The effective integrated approach for modeling of functional devices (FD), airborne computers and embedded systems on the devices design stage is proposed. This approach can be used at the manufacturers, which have a full production cycle, especially in the following industrial systems: instruments for onboard information processing and control, space systems, aviation systems and others. In the traditional...
The concept of embedded systems is considered. The advantages of developed embedded systems compared to general purpose are emphasized. The possible ways to develop microcontroller-based embedded systems design tools are analyzed. The features provided by MCU manufacturers are touched upon. The authors investigate the case of development of equipment for education, research and design of embedded...
ARM embedded system can achieve a higher degree of integration, it has the advantages of small volume and low power consumption, which has gradually become one of the important products of information industry. In this paper, we introduce the overall design scheme of ARM and software. We provide an efficient solution to meet the request of even text materials when using camera. To turn on the camera...
Embedded systems for wearable robotics are ideally low-cost, lightweight, miniature, reliable and safe. They have high peak output and negligible standby power, are simple to use and program, can support high-performance real-time control loops and accept additional degrees of freedom, input and output devices. However, practical solutions cannot accommodate all of these criteria and compromises are...
This study utilizes a simple model for constructing sensor nodes — master controller combinations in the Internet of Things. The model combines hardware and software for embedded systems which measure a predefined set of parameters. The master controller manages several sensor nodes, collects data from them and provides data for clients. The paper introduces a proof-of-concept implementation based...
One of the most promising areas in Computer Engineering is certainly that of the Internet of Things (IoT) Systems. Moreover, such systems can be efficiently implemented in current Field Programmable Gate Arrays (FPGAs) comprising of either soft-core or hard-core CPUs. The design of an IoT system comprises of developments in both hardware and software whereas a productive IoT Systems Designer should...
We aim at developing software techniques which enables 32-bit transiently powered embedded systems to make progress across periods of energy unavailability without resorting to hardware modifications. Recently, we have seen a huge surge in wearable and smartbuilding centric sensing applications. However, these devices are integrated with batteries for charging which not only increases size and mass...

This device ensures correct communication between local units and central command unit. The first part sets Slave device position in the monitoring system, and then there it is a detailed description of the hardware parts of the device. Main algorithms are presented as the basis...
Embedded System Curriculum at Tsinghua University is target at advanced undergraduate senior students in CS department. At the end of this course, an overall understanding about System is expected to be obtained by students who have gotten perfect software knowledge from software series curriculums and hardware knowledge from hardware series curriculums. Embedded System is unique for its close association...
In the current electronic industry, embedded systems have become essential components in most electronic devices. The fast growth mobile devices have been used in every sector and brought wide applications in many aspects of our society. These devices involve in internet connections, wireless communications and even cloud computing, which increases the necessity of both hardware and software securities...
One of the methods for improving reliability of embedded systems is control-flow checking (CFC) of the running program. Embedded systems often use hardware or software CFC methods depending on the application. Division of checking parts into software and hardware can increase the system performance when the basic blocks are carefully selected. This paper presents a design of a new hybrid control-flow...
This paper presents a new code compression method where we merge the Huffman algorithm with the formation of patterns of blocks, which are found into the dictionary. We seek two consecutive blocks in two levels, one of them into compressed code and the other related to uncompressed code. We have used simulation with SimpleScalar and programs from MiBench. Our proposal has achieved a compression rate...
Provided unified learning platform, which is developed as a main goal of our ICT FP7 - Collaborative Project: Embedded Computer Engineering Learning Platform enables modular approach in education of computer engineers. It helps engineering education personnel to transform passive listener's students into active learners, thus stimulating students to actively participate in the learning process. Furthermore,...
Recently many developers are willing to replace RTOS from an ITRON specification OS to T-Kernel. Then they must port their programs from ITRON to T-Kernel. We have developed a wrapper named “I-right/TK” to make such porting easier. This paper describes technical points for such porting, and discusses advantages of I-right/TK, including evaluation of its performance.
With the wide application of embedded technology and its products, much attention has been turned to the development of program to improve the safety and reliability of embedded devices. In this paper, we present a construct program of embedded trusted computing environment based on QEMU virtual machine architecture. The proposed program, simulates functions of trusted cryptographic modules by software,...
Nowadays, Assistive Technology (AT) systems are closely tied to the devices that they control. Considering a smart environment where a person with a disability needs to interact with multiple devices, the user is forced to rely on AT software tools available on the each used platform. Therefore, computer skills are required to adjust any different computing environment configuration according to the...
Since there was no OpenGL implementation for FPGA-based embedded systems before this research, this paper presents a novel OpenGL implementation based on Mesa for an FPGA-based embedded system. This implementation includes the algorithms for Bézier-splines curves and surfaces that can support 3D rendering. In addition, compared with the environment of general-purpose computers, because of the limited...
This poster describes an academic development of an embedded system project named SETRAIF, which was performed during the 2nd half of 2012, by students and professors of computer engineering courses at the Brazilian Aeronautics Institute of Technology (Instituto Tecnologico de Aeronautica - ITA), combining the use of inter disciplinarity, Agile Methods, and Model Driven Development.
In this paper we present a vision of the sequence of three embedded systems design courses being taught for computer engineering technology students. The focus of these courses is to prepare strong students in both digital hardware design as well as embedded software design. The courses have been evolving from traditional delivery of the content to a highly interactive hands-on industry-like experience...
