Multirate filtering technique is widely used for meeting the sampling rates of different systems and it is a powerful technique in DSP which results in low-cost implementations of digital filters. Polyphase decomposition technique reduces the computational complexity by adopting parallelism in multirate digital filters. Power consumption is always a prime design constraint while implementing multirate...
In this paper, an overview of scheduling mechanisms constructed to enhance availability of services an embedded real-time system delivers is introduced along with the concept of a framework for comparison of the mechanisms. The framework expects that XML-based descriptions of the following parts of the system are available at its input: target device, operating system, application, scheduler and specification...
Ad-hoc networks allow nodes communication without an infrastructure, so they can be used in many environments. This lack of infrastructure introduces many security threats to the nodes in the network. Communication between nodes must be reliable, and protocols for MANETs need to make it possible. Due to the wireless channel and to the possible malicious behavior of nodes, it is necessary to introduce...
This paper discusses energy consumption reduction in Zigbee based networks. We introduce energy consumption benchmarking platform (ECBP) - a versatile data acquisition based energy consumption profiling system for WSNs. The ECBP can be utilized to find power intensive processes in a given system, discover energy consumption anomalies and wasted power, measure active duty and sleep cycles, measure...
The increasing trend in using mobile devices causes the power consumption to become the key aspect in modern digital systems design. The current flow for low-power design involves the use of some power-reduction technique at the RTL (Register Transfer Level) or lower levels. This paper describes an extension of current low-power design flow. It proposes the power-intent specification based on UPF...
This paper presents acSynth, an ArchC framework for energy characterization and simulation. Based on Tiwari's Method, a subject processor is characterized in an affordable time and the information is fed into acSynth to bring architecture level power analysis. The framework provides power reports and energy profiling. The experimental results show the characterization flow for the Plasma processor,...
Background location tracking is the key enabler for future generations of Location-based Services such as Geofencing, where the location of a user needs to be monitored continuously. Previous research has shown, that especially in the area of energy-efficient background tracking algorithms, huge potential still lays untapped. New algorithms can improve the energy- efficiency while retaining the required...
