This paper presents a coprocessor design that performs task scheduling for soft real-time systems. The proposed solution is based on the Guaranteed Earliest Deadline (GED) algorithm. Thanks to hardware implementation of the scheduler, the scheduler operations are always performed in two clock cycles regardless of the actual number of tasks and the maximum number of tasks in the system. Through synthesis results, two versions of the scheduler were compared: an existing EDF based scheduler and the proposed GED based scheduler. Both schedulers were verified using simplified version of Universal Verification Methodology (UVM) and applying millions of instructions with randomly generated deadline values. The FPGA resource costs have been evaluated by synthesis into Intel FPGA Cyclone V.

Deep learning models are known for being large and computationally expensive. It is a challenge to fit these models into edge devices which usually have frugal memory. A striking feature about neural networks is their enormous size. Embedded devices in edge computing scenario typically cannot handle large neural networks. We present two models of Convolutional Neural Networks (VGG16 type), with a modification in the prediction layer, potentially suitable for edge computing devices. Both networks have been designed for the classification of a human face by gender and age. The first one (VGG16/10) considers gender and age as two related characteristics and the final neurons have been conceived to hold these aspects together at the same time. The second one (VGG16/8+1) in the prediction layer has got a neuron for the prediction of gender and another eight for the prediction of age (according to the Adience benchmark). Such networks have been conceived to provide simultaneously information on both the gender and age of the person identified in the image, without the need to build two dedicated networks. The aim is to develop a solution that can be suitable in edge-computing scenario.

Spiral computed tomography (SCT) is the most accessible and informative imaging method. Medical specialists face a number of difficulties with searching of CT-images. The goal of our study was to optimize interpretation of the data of radiological methods used for assessment of the paranasal sinuses (PNSs) with estimation of measurement uncertainty. The results of this study allow us to objectively assess the condition of the bone tissue and increase the efficiency of SCT examination of the PNSs, obtained taking into account both the minimum and maximum bone thickness, giving a possibility to predict the course of pathological processes in the PNSs, depending on their anatomical features. After studies, data were obtained to optimize the assessment of morphological parameters of the bone tissue of the paranasal sinuses (bone thickness and density). Potential fluctuations have been identified that should be considered when interpreting the results of calculating indices of PNS bone thickness and density.

This paper proposes a medical information system, including a portable cardioanalyzer combined with an automated workplace of a cardiologist by the use of multi-agent technology. This system allows you to monitor the state of the heart in conditions of free activity of the patient, to identify quickly responding to critical heart conditions. Distinctive features of the proposed portable cardioanalyzer are the ability to determine the critical state of the patient's heart in real time based on patent-protected methods of non-invasive cardiac diagnosis and automatically call the ambulance service for the patient, if such a heart condition is revealed.

The article proposes an algorithm for reducing the resolution of reference depth maps (Ground Truth). The evaluating method is presented as well as a comparison of error values resulting from the reference depth map size reduction to various scaling algorithms. The aim of the work is to evaluate the accuracy of scaling depth maps by the proposed algorithm. The need for scaling arises in the tasks of reducing existing different test data sets to uniform parameters of a stereo system, one of which is sensor resolution. A generic data set with the same parameters is required for designing more accurate hybrid stereo vision algorithms with elements of artificial intelligence.

Before starting a new project or repairing an existed project, embedded system developers face to the selection problem between a huge amount of different tools (e.g., development methods, architectural styles or programming languages). Because of the problem complexity usually, a developer makes a decision based on fashion or last experience unless real project needs. That approach may significantly reduce a development efficient or ruin the project. In the article, the authors analyzed the selection problem for architectural design tools and purposed a method of comparative analysis based on criteria with partially ordered estimates. The method application demonstrated on comparing of architectural style for multilevel embedded system design.

A numerical method for determining the signal-to-noise ratio (SNR) in electrocardiograms (ECG), distorted by various types of additive noise, is proposed. It is based on the calculation of the compression ratio (CRn) of an ECG fragment of 10 seconds duration. The functional dependences of SNR on CRn for ECG distorted by electrode motion, muscle artefacts and mixed noise, were found, and they are exponential. The values of root mean square error (RMSE) for such dependencies were 4.24 dB, 3.57 dB и 3.33 dB accordingly for SNR in range −10…45 dB. It is proved that the inclusion of heart rate (HR) in the model reduces the error by 0.6-0.8 dB. The present approach is based on the standard library zlib and is recommended for use in portative mobile systems.
