Hardware Description

This paper presents the design and development of a technique for an Autonomous and Versatile mode Parking System (AVPS) that combines a various number of parking modes. The proposed approach is different from that of many developed parking systems. Previous research has focused on choosing only a parking lot starting from two parking modes (which are parallel and perpendicular). This research aims at developing a parking system that automatically chooses a parking lot starting from four parking modes. The automatic AVPS was proposed for the car-parking control problem, and could be potentially exploited for future vehicle generation. A specific mode can be easily computed using the proposed strategy. A variety of candidate modes could be generated using one developed real time VHDL (VHSIC Hardware Description Language) algorithm providing optimal solutions with performance measures. Based on simulation and experimental results, the AVPS is able to find and recognize in advance which parking mode to select. This combination describes full implementation on a mobile robot, such as a car, based on a specific FPGA (Field-Programmable Gate Array) card. To prove the effectiveness of the proposed innovation, an evaluation process comparing the proposed technique with existing techniques was conducted and outlined.

This study applies FPGA (Field Programmable Gate Arrays) technology to implement a motion controller for wafer-handling robot which has three-DOF (Degree of Freedom) motion. The proposed FPGA-based motion controller has two modules. The first module is Nios II processor which is used to realize the motion trajectory computation and the three-axis position/speed controllers. The second module is demonstrated to implement the three-axis current vector controllers by using FPGA hardware, and VHDL (VHSIC Hardware Description Language) is adopted to describe the controller behavior. Therefore, a fully digital motion controller for wafer-handling robot, such as one trajectory planning, three current vector controllers and three position/speed controllers are all implemented with an FPGA chip.

We present in the following work a hardware implementation of the two principal optical flow methods. The work is based on the methods developed by Lucas & Kanade, and Horn & Schunck. The implementation is made by using a field programmable gate array and Hardware Description Language. To achieve a successful implementation, the algorithms were optimized. The results show the optical flow as a vector field over one frame, which enable an easy detection of the movement. The results are compared to a software implementation to insure the success of the method. The implementation is a fast implementation capable of quickly overcoming a traditional implementation in software.

Alan Programlanabilir Kapı Dizileri (Field Programmable Gate Array-FPGA) programlanabilir sayısal bloklar ve bağlantılarını içeren cihazlar olup çok esnek ve hızlı çalışabilme özelliklerine sahiptir. Programlanabilen bu sayısal kapılar sayesinde karmaşık tasarımlar kolay bir şekilde geliştirilebilmektedir. FPGA’lar küçük boyutlarda olup bilgisayardan bağımsız mobil olarak ve bilgisayarlardan daha yüksek hızlarda çalışabilmektedirler. Veri madenciliğinin görevlerinden biri olan sınıflandırma probleminin çözümü için geliştirilmiş önemli makine öğrenimi algoritmalarından biri Destek Vektör Makineleri’ dir. Literatürde Destek Vektör Makineleri’ nin diğer birçok tekniğe göre daha başarılı sonuçlar verdiği kanıtlanmıştır. Tümör analizi, yüz tanıma, robotik göz oluşturma gibi konular, araştırmacıların görüntü işleme alanında yoğun olarak üzerinde çalıştıkları güncel, önemli ve zor problemlerden bazılarıdır. Bilgisayarda yapılan tümör analizinde, grafik ve resimlerin işlenmesinde yavaş işlem yapma ve aynı zamanda mobil olmama sorunlarından, FPGA donanımı ile görüntü işlemede bu sorunların üstesinden gelinmektedir. Bu çalışmada FPGA donanımında çalışan destek vektör makinası kullanılarak daha gerçekçi tümör analizi yapılarak tümörlü bölgelerin bulunması ve gerekli analiz sonuçlarının gösterilmesi amaçlanmaktadır. Böylece sağlık alanında da kullanılabilecek yararlı bir donanımın tasarımı gerçekleştirilecektir. Dolayısıyla gömülü sistemlerle anlatılan bu işlem süreçlerini gerçekleştiren çalışma sayısı çok az olduğundan çalışma özgün değer taşımaktadır. Buna ek olarak, FPGA’ ya özgü donanım tanımlama dillerinden biri olan Çok Yüksek Hızlı Tümleşik Devre Tanımlama Dili (Very High Speed Integrated Circuit  Hardware Description Language- VHDL) kullanılacaktır. Bölütleme sonucunun değerlendirilmesi için Uniformity Measure (UM) kullanılmıştır. UM değerlendirme sonucunun başarılı olduğu görülmüştür.

This paper proposes the design of 64-Quadrature Amplitude Modulation using the Very High Speed Integrated Circuit Hardware Description Language (VHDL) coding and XILINX SPARTAN Field Programmable Gate Array (FPGA) real-time implementation for validation. QAM is used in modern digital communication applications like set-top box, satellite TV, wireless and cellular technology etc. In this paper, 64-QAM is implemented and compared with three different XILINX SPARTAN FPGA devices say 3A DSP, 3E and 6E. The power, current and thermal parameters are performed and compared. The power consumed for the design of 64 QAM using the Xilinx SPARTAN 6E FPGA device is 0.014W and 15.9 C/W of Effective TJA for the XILINX SPARTAN 3A DSP FPGA. The device utilization of the 64-QAM design using the XILINX SPARTAN 3A DSP is low.

Verilog Hardware Description Language

The article proposes a variant of writing an algorithm for the operation of a device used in a field-programmable gate array on the example of random-access memory coding using the Verilog hardware description language. When performing the work, the Xilinx software is used, which allows working with the project at all stages of creating and describing the operation of the device logic. The practical significance of the work is the study and solution of the simplest problems in the development of modern radioelectronic rapid response devices in the Verilog hardware description language, such as coding a field-programmable gate array itself, writing test debugging code, setting input and output signals, sync pulse, reset and enable signals, describing the logic of devices such as counters, switches, registers and triggers, as well as simulating a finished project to assess the correct operation of the programmed device. This work can be used not only for teaching students of higher educational institutions in the field of development, debugging and coding of electronic and radio-electronic devices in terms of describing the algorithm of their work, but also for organizing laboratory work on courses of disciplines related to this topic, and for creating and designing real devices in production. The introduction and study of this programming language are conducted within the walls of one of the leading engineering universities of the Russian Federation — the Bauman Moscow State Technical University.
