The multiplication and summation functions are realized by using the PWM technique and simple mixed-mode circuits with good linearity and large dynamic range. From the measured results, the linearity of synapses versus input pulse widths can be almost kept under /spl plusmn/0.2%. Also the measured results on the simple Chinese word speech classification have successfully verified the function correctness and performance of the designed neural network.","PeriodicalId":20507,"journal":{"name":"Proceedings of APCCAS'96 - Asia Pacific Conference on Circuits and Systems","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1996-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74083460","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The system consists of a video conferencing system and application-specific programs. The video conferencing system provides two-way audio and video communications using MuX. Other application programs include shared electronic whiteboard, query control system, presentation manager and student database manager. Each of these applications provides useful tools that improve the quality of learning, while students are allowed to participate interactively. Design and implementation of the system is presented along with its communication characteristics.","PeriodicalId":20507,"journal":{"name":"Proceedings of APCCAS'96 - Asia Pacific Conference on Circuits and Systems","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1996-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75754699","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the NMRME scheme, motion vectors are estimated for low pass subimages of every layers, and all component subimages at the lowest layer by the block matching. At first the motion vectors are calculated for the low pass subimage at highest layer. Then, motion vectors at lower layers are refined using the motion information obtained at higher layers. Motion vectors for vertical, horizontal, and diagonal component subimages at lowest layers are refined using the motion vectors obtained at the low pass subimage of the same layer. Considering the simulation result, the PSNR is higher in the NMRME than that in MRME and FMRME. But, the bit rate is higher. Therefore, tile NMRME scheme is adequate for the application which requires a high PSNR.","PeriodicalId":20507,"journal":{"name":"Proceedings of APCCAS'96 - Asia Pacific Conference on Circuits and Systems","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1996-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77152378","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
