Opis:
Background : Due to the increasing complexity of embedded systems, system designers use higher levels of abstraction in order to model and analyse system performances. STARSoC (Synthesis Tool for Adaptive and Reconfigurable System-on-Chip) is a tool for hardware/software co-design and the synthesis of System-on-Chip (SoC) starting from a high level model using the StreamsC textual language. The process behaviour is described in the C syntax language, whereas the architecture is defined with a small set of annotation directives. Therefore, these specifications bring together a large number of details which increase their complexity. However, graphical modelling is better suited for visualizing system architecture. Objectives : In this paper, the authors propose a graphical modelling editor for STARSoC design tool which allows models to be constructed quickly and legibly. Its intent is to assist designers in building their models in terms of the UML Component-like Diagram, and in the automatic translation of the drawn model into StreamsC specification. Methods : To achieve this goal, the Model-Driven Engineering (MDE) approach and well-known frameworks and tools on the Eclipse platform were employed. Conclusion : Our results indicate that the use of the Model-Driven Engineering (MDE) approach reduces the complexity of embedded system design, and it is sufficiently flexible to incorporate new design needs.

Opis:
In this correspondence an efficient approach to structure of hardware accelerator for calculating the quotient of two complex-numbers with reduced number of underlying binary multipliers is presented. The fully parallel implementation of a complex-number division using the conventional approach to structure organization requires 4 multipliers, 3 adders, 2 squarers and 2 divider while the proposed structure requires only 3 multipliers, 6 adders, 2 squarers and 2 divider. Because the hardware complexity of a binary multiplier grows quadratically with operand size, and the hardware complexity of an binary adder increases linearly with operand size, then the complex-number divider structure containing as little as possible embedded multipliers is preferable.

Opis:
An application specific integrated design using Quadrature Linear Discriminant Analysis is proposed for automatic detection of normal and epilepsy seizure signals from EEG recordings in epilepsy patients. Five statistical parameters are extracted to form the feature vector for training of the classifier. The statistical parameters are Standardised Moment, Co-efficient of Variance, Range, Root Mean Square Value and Energy. The Intellectual Property Core performs the process of filtering, segmentation, extraction of statistical features and classification of epilepsy seizure and normal signals. The design is implemented in Zynq 7000 Zc706 SoC with average accuracy of 99%, Specificity of 100%, F1 score of 0.99, Sensitivity of 98% and Precision of 100 % with error rate of 0.0013/hr., which is approximately zero false detection.

This article presents a methodological proposal for implementing interval type-2 fuzzy processors over digital signal controller technology. We describe the main considerations that a practitioner or an engineer should follow when implementing an interval type-2 fuzzy system over an embedded processor. These considerations guide the implementation study of eight interval type-2 fuzzy processors, which are fully characterized and tested. Results show that by combining fast computing strategies and technologies like digital signal controllers, the inference time of an embedded type-2 fuzzy processor can be set to hundreds of microseconds.

Opis:
Mobile mini-robots are commonly used for research, education and popularization of science. Often, commercially available mini-robots don't quite fit the characteristics needed for a particular task, and are difficult to adapt since they have proprietary software and hardware. Moreover, they are often quite expensive. In this work we present a relatively low-cost, reconfigurable robot equipped with a wide variety of sensors and enough processing power to allow the on-board execution of intelligent algorithms. We present the complete hardware architecture, and a modularized software architecture that makes full use of hardware interruptions and software processes to have a perfectly timed control of the robot. All these characteristics make the new mobile mini robot ExaBot a very malleable, multi task mini-robot.

Opis:
This paper presents the algorithmic aspects of organization of a lowcomplexity fully parallel processor unit for constant matrix-vector products computing. To reduce the hardware complexity (number of twooperand multipliers), we exploit the Winograd’s inner product calculation approach. We show that by using this approach, the computational process of calculating the constant matrix-vector product can be structured so that it eventually requires fewer multipliers than the direct implementation of matrix-vector multiplication.
W pracy został przedstawiony sprzętowo-zorientowany algorytm wyznaczania iloczynu wektora przez macierz stałych. W odróżnieniu od implementacji naiwnego sposobu zrównoleglenia obliczeń wymagającego N2 układów mnożących proponowana równoległa struktura wymaga tylko N(M+1)/2 takich układów. A ponieważ układ mnożący pochłania znacznie więcej zasobów sprzętowych platformy implementacyjnej niż sumator, to minimalizacja liczby tych układów podczas projektowania dedykowanych układów obliczeniowych jest sprawą nadrzędną. Idea syntezy algorytmu oparta jest na wykorzystaniu do wyznaczania cząstkowych iloczynów skalarnych metody S. Winograda. Zaprezentowany w artykule algorytm może być z powodzeniem zastosowany do akceleracji obliczeń w podsystemach cyfrowego przetwarzania danych zrealizowanych na platformach FPGA oraz zaimplementowany w dowolnym środowisku sprzętowym, na przykład zrealizowana w postaci układu ASIC. W tym ostatnim przypadku niewątpliwym atutem wyróżniającym przedstawione rozwiązanie jest to, że zaprojektowany w ten sposób układ będzie zużywać mniej energii oraz wydzielać mniej ciepła.

