difference in the synchronous frequency of video signal among PCs will become the key which recognizes the target. In the
experiment (2), we succeeded from about 4 meters away place with frequency which is inside of VCCI regulations. In the
experiment (3), we succeeded from about 30 meters away place, and we found that the position relation between a probe and
AC adapter is dependent on results.

Security Requirements are varied with rapid growth of Internet and mobile network in digitization progress of
information. The necessity for reexamination of the security technological strategy is increasing. For example, the systematic
security countermeasures which can prove having dealt with information appropriately are required in addition to direct
security countermeasure such as encryption and access control. The problem of digital evidence occurs as a view which takes
the lead for that. NICT started a research project ‘research and development about next-generation evidence based
technologies’ in 2001, and Hitachi tackled this. This paper reports overview of results of the research project and related topics
which contain hysteresis signature for long-term documents and its verification technologies.

We show and evaluate 2-kinds of systolic array type convolvers. One of them is the constant weight length (W-kind)
convolver, and the other is the constant output length (R-kind) convolver. In W-kind, 3-types are discussed, and in R-kind
3-types are also described. In the last section, Extensions to 2-D convolver from 1-D convolvers are shown.

Data Path Synthesis From Behavioral Descriptions: An Algorithmic Approach
Devadas, Srinivas; Newton, A. Richard; 1987 IEEE International Symposium on Circuits and Systems, Volume 2; 1987,
pp. 398-401; In English; See also 20060002103; Copyright; Avail.: Other Sources
This paper outlines our approach to data path synthesis from algorithmic or behavioral descriptions. Our approach
involves three steps. First, a skeleton data path is synthesized from the input data flow specification using powerful algorithms
for resource allocation and partitioning. This skeleton data path is pipelined using pipeline scheduling algorithms and
simultaneously a high level timing analysis is performed. Lastly, control is synthesized as a by-product of the data path
synthesis process. Unlike previous approaches to data path synthesis, the algorithms used in the synthesis steps, extensively
modify the input program while performing global optimizations on the data flow graphs, simultaneously address all aspects
of the allocation process while efficiently exploring tradeoffs in the design space.
