In this paper, we address the technology mapping for RAM-based FPGA. Functional decomposition is applied to decompose a large function into a set of smaller subfunctions such that each subfunction can be implemented using a single logic cell. Our system is mainly divided into two parts. The first part is designed specifically for totally symmetric functions. A Fast-Decompose algorithm based on weight dependency is proposed. The second part deals with general functions. We consider some techniques such as output partition, variable partition, don't care assignment and encoding to minimize the number of subfunctions derived. Using these techniques together, our tool, Fun-Map, improves the mapping results compared with other tools in terms of area and delay.

The study of very thin (<15 nm) YBa2Cu3O7−δ (YBCO) films is necessary both for investigating the nucleation and growth of films of this material and for achieving a better understanding of multilayer structures incorporating such thin YBCO regions. We have used transmission electron microscopy to examine ultra-thin films grown on MgO substrates by single-target, off-axis magnetron sputtering; details of the deposition process have been reported elsewhere. Briefly, polished MgO substrates were attached to a block placed at 90° to the sputtering target and heated to 650 °C. The sputtering was performed in 10 mtorr oxygen and 40 mtorr argon with an rf power of 125 watts. After deposition, the chamber was vented to 500 torr oxygen and allowed to cool to room temperature. Because of YBCO’s susceptibility to environmental degradation and oxygen loss, the technique of Xi, et al. was followed and a protective overlayer of amorphous YBCO was deposited on the just-grown films.

We examined whether Japanese people, 47 junior high school students, 49 undergraduates, and 52 older adults, possessed negative attitudes against blacks and the picture book Little Black Sambo. We assessed the implicit attitude toward the target word pairs, “black/white” and “Sambo/Heidi,” by utilizing a paper-based Implicit Association Test and found that both black and Sambo were associated more negatively than white and Heidi. However, the implicit attitudes assessed with a single-target IAT showed that 67 Japanese students showed positive implicit scores for blacks but with smaller valences. A post hoc analysis revealed that the reading experience of Little Black Sambo did not show a significant difference between the implicit attitudes of those who had and had not read the book.
