A novel low-power and high-speed D flip-flop is presented in this letter. The flip-flop consists of a single low-power latch, which is controlled by a positive narrow pulse. Hence, fewer transistors are used and lower power consumption is achieved. HSPICE simulation results show that power dissipation of the proposed D flip-flop has been reduced up to 76%. The operating frequency of the flip-flop is also greatly increased.

One of the most promising applications of single-electronics is a single-electron memory chip. Such a chip would have orders of magnitude lower power consumption compared to state-of-the-art dynamic memories, and would allow integration densities beyond the tera bit chip.We studied various single-electron memory designs. Additionally we are proposing a new memory cell which we call the T-memory cell. This cell can be manufactured with state-of-the-art lithography, it operates at room temperature and shows a strong resistance against random background charge.

High-performance reconfigurable computing systems integrate reconfigurable technology in the computing architecture to improve performance. Besides performance, reconfigurable hardware devices also achieve lower power consumption compared to general-purpose processors. Better performance and lower power consumption could be achieved using application-specific integrated circuit (ASIC) technology. However, ASICs are not reconfigurable, turning them application specific. Reconfigurable logic becomes a major advantage when hardware flexibility permits to speed up whatever the application with the same hardware module. The first and most common devices utilized for reconfigurable computing are fine-grained FPGAs with a large hardware flexibility. To reduce the performance and area overhead associated with the reconfigurability, coarse-grained reconfigurable solutions has been proposed as a way to achieve better performance and lower power consumption. In this chapter, the authors provide a description of reconfigurable hardware for high-performance computing.

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.

In this work, the design of the diminished-1 modulo [Formula: see text] adders, subtractors and adders/subtractors are examined. Some of the existing modulo [Formula: see text] adders, subtractors and adder/subtractors are redesigned and improved. Compared to other existing implementations, the proposed subtractor and adder/subtractors offer reduced area complexity and lower power consumption, while operating at the same speed. All the considered architectures are modified parallel-prefix adders with fast input carry processing. The totally parallel-prefix and carry look ahead implementation of the proposed arithmetic units are also discussed.

Multiplier Circuit

Digital multiplier circuits are used in computers. A multiplier is an electronic circuit used in digital electronics to multiply two binary numbers. Multiplier circuits are used in ALU for binary multiplication of signed and unsigned numbers. The delay, area and power consumption are the 3 most important design specifications a chip designer has to consider. Delay of the circuit is directly proportional to the delay of a multiplier. Increased delay in the multiplier leads to higher delay in the circuit. Therefore research is carried out as to how to reduce the delay of the multiplier block so as to reduce the delay of whole circuit. The main purpose is to deal with high speed and lower power consumption even after decreasing the silicon area. This makes them well-suited for numerous complex and convenient VLSI circuit implementations. The fact however, remains that area and speed are two contradictory performance restrictions. Hence, increase in speed always results in the use of more and complex hardware. Different arithmetic techniques can be used to implement different multiplier circuits. The focus of this paper is to implement various multiplier circuit and compare them. The timing signals can be observed using software such as Modelsim and Xilinx.

Decomposition Scheme

In this paper, a novel decomposition approach and VLSI implementation of the chroma interpolator with great hardware reuse and no multipliers for H.264 encoders are proposed. First, the characteristic of the chroma interpolation is analyzed to obtain an optimized decomposition scheme, with which the chroma interpolation can be realized with arithmetic elements (AEs) which are comprised of only adders. Four types of AEs are developed and a pipelining hardware design is proposed to conduct the chroma interpolation with great hardware reuse. The proposed design was prototyped within a Xilinx Virtex6 XC6VLX240T FPGA with a clock frequency as high as 245 MHz. The proposed design was also synthesized with SMIC 130 nm CMOS technology with a clock frequency of 200 MHz, which could support a real-time HDTV application with less hardware cost and lower power consumption.

We have previously developed a microparticle sampling method in which electrowetting-actuated droplets sweep and pick up microparticles trapped on a perforated membrane. In this configuration, a critical issue is to increase the opening ratio (ratio of opening hole area to the total membrane area) in the perforated membrane as much as possible since the higher the opening ratio the lower power consumption in the process of air suction. In contrast, increasing the opening ratio hampers successful electrowetting operations of droplets and thus sampling of microparticles. In this study, we analytically investigate effects of the opening ratio on electrowetting operations. In particular, we are looking at the reversibility of electrowetting operation. Then, we fabricate testing devices to verify the analytical results in the range of the opening ratio up to about 90%. We will also discuss detailed challenging issues in microfabrication to reach such a high opening ratio.
