These works describe the implementation of a control unit which is an important part of Central Processing Unit (CPU) with the Field Programmable Gate Array (FPGA). In this work a frequency scaled and thermal aware energy-efficient control unit is designed with the help of 28 nanometer (nm) technology based FPGA. Frequency varies from 100MHz to 5GHz and the rise in frequency also gives rise in power consumption of control unit with FPGA. The thermal properties of FPGA also increase with increment in frequency. This whole experiment is done on Xilinx 14.1 ISE Design Suit and it is observed that lower the frequency, lower will be the power consumption of FPGA.

La capacidad de estimar funciones no lineales hace que las redes neuronales sean una de las herramientas más usadas para aplicar fusión sensorial, permitiendo combinar la salida de diferentes sensores para obtener información de la que a priori no se dispone. Por otra parte, la capacidad de procesamiento paralelo de las FPGAs (Field-Programmable Gate Array) las hace idóneas para implementar redes neuronales ubicuas, permitiendo inferir resultados más rápido que una CPU (Central Processing Unit) sin necesidad de una conexión activa a internet. De esta forma, en este artículo se propone un flujo de trabajo para diseñar, entrenar e implementar una red neuronal en una FPGA Xilinx PYNQ Z2 que use tipos de dato de punto fijo para hacer fusión sensorial. Dicho flujo de trabajo es probado mediante el desarrollo de una red neuronal que combine las salidas de una nariz artificial de 16 sensores para obtener una estimación de las concentraciones de CH4 y C2H4.

The issue of the energy shortage is affecting the entire planet. This is occurring because of massive population and industry growth around the world. As a result, the entire world is attempting to implement green networking systems and manufacture the power/energy efficient products. This research work discusses the green networking system technologies. This work introduces a power-efficient control unit (CU) design and implemented on the Zynq SoC (System on Chip) ultrascale field programmable gate array (FPGA). The VIVADO HLx Design Suite is used to simulate and analyze the CU model which is considered as one of the key components of central processing unit (CPU), used for data communication purposes. The CU is made suitable for the green communication by making it power-efficient. Therefore, the power consumption of the CU is analyzed for the various set frequency value ranging between 100 MHz and 5 GHz, and it is discovered that as the clock frequency rises up, the total power consumption also tends to get increased. The total power of the proposed model is reduced by 77.42%, 21.29%, and 17.93% from three models, respectively, being compared in the present paper. Final results shows that the CU is better suited to run at low frequencies to optimize power consumption.

Data acquisition is the most demanding application for the acquisition and monitoring of various sensor signals. The data received are processed in real-time environment. This paper proposes a novel Data Acquisition (DAQ) technique for better resource utilization with less power consumption. Present work has designed and compared advanced Quad Data Rate (QDR) technique with traditional Dual Data Rate (DDR) technique in terms of resource utilization and power consumption of Field Programmable Gate Array (FPGA) hardware. Xilinx ISE is used to verify results of FPGA resource utilization by QDR with state of the art DDR approach. The paper ratiocinates that QDR technique outperforms traditional DDR technique in terms of FPGA resource utilization.

Wallace Tree Multiplier

Nowadays, most of the application depends on arithmetic designs such as an adder, multiplier, divider, etc. Among that, multipliers are very essential for designing industrial applications such as Finite Impulse Response, Fast Fourier Transform, Discrete cosine transform, etc. In the conventional methods, different kind of multipliers such as array multiplier, booth multiplier, bough Wooley multiplier, etc. are used. These existing multipliers are occupied more area to operate. In this study, Wallace Tree Multiplier (WTM) is implemented to overcome this problem. Two kinds of multipliers have designed in this research work for comparison. At first, existing WTM is designed with normal full adders and half adders. Next, proposed WTM is designed using Ladner Fischer Adder (LFA) to improve the hardware utilization and reduce the power consumption. Field Programmable Gate Array (FPGA) performances such as slice Look Up Table (LUT), Slice Register, Bonded Input-Output Bios (IOB) and power consumption are evaluated. The proposed WTM-LFA architecture occupied 374 slice LUT, 193 slice register, 59 bonded IOB, and 26.31W power. These FPGA performances are improved compared to conventional multipliers such asModified Retiming Serial Multiplier (MRSM), Digit Based Montgomery Multiplier (DBMM), and Fast Parallel Decimal Multiplier (FPDM).

2D And 3D

2.5D/3D devices are the next major packaging technologies, driven by the need for more functionality, lower power consumption and smaller footprint. Many device manufacturers are devoting capital to develop their own processes and some are already shipping devices such as FPGA (Field Programmable Gate Array) on interposers. 3D packages often require hundreds of thousands of I/O per die. Micro Pillar bumps and C4 bumps are the main bump geometries used in 3D packages as their small pitch and size allow the required number of I/Os. Inspecting these bumps throughout the process is critical because failure after chip to chip or chip to wafer bonding is very costly. This paper describes the use of a camera and laser triangulation to provide complete 2D and 3D measurement and inspection capability.

This paper addresses the real-time optimization problem to find the most efficient and reliable message chain structure in data communications based on half-duplex command–response protocols such as MIL-STD-1553B communication systems. This paper proposes a real-time Monte Carlo optimization method implemented on field programmable gate arrays (FPGA) which can not only be conducted very quickly but also avoid the conflicts with other tasks on a central processing unit (CPU). Evaluation results showed that the proposed method can consistently find the optimal message chain structure within a quite small and deterministic time, which was much faster than the conventional Monte Carlo optimization method on a CPU.