Opis:
The Phase Locked Loop (PLL) has become an important part of electrical systems. When designing a PLL, an efficient and reliable simulation platform for system evaluation is needed. However, the closed loop simulation of a PLL is time consuming. To address this problem, in this paper, a new PLL model containing both digital and analog parts based on SystemC/SystemC-AMS (BETA version) is presented. Many imperfections such as Voltage Control Oscillator (VCO) noise or reference jitter are included in this model. By comparing with the Matlab model, the SystemC/SystemC-AMS model can dramatically reduce simulation time. Also, by comparing with Analog Devices ADI SimPLL simulation results, Cadence simulation results and real measurement results, the accuracy of the SystemC/SystemC-AMS model is demonstrated. The paper shows the feasibility of a unified design environment for mixed-signal modelling based on SystemC/SystemC-AMS in order to reduce the cost and design time of electrical systems.

Opis:
This paper presents a high-speed parallel 3x3 matrix multiplier structure. To reduce the hardware complexity of the multiplier structure, we propose to modify the Makarov's algorithm for 3?3 by 3?3 matrix multiplication. The process of matrix product calculation is successively decomposed so that a minimal set of multipliers and fewer adders are used to generate partial results which are combined to generate the final results. Thus, our proposed modification reduces the number of adders compared to the direct implementation of the Makarov's algorithm, and takes advantage of parallelism of calculation offered by field-programmable gate arrays (FPGA's).
W pracy została przedstawiona struktura jednostki procesorowej do wyznaczania iloczynu dwóch macierzy trzeciego stopnia. W odróżnieniu od implementacji naiwnego sposobu zrównoleglenia obliczeń wymagającego 27 układów mnożących proponowana równoległa struktura wymaga tylko 22 układa mnożących. A ponieważ układ mnożący pochłania znacznie więcej zasobów sprzętowych platformy implementacyjnej niż sumator, to minimalizacja układów mnożących przy projektowaniu mikroelektronicznych jednostek procesorowych jest sprawą nadrzędną. Zasada budowy proponowanej jednostki oparta jest na realizacji autorskiej modyfikacji metody Makarova, z tym, że implementacja naszej modyfikacji wymaga o 38 sumatorów mniej niż implementacja metody Makarova. Zaproponowana struktura może bycz z powodzeniem zastosowana do akceleracji obliczeń w podsystemach cyfrowego przetwarzania danych zrealizowanych na platformach FPGA oraz zaimplementowana w dowolnym środowisku sprzętowym, na przykład zrealizowana w postaci układu ASIC. W tym ostatnim przypadku niewątpliwym atutem wyróżniającym przedstawione rozwiązanie jest to, że zaprojektowany w ten sposób układ będzie zużywać mniej energii oraz wydzielać mniej ciepła.

This work present an efficient hardware architecture of Support Vector Machine (SVM) for the classification of Hyperspectral remotely sensed data using High Level Synthesis (HLS) method. The high classification time and power consumption in traditional classification of remotely sensed data is the main motivation for this work. Therefore presented work helps to classify the remotely sensed data in real-time and to take immediate action during the natural disaster. An embedded based SVM is designed and implemented on Zynq SoC for classification of hyperspectral images. The data set of remotely sensed data are tested on different platforms and the performance is compared with existing works. Novelty in our proposed work is extend the HLS based FPGA implantation to the onboard classification system in remote sensing. The experimental results for selected data set from different class shows that our architecture on Zynq 7000 implementation generates a delay of 11.26 μs and power consumption of 1.7 Watts, which is extremely better as compared to other Field Programmable Gate Array (FPGA) implementation using Hardware description Language (HDL) and Central Processing Unit (CPU) implementation.

The telemetry data are essential in evaluating the performance of aircraft and diagnosing its failures. This work combines the oversampling technology with the run-length encoding compression algorithm with an error factor to further enhance the compression performance of telemetry data in a multichannel acquisition system. Compression of telemetry data is carried out with the use of FPGAs. In the experiments there are used pulse signals and vibration signals. The proposed method is compared with two existing methods. The experimental results indicate that the compression ratio, precision, and distortion degree of the telemetry data are improved significantly compared with those obtained by the existing methods. The implementation and measurement of the proposed telemetry data compression method show its effectiveness when used in a high-precision high-capacity multichannel acquisition system.

Opis:
This paper presents a low multiplicative complexity fully parallel algorithm for multiplying two dual quaternions. The “pen-and-paper” multiplication of two dual quaternions requires 64 real multiplications and 56 real additions. More effective solutions still do not exist. We show how to compute a product of two dual quaternions with 24 real multiplications and 64 real additions. During synthesis of the discussed algorithm we use the fact that the product of two dual quaternions can be represented as a matrix–vector product. The matrix multiplicand that participates in the product calculating has unique structural properties that allow performing its advantageous factorization. Namely this factorization leads to significant reducing of the multiplicative complexity of dual quaternion multiplication. We show that by using this approach, the computational process of calculating dual quaternion product can be structured so that eventually requires only half the number of multipliers compared to the direct implementation of matrix-vector multiplication.
