Experimental measurements, which are mainly based on heuristic methods, provide novel insights into Linux real-time performance on ARM-based embedded devices (e.g., BeagleBoard and RaspberryPi). Evaluations of the Linux real-time performance are based on specific real-time software measurement modules, developed for this purpose, and the use of a standard benchmark tool, cyclictest. Software modules were designed upon the introduction of a new response task model, an innovative aspect of this work. Measurements include the latency of response tasks at user and kernel space, the response on the execution of periodic tasks, the maximum sustained frequency and general latency performance metrics. The results show that in such systems the PREEMPT_RT patch provides more improved real-time performance than the default Linux kernels. The latencies and particularly the worst-case latencies are reduced with real-time support, thus making such devices running Linux with PREEMPT_RT more appropriate for use in time-sensitive embedded control systems and applications. Furthermore, the proposed performance measurements approach and evaluation methodology could be applied and deployed on other Linux-based real-time platforms.

Abstract:

Linux is a kernel whose development has been very active since it was first released to the public. With a large community, Linux development has penetrated into various fields in the world of computerization, including personal computers. Today, Linux can be used on a variety of devices from personal computers to embedded systems. The development is very active thanks to the large community and Linux adopting open source, many developers are making their own version of the Linux-based operating system. Versions and types of Linux-based operating systems are called distros or distributions. The number of versions and types of Linux-based operating systems, of course, confuses users who are trying Linux for the first time or who want to fully switch to Linux from another operating system. Decision support systems can provide alternative solutions for those users who are confused about choosing a Linux distribution. By using the Simple Additive Weighting (SAW) method, the existing criteria can be used as benchmarks in determining the Linux distribution of choice and therefore the accuracy of the system can exceed 90%

Abstract:

The aim of this research was to analyze the application of fuzzy C-means (FCM) algorithm-based ARM-Linux-embedded system in magnetic resonance imaging (MRI) images for prediction of brain tumors. The optimized FCM (OFCM) algorithm was proposed based on kernel function, and the ARM-Linux-embedded imaging system was designed under ARM9 chip and Linux recorder, which were applied in MRI images of brain tumor patients. It was found that the sensitivity, specificity, and accuracy of the OFCM algorithm (90.46%, 88.97%, and 97.46%) were greater obviously than those of the deterministic C-means clustering algorithm (80.38%, 77.98%, and 85.24%) and the traditional FCM algorithm (83.26%, 79.56%, and 86.45%), and the difference was statistically substantial ( P < 0.05 ). The ME and running time of the OFCM algorithm decreased sharply in contrast to those of the deterministic C-means clustering algorithm and the traditional FCM algorithm ( P < 0.05 ). There were great differences in fraction anisotropy (FA) and mean diffusion (MD) of tumor parenchymal area, surrounding edema area, and normal white matter area ( P < 0.05 ). FA of stage III+IV was smaller than those of stage I and II ( P < 0.05 ), while the apparent diffusion coefficient (ADC) of stage III+IV was greater than that of stage I and II ( P < 0.05 ). In conclusion, the poor update data processing and low data clustering efficiency of FCM were solved by OFCM. Moreover, computational efficiency of ARM-Linux-embedded imaging system was improved, so as to better realize the prediction of brain tumor patients through ARM-Linux-embedded system based on adaptive FCM incremental clustering algorithm.

Abstract:

This paper presents an improvement of control flow attestation (C-FLAT) for Linux. C-FLAT is a control attestation system for embedded devices. It was implemented as a software executing in ARM’s TrustZone on bare-metal devices. We extend the design and implementation of C-FLAT through the use of a type 2 Nanovisor in the Linux operating system. We call our improved system “C-FLAT Linux”. Compared to the original C-FLAT, C-FLAT Linux reduces processing overheads and is able to detect the SlowLoris attack. We describe the architecture of C-FLAT Linux and provide extensive measurements of its performance in benchmarks and real-world scenarios. In addition, we demonstrate the detection of the SlowLoris attack on the Apache web server.
