Task of myriad estimator application for estimating distribution location parameter is considered. It is known that there is a great number of numerical algorithms for its calculation such as bracketed search, polynomial-root-finding, fixed point search, algorithm based on the Newton method, sequential algorithm, the method proposed by T. Pander and so on. This paper briefly describes aforementioned calculation algorithms and its properties. Algorithms' comparative analysis is performed with respect to both the mean square error of obtained estimates of location parameter and operating speed as well.

The Compressive Sensing (CS) method for reconstruction of musical signals is analyzed in this paper. CS is a new method for signal acquisition which has been developed in recent years. In the CS scenarios, it is possible to reconstruct the entire signal information from just a small set of randomly chosen measurements, using different minimization algorithms. Consequently, this method founds application in a large number of signal processing areas. The analyzed musical signals and the applied acquisition procedure, satisfy two important CS requirements. Namely, the observed signals have sparse representation in frequency domain, and the measurement procedure provides conservation of the main information about the signal, despite the reduction of the number of analyzed samples. Musical signals of different nature and complexity are observed in the paper. The efficiency of the CS reconstruction is analyzed for different number of available measurements. It will be shown that the minimal number of measurements required for successful signal reconstruction depends on the complexity of musical tones. Based on reconstruction error, the simple CS procedure for classification of two types of musical signals is presented. The reconstruction accuracy is measured by mean relative error between original and reconstructed signal, as well as perceptually — by listening both original and reconstructed signal.

Many applications in important domains, such as communication, multimedia, etc. show a significant data-level parallelism (DLP). A large part of the DLP is usually exploited through application vectorization and implementation of vector operations in processors executing the applications. While the amount of DLP varies between applications of the same domain or even within a single application, processor architectures usually support a single vector width. This may not be optimal and may cause a substantial energy and performance inefficiency. Therefore, an adequate more sophisticated exploitation of DLP is highly relevant. This paper studies the construction and exploitation of VLIW ASIPs with multiple vector widths.

The area coverage is a popular problem in wireless sensor networks and many attempts in the past several years have been made to provide an optimal solution to this particular type of problem. This paper presents a novel approach to solving the area coverage problem, namely the Harmony Search optimization algorithm. The Harmony Search algorithm is an optimization technique which is often used to solve NP-complete problems, i.e. problems which deterministic approaches to solve are not efficient for. The results have been compared to the Particle Swarm Optimization algorithm and have shown that Harmony Search gives better area coverage.

In this paper we propose a new, programmable, easy-tunable, current-mode general-purpose Biquad (C-GP-B), using second-generation current conveyors (CCIIs), based on the well-known direct form II, which, among other transfer functions, is also suitable to realize band-rejection (BR) or notch transfer function. It is convenient for elliptic transfer function realizations because it can realize finite transfer function zeroes. Since it has low sensitivity and grounded capacitors it is suitable for integrated circuit (IC) design. The new Biquad is then compared in sensitivity performance with other two CCII-based versions of biquadratic sections obtained by different approaches. Since all presented Biquads use CCIIs they operate in the current mode, and are therefore suitable to realize filter circuits operating at higher frequencies, consuming less power, and needing lower supply voltage. As an example, the design procedure, and the Monte Carlo sensitivity analysis using PSpice were performed for a fourth-order elliptic low-pass (LP) filter.

One of the perspective directions of embedded computer systems design is wide usage of configuration mechanisms on all levels of their architectural organization. This leads to increased complexity of toolchains and makes it necessary to consider the embedded systems and toolchains as a whole. In the article, we present three graphic notations to work with embedded systems in this way from different viewpoints: design process as a part of computational process; embedded systems as an hierarchy of processors (real and virtual); in system engineering style.

Systems composed by multiple physical domains (i.e. mechanical, biological, optical, fluidic, etc.) and usually controlled by an embedded HW/SW circuit cannot, up to date, be jointly simulated in order to correctly specify, dimension and verify these multi-domain microelectronics assisted systems at an early system level stage. This paper describes part of the work that it is being carrying out (under the CATRENE CA701 project) in order to define an open framework, based on SystemC-AMS, with the aim to extend this language to support multiple physical domains. The proposed extensions for being able to model a micro-fluidic system are going to be exposed. Two approaches have been selected: to model the fluid analytically based on the Poiseuille flow theory and to model the fluid numerically following the SPH (Smoothed Particle Hydrodynamics) approach. Both modeling techniques are, by now, encapsulated under the TDF (Timed Data Flow) MoC (Model of Computation) of SystemC-AMS.

Malicious hardware is a realistic threat. It can be possible to insert the malicious functionality on a device as deep as in the hardware design flow, long before manufacturing the silicon product.

Genetic algorithms are commonly used for automatically solving complex design problem because exploration using genetic algorithms can consistently deliver good results when the algorithm is given a long enough run-time. However, the exploration time for problems with huge design spaces can be very long, often making exploration using a genetic algorithm practically infeasible. In this work, we present a genetic algorithm for exploring the instruction-set architecture of VLIW ASIPs and demonstrate its effectiveness by comparing it to two heuristic algorithms. We present several optimizations to the genetic algorithm configuration, and demonstrate how caching of intermediate compilation and simulation results can reduce the exploration time by an order of magnitude.
