Hardware Description

Presently, cryptographic hash functions play a critical role in many applications, such as digital signature systems, security communications, protocols, and network security infrastructures. The new standard cryptographic hash function is Secure Hash Algorithm 3 (SHA-3), which is not vulnerable to attacks. The Keccak algorithm is the winner of the NIST competition for the adoption of the new standard SHA-3 hash algorithm. In this work, we present hardware throughput optimization techniques for the SHA-3 algorithm using the Very High Speed Integrated Circuit Hardware Description Language (VHDL) programming language for all output lengths in the Keccak hash function (224, 256, 384 and 512). Our experiments were performed with the Nios II processor on the FPGA Arria 10 GX (10AX115N2P45E1SG). We applied two architectures, one without custom instruction and one with floating point hardware 2. Finally, we compare the results with other existing similar designs and found that the proposed design with floating point 2 optimizes throughput (Gbps) compared to existing FPGA implementations.

In the process of complex product design, modeling in different fields and different disciplines is often involved. Designers often face many different development kits, platforms, and theories, among which significant differences exist. Especially in the process of algorithm-hardware implementation, it is necessary to have mastery of the knowledge including algorithm, hardware, circuit, and system engineering. In this paper, a modeling method of algorithm-hardware based on SysML is proposed to reduce the difficulty of algorithm-hardware modeling. By using the method, the designers who do not know the knowledge of hardware can also easily build the algorithm-hardware model. In this method, a method of graphical system modeling based on SysML is used, where the elements of the algorithm-hardware model are described by SysML graphical models. Then, the SysML graphical models are converted to Very-High-Speed Integrated Circuit Hardware Description Language. At last, a detecting algorithm of random number is complemented by the modeling method in this paper and the simulation results are presented at the conclusion.

In order to improve the automation level of the electrostatic precipitator, we used Very-High-Speed Integrated Circuit Hardware Description Language (VHDL) language to compile, emulate and optimize the control system of power source and vibration. In the design of Quartus platform, we used EP1C3T144C8 Field Programmable Gate Array (FPGA) chip to realize high voltage power supply, alarm and protection system. We also realized the compilation and simulation test of each part’s function of 20 s rapping and 40 min rapping cycle. At the same time, we recorded the waveform of simulation. It demonstrated that the validity of the relevant VHDL compilation. We used this method to achieve the optimization control of the electrostatic precipitator operating parameters. It has a strong practicability.

Abstract: In this paper, we present the design and implementation of the Radix 8 Booth Encoding Multiplier. There are many multipliers in existence in which Radix 8 Booth Encoding Multiplier offers a decrease in area and provides high speed due to its diminution in the number of partial products. This project is designed and simulated on Xilinx ISE 14.7 version software using VHDL (Very High Speed Integrated Circuit Hardware Description Language). Simulation results show area reduction by 33.4% and delay reduction by 45.9% as compared to the conventional method. Keywords: Booth Multiplier, Radix 8, Partial Product

And Performance

The work presented in this paper illuminates the design and simulation of a recursive or Infinite Impulse Response (IIR) filter. The proposed design algorithm employs the Genetic Algorithm to determine the filter coefficients to satisfy the required performance. The effectiveness of different platforms on filter design and performance has been studied in this paper. Three different platforms are considered to implement and verify the designed filter’s work through simulation. The first platform is the MATLAB/SIMULINK software package used to implement the Biquad form filter. This technique is the basis for the software implementation of the designed IIR filter. The HDL – Cosimulation technique is considered the second one; it inspired to take advantage of the existing tools in SIMULINK to convert the designed filter algorithm to the Very high-speed integrated circuit Hardware Description Language (VHDL) format. The System Generator is employed as the third technique, in which the designed filter is implemented as a hardware structure based on basic unit blocks provided by Xilinx System Generator. This technique facilitates the implementation of the designed filter in the FPGA target device. Simulation results show that the performance of the designed filter is remarkably reliable even with severe noise levels.

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. Anahtar Kelimeler: Alan Programlanabilir Kapı Dizileri, FPGA, çok yüksek hızlı tümleşik devre tanımlama dili, vhdl, segmentasyon, destek vektör makinesi
