TL;DR: A genetic algorithm (GA) by implementing it in a reconfigurable field programmable gate array (FPGA) is described, which achieves a net child chromosome generation rate of one per clock cycle by pipelining the parent selection, crossover, mutation, and fitness evaluation functions.
Abstract: Accelerating a genetic algorithm (GA) by implementing it in a reconfigurable field programmable gate array (FPGA) is described. The implemented GA features: random parent selection, which conserves selection circuitry; a steady-state memory model, which conserves chip area; survival of fitter child chromosomes over their less-fit parent chromosomes, which promotes evolution. A net child chromosome generation rate of one per clock cycle is obtained by pipelining the parent selection, crossover, mutation, and fitness evaluation functions. Complex fitness functions can be further pipelined to maintain a high-speed clock cycle. Fitness functions with a pipeline initiation interval of greater than one can be plurally implemented to maintain a net evaluated-chromosome throughput of one per clock cycle. Two prototypes are described: The first prototype (c. 1996 technology) is a multiple-FPGA chip implementation, running at a 1 MHz clock rate, that solves a 94-row × 520-column set covering problem 2,200× faster than a 100 MHz workstation running the same algorithm in C. The second prototype (Xilinx XVC300) is a single-FPGA chip implementation, running at a 66 MHZ clock rate, that solves a 36-residue protein folding problem in a 2-d lattice 320× faster than a 366 MHz Pentium II. The current largest FPGA (Xilinx XCV3200E) has circuitry available for the implementation of 30 fitness function units which would yield an acceleration of 9,600× for the 36-residue protein folding problem.

06 Nov 2002TL;DR: In this paper, the authors have demonstrated high aspect ratio pattern fabrication as high as 6.0 with 200nm in line width using nano imprint lithography, but the mold is fabricated using thin Si substrate and anisotropic wet chemical etching.
Abstract: Nano imprint lithography is an attractive fine lithographic method to obtain nano patterns by using low cost process and materials., Various applications have been demonstrated to utilize this fine method. One of the advantages of nano imprint lithography is that a wet development process is not required, which sometimes causes sticking errors by surface tension during wet development process. On the other hand, there is no fear of such defects by imprint lithography because a resist is mechanically deformed and released. We have demonstrated high aspect ratio pattern fabrication as high as 6.0 with 200nm in line width. But the mold is fabricated using thin Si substrate and anisotropic wet chemical etching, which cannot fabricate voluntary patterns by crystalline axis dependence.

TL;DR: The major features of the proposed MC are block-partitioning prediction and the utilization of two time-differential reference frames, which improves the image quality around the objects' boundaries and consequently reduces prediction errors.
Abstract: Several studies on very low bit rate video coding have been reported. One of the major goals of the studies is to improve the coding performance, which gives better subjective and objective quality than conventional coding methods at the same bit rate. As the shape and structure of an object in a picture are arbitrary, the performance of traditional coding with block-based motion compensation (MC) is not satisfactory. We present advanced MC schemes for very low bit-rate video coding. The major features of the proposed MC are block-partitioning prediction and the utilization of two time-differential reference frames. This coding scheme improves the image quality around the objects' boundaries and consequently reduces prediction errors. It also works well in the case of object occlusions. The combination of the proposed MC and discrete cosine transformation (DCT) shows a better performance in several test sequences than full-spec H.263.

20 Apr 1999TL;DR: In this article, the authors propose to make it possible to utilize information service provided by a carrier without formally designated a standard protocol as a communication network by a plurality of terminals connecting to a called terminal unit.
Abstract: An object of the present invention is to make it possible
to utilize information service provided by a carrier without
designating a standard protocol as a communication network A
plurality of carriers provide information services to a
communication network to which a called terminal unit (10) is
connected through a communication line (20) At the time of
termination, a carrier control signal (6) transmitted from the
communication network includes a calling line number (6a) for
identifying an originator, carrier information (6b) for
identifying a carrier, and carrier service information (6c) for
identifying a service to be provided When a plurality of
terminals (15, 16) are connected to the called terminal unit
(10) as slave units, a function of inter-calling a
terminal-number provided by a carrier can be utilized Carrier
information identifying means (21) identifies a carrier on the
basis of the carrier information (6b), and carrier-service-information-identifying
means (22) controls a terminal
selecting circuit (14) on the basis of the carrier service
information (6c)
