Физическая линия передачи данных представляет резервированный, гальваноразвязанный интерфейс с биполярным самосинхронизирующимся кодом Manchester-II.Актуальность разработки протокола обусловлена внедрением отечественной элементной базы, устойчивой к жестким воздействиям окружающей среды, в том числе и радиации, и степенью важности развития космической отрасли в целом, а также сфер, зависящих от нее.Рассмотрено назначение блока управления антенной. Обоснована необходимость разработки протокола информационно-управляющего сопряжения для блока управления. Проведен обзор научно-технической информации о составляющих данного протокола. Рассмотрены физический, канальный и информационный уровни разработанного протокола, а также представлена реализация канального и информационного уровня на языке Verilog HDL для ПЛИС.В программе Quartus-II разработан программный код, который реализует канальный и информационный уровни передачи данных на основе протокола информационно-управляющего сопряжения блока управления антенной с блоком-вычислителем. После чего из отдельных блоков кода формируется схемотехнический проект, где для блоков задаются входные и выходные сигналы.Моделирование протокола передачи данных проведено в среде для отладки ModelSim-Altera, а также на отработочной плате. Моделирование подтвердило правильность выбранных решений в процессе создания протокола передачи данных. На заданную команду получена верная ответная квитанция с двумя байтами контрольной суммы.

In this article, a design method of asynchronous FIFO memory based on FPGA is put forward. With FPGA as the core controller, We adopt Verilog HDL and top-down design method to build a top-level module design and also analyze the mark logic of asynchronous FIFO and the elimination of semi-stable state under Quartus II development platform. Besides, with the application of Gray code conversion technology, not only the reliable transmission of data is guaranteed but also design efficiency is improved. Through contrast experiment analysis and simulation test, the validity and reliability of asynchronous FIFO memory are verified, meeting the basic requirement that FIFO can hold more enough data without spillovers despite the fullness of data.

In this paper, an FPGA-based microwave oven controller design which can be implemented using Altera DE1 development board is presented. The motivation for this work is to explore FPGA for real time applications. First, a microwave oven controller design architecture that could fit into Altera DE1 board, utilizing on-board peripherals is developed. Then, using the proposed architecture, the design is implemented using Verilog HDL. The microwave oven functionalities are demonstrated using Altera DE1 development board by means of Quartus II 13.0 software. The testbenches are created and waveforms are generated using Modelsim 10.1d software. The simulation results for various cases have been presented and the results confirmed that all the basic functionalities of a practical microwave oven can be realized. The proposed FPGA based controller has a high potential for incorporation in microwave ovens.

In this paper, we put forward an innovation method of high-speed and real-time error diffusion, which is based on Floyd-Steinberg algorithm. The design introduces LUT(look up table) and pipeline technology instead of complex multiplication operations, which accesses to the memory frequently. The whole design uses Verilog HDL language to program and Quartus ii 8.0 to synthesize and layout. At the end of the paper, we use a 48 pixel as an example, then simulate and verify it on the Modesim, which can prove the correctness of the design. Compared with the standard Floyed-Steinberg algorithm, this design can reduce the computation complexity, use a smaller memory space to exchange lots of logic units and increase the throughput of the algorithm. Besides, it has the advantages of good reconfigurability, simple hardware structure and high real-time.

In this paper,we design a uniform circular array beamforming device of 16 yuan based on the least squares SLC-LSCMA algorithm (based on the linear subspace constrained least squares cma) high stability and rapid convergence for the foundation. The design of the complete beam-forming the SLC-LSCMA algorithm by plural, time-multiplier and accumulators, which uses less resources and faster than the traditional algorithm. The beamforming device uses hardware description language of Verilog HDL , and wires on the QUARTUS II 8.0. Finally the beamforming device is downloaded to the Alteras EP2C35F672C6, and its timing simulation can be run properly in the 50MHz clock frequency. This design can be widely used in mobile communication and satellite communications.

This research paper deals with design and implementation of low power 8-bit arithmetic logic units. The main part of power consumption is consumed in ALU in any processor. Therefore, reducing power dissipation in ALU should be requiring. The proposed technique disabled one of the main block of ALU using tri-state logic which is not necessary to use, except the required processes. In this work, the suggested design is realized by using ASIC methodologies. In order to implement the arithmetic and logic architectures, 130 nm standard cell libraries are used for ASIC execution. The architecture of the design has been created using Verilog HDL language. In addition, it is simulated using ModelSim-Altera 10.3c (Quartus II 14.1) tools. By using tri-state technique, dynamic power and total power are decreased
