In this paper the features of remote laboratories development are given. Investigation of tools and embodiments of the remote laboratories software was done. The development technology was chosen and approved based on requirement analysis for remote labs’. The different approaches to the organization of remote labs management system were considered. The practical results of the remote lab implementation...
The Embedded system is controlled with the combination of hardware and software. They are usually processed by a microprocessor / microcontroller that execute instructions which are present in ROM. The term "embedded" reflects to the fact that they are part of the system. Real-Time Operating System (RTOS) combines with two thoughts "real-time" and "operating system"....
Recently there has been a growing interest in models and methods targeted towards the design of video stream parallel processing, and the applications tend to be highly bursty and dependent parallel. As a result, the most existing models are not suitable for dealing with such system design. In this paper, we present an Event Count Model (ECM) to capturing the timing properties of video stream processing...
Energy-efficiency is becoming one of the most critical issues in embedded system design. In Network-on-Chip (NoC) based heterogeneous Multiprocessor Systems, the energy consumption is influenced dramatically by task allocation schemes. Although various approaches are proposed to allocate tasks in an energy-efficient way, existing work does not well explore the tradeoff between the two major power...
With the advance of semiconductor, multi-core architecture is inevitable in today's embedded system design. Nested loops are usually the most critical part in multimedia and high performance DSP (Digital Signal Processing) systems. Hence, maximizing loop parallelism is an important issue to improve the performance of a modern compiler. This paper studies how to maximize the system performance with...
Modern embedded multiprocessors are complex systems that often require years to design and verify. A significant factor is that engineers must allocate a disproportionate share of their effort to ensure that modern FPGA chips architecture behave correctly. This paper proposes a design and creation of embedded multiprocessors architecture system focusing on its design area and performance. Embedded...
This paper proposes an enhanced system-level synthesis flow for the design of reliable embedded systems, extending the classical process to introduce fault mitigation properties in the design under consideration. The strategy first explores the adoption of hardening techniques that, given the initial task graph and the user's reliability requirements, introduce redundancies and mapping constraints...
In recent years, we have witnessed the emerging trend in industrial informatics of joining web-services technologies in the embedded system's design. In one hand web-services turns lower the integration efforts of several technological entities through platform-independent interfaces. On the other hand it is well-known that embedded systems are everywhere, taking a great amount of research in design...
Energy consumption is a major issue in the design of embedded systems that are battery-driven. At the architectural level energy savings can be realized by a diversity of mechanisms. This paper presents the energy-savings mechanisms that are part of the time-triggered architecture (TTA). The paper starts with a general section on energy dissipation in VSLI circuits and an outline of the architectural...
This special session aims to introduce to the hardware/software codesign community challenges and opportunities in designing high performance computing (HPC) systems. Though embedded system design and HPC system design have traditionally been considered as two separate areas of research, they in fact share quite some common features, especially as CMOS devices continue along their scaling trends and...
The Embedded Systems Portability project investigates how to acquaint students in an engineering science curriculum with several important modern trends and practices in embedded system design. An overview of the program is given, and the specific objectives of several elective courses in electrical engineering are presented. The project also aims to provide a flexible but powerful controller for...
Low-power embedded system design has become extremely important in the most recent years. To fulfill system-level design requirements and time-to-market constraints, a power-driven methodology is essential during embedded system design. The aim of this paper is to introduce accurate and efficient power metrics included in a hardware/software (HW/SW) co-design environment to show the system-level partitioning...
A growing challenge in embedded system design is coping with increasing power densities resulting from packing more and more transistors onto a small die area, which in turn transform into thermal hotspots. In the current late silicon era silicon structures have become more susceptible to transient faults and aging effects resulting from these thermal hotspots. In this paper we present an agent-based...
Systematic architecture exploration from vast solution space is a complex problem in embedded system design. It is very difficult to explore a best architecture fast and accurately because accurate evaluation usually consumes significant amount of time for point in the solution space. In this paper, we propose fast and systematic architecture exploration method for address generation unit (AGU) based...
The article introduces the concept and principle of the timeout service, and elaborates on how to design it in the sequential operations and task operations during the programming for MCU (micro-controller unit). In virtue of interrupt mechanism, it needs just a few inner resources to realize. It can resolve the incidents that the program can't exit from the function modules because of the unsatisfied...
In this paper we assess the use of high performance computing in design space exploration of a complex highly parameterized very long instruction word based system-on-a-chip platform. Experiments show that the conventional belief of linear decrease in exploration time as the number of available processors increases is discredited starting from a relatively low number of processors mainly due to communication...
Coarse-grained reconfigurable architectures appear as a scalable solution to embedded system design, with a reduced reconfiguration time, memory footprint, as well as placement and routing complexity. To ensure high performance, data must be efficiently delivered to the reconfigurable matrix. For that, several architectures propose the use of fully interconnected local networks, as crossbar or large...
The development efficiency of embedded systems is highly pressured due to the pursuit of short time-to-market of embedded products. In traditional design flow, although software can be developed in parallel with the hardware platform, it can only be tested and verified after the platform is fabricated. ARMISS, an Instruction Set Simulator for the ARM architecture, is developed to enable early software...
This paper deals with a proposed strategy for embedded system design based on the design pattern approach and the concept of object-oriented, supported by unified modeling language (UML). It benefits from a set of methodologies as co-design approach design pattern approach, the language of unified models and abstraction of information. The new view in design strategy lays on a proposed design pattern...
With the improvement of SoC design flow, early system prototype is an efficient way in which designers can find function bugs and performance limitations.
