This paper presents the flexibility of technology FPGA in the implementation of automatic control systems. A digital structure at level hardware of a regulator of PI action was designed and built by the VHDL standard. Also, a Java graphical interface was developed for monitoring and control. Experiments were performed on a mechanism for position control consisting of DC motors with encoder, checking...
Advances in technology supported with higher communication bandwidth and data rate have led to optimum utilization of channel capacity for e-learning. Data rate to the extent of few gigabits per second provide easy access to students and professionals to learn from the best universities and eminent professors online without hassles and further evaluation with certification for the e-courses. The e-learning...
Java Card is a Java running environment specific for smart cards. In such low-end embedded systems, the execution time of the applications is an issue of first order. One of the components of the Java Card Virtual Machine (JCVM) playing an important role in the execution speed is the bytecode interpreter. In Java systems the main technique for speeding-up the interpreter execution is the Just-In-Time...
Small devices are running software ever more complex. In this scenario, which has been expanding with trends such Internet of Things (IoT) and Ubiquitous computing, becomes even more significant the process of debugging. The use of high-level language virtual machines (VM) on embedded systems can avoid issues on the portability, safety and memory management. However, it presents challenges for debugging...
Wireless Sensor Networks (WSNs) have played an important role in diverse domains. However, programming on WSN nodes are quite hard because currently there exist no standard software and hardware platforms in WSN. Thus it's essential to build a software infrastructure that can provide a decent development environment to the users. One sound choice to achieve this objective is to deploy embedded Java...
Modern, energy-efficient sensor nodes cover a wide variety of application scenarios. For a fast adapting of these devices to new requirements a concurrent development process of software and hardware extensions must be feasible. Here we present a Hybrid Simulation Environment (HSE) that combines a cycle accurate simulator for MSP microcontrollers written in Java and SystemC, which allows description...
Remote control and home automation terms are becoming very important nowadays. Sensors are everywhere: HVAC (Heating, Ventilation and Air Conditioning) systems, fridges, security cameras, hard disks inside servers, voltages, temperatures and fan speeds in modern computers are widespread. Access to these sensors, both physical and virtual (e.g. data retrieved from an operating system), is possible...
Virtual machines (VMs) play an important role in mainstream computing by enabling interoperability, security, and higher levels of abstraction. Their use in embedded computing systems is deterred primarily by the resource constraints of embedded microcontrollers. In this paper, we show how various optimizations can significantly decrease these overheads, making VMs viable as system software for even...
IEEE 1451 standard is intended to address the smart transducer interfacing problem in network environments. Usually, proprietary hardware and software are a very efficient solution for implementing the aforementioned normative, although they can become expensive and inflexible. In contrast, the use of open and standardized resources for implementing the IEEE 1451 smart transducer interface standards...
To overcome the disadvantages observed in the prevalent telerobotics systems, such as bulky, high power consumption and closed architectures, this paper introduces a novel design of embedded Telerobotics system using the technique integrating embedded Linux and computer network technology, which make the system be more compact and lower power consumption. As an open architecture, the hardware consists...
This paper presents a method for exploring communications capabilities of enhanced DS80C400 MAXIM/Dallas microcontroller, as a LAN server. Gravity mass lies in the implementation of several Java layers, working on server and client platforms. The LAN server is the MAXIM-Microcontroler System TINI, which itself is written in Java. Further in this paper are described results the experiment with TINI...
