a virtual hardware operating system for the xilinx xc6200
Field-Programmable Logic and Applications, 1996Co-Authors: Gordon J BrebnerAbstract:Computer operating systems relieve a user of the responsibility for managing physical resources, such as processors, memory and input/Output Devices. The evolution of FPGA technology means that a new resource is available — it is accessed like memory, but can behave like a flexible processor or input/Output Device. There is a role for an operating system in making this resource easy to use, by managing it on behalf of a user. This paper explores the issues involved in such management, in particular the problems involved in presenting a software-oriented user with a larger virtual hardware resource that is implemented using smaller physical FPGA hardware. A prototype operating system, that demonstrates operational solutions to the problems using the Xilinx XC6200 FPGA, is described.

Reducing Data-Memory Footprint of Multimedia Applications by Delay Redistribution
2007 44th ACM IEEE Design Automation Conference, 2007Co-Authors: Balaji Raman, Samarjit Chakraborty, Santanu DuttaAbstract:It is now common for multimedia applications to be partitioned and mapped onto multiple processing elements of a system-on-chip architecture. An important design constraint in such architectures is that the FIFO buffers connecting the processing elements (in a pipelined fashion) should not overflow and the playout buffer should never underflow. To meet these constraints, an usual design practice is to increase the initial playout delay after which the Output Device starts reading from the playout buffer. Although implementing this technique is straightforward and involves only the the computation of an appropriate playout delay, it suffers from the downside of a large playout buffer being required. In this paper, instead of associating the playout delay solely with the Output Device, we propose to redistribute this delay among all the processing elements running the various tasks of the multimedia application. We show that this delay redistribution technique can signficantly reduce (up to 70%) the total on-chip memory required.

HAI - Analysis of the Influence of Mothers' Traits and Behaviors on Children's Conversational Play with an Utterance-Output Device
Proceedings of the 7th International Conference on Human-Agent Interaction, 2019Co-Authors: Kazuhiro Mitsukuni, Jun Ichikawa, Yukari Hori, Yuta Ikeno, Leblanc Alexandre, Tetsukazu Kawamoto, Natsuki Oka, Yukiko NishizakiAbstract:Authors have conducted an observation experiment mainly on conversational play for creating the basic findings of childcare support by smart speakers. Our previous study analyzed children's attitudes and behaviors toward an utterance-Output Device during conversational play. In this experiment, the mother was beside her child, and the influence of the mother on the conversational play seemed to be great, but we have not been analyzed it yet. In this study, we analyzed the relationships between traits and behaviors of mothers, and children's conversational play. The results suggest that the more epistemic curiosity mothers are, the more children follow the instruction of an utterance-Output Device as third person, and that the more mothers prompt the conversational play toward their children, the less they react to phrases of the utterance-Output Device.

ICDL-EPIROB - Analysis of How Personality Traits Affect Children's Conversational Play with an Utterance-Output Device
2019 Joint IEEE 9th International Conference on Development and Learning and Epigenetic Robotics (ICDL-EpiRob), 2019Co-Authors: Jun Ichikawa, Kazuhiro Mitsukuni, Yukari Hori, Yuta Ikeno, Leblanc Alexandre, Tetsukazu Kawamoto, Yukiko Nishizaki, Natsuki OkaAbstract:Smart speakers (such as Amazon Echo and Google Home) are becoming a popular addition to homes, and it is expected that they will be used as parental support in the future. Previous studies have analyzed the history logs of the uses of their services and gathered impressions of them using questionnaire surveys and qualitative interviews. Details of how children interact with smart speakers have not been fully investigated. This study investigated children's interactions with an utterance-Output Device, such as a smart speaker, and focuses on the influences of the children's personality traits. The experiment was conducted in a realistic setting. The results indicate that the less nervous, more emotionally stable, or more adaptable to communication different from that at home children are, the more closely they engage in conversational play with an utterance-Output Device. The findings suggest that effective conversational play, which can lessen anxiety toward a novel utterance-Output Device, will be required in future interaction design.
