Their use as sensors is enabled due to their well-defined physical properties such as reflectance/ transmittance, superior levels of sensitivity resulting in precise detection limits. In this paper, we propose an ultracompact RI (refractive index) sensor based on single line photonic crystal waveguide structure. The properties of the sensor are simulated using the finite-difference time-domain (FDTD) method. The transmission spectrums of the sensor with different ambient refractive indices are calculated. The calculation results show that a change in ambient RI is apparent; the sensitivity of the sensor is achieved. The radius of the air holes localized at each side of the line defect is optimized to realize high sensitivity, wide measurement range and improved transmission. Development of sensor designs that enhance sensitivity is especially important because it allows detection of lower concentrations of analytes. For instance, refractive index (RI) sensing techniques detect an analyte by a local refractive index shift.","PeriodicalId":125634,"journal":{"name":"2011 Saudi International Electronics, Communications and Photonics Conference (SIECPC)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129605490","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}

Intra-prediction is one of the top 3 compute-intensive processing functions in the H.264/AVC baseline decoder [6] and, therefore, consumes significant number of compute cycles a processor. In this paper, we propose a configurable, high-throughput, and area-efficient hardware design for the intra-prediction unit. The intra-prediction algorithm is optimized to significantly reduce the redundancy in addition operations (e.g., 27% reduction when compared with state-of-the-art in literature [12]). The area requirement for our hardware implementation of the optimized intra-prediction algorithm is further reduced by employing a configurable design to reuse data paths for mutually exclusive processing scenarios. The proposed design is described in VHDL and synthesized under 0.18μm CMOS standard cell technology. While working at a clock frequency of 150 MHz, it can easily meet the throughput requirement of HDTV resolutions and consumes only 21K gates.","PeriodicalId":125634,"journal":{"name":"2011 Saudi International Electronics, Communications and Photonics Conference (SIECPC)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115144014","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}

Not only would every circuit be running on its own clock, but the interconnection network is fully synchronous and runs at an unrelated clock of its own. With relatively low gate count, the proposed FIFO allows communicating circuits to put/get data at their respective frequencies (1 datum/clock cycle) till it gets filled then the rates converge to the lower frequency. The maximum initial latency is 3 cycles of the consumer's clock. Several manifestations of the proposed FIFO have been developed for different design cases including data width mismatch between producer and consumer. The operation of different FIFOs has been verified using gate-level simulations for several ratios of clock frequencies. An 8-cell FIFO has been designed at the transistor-level and Spice simulations using a 0.13 μm, 1.2V technology has been carried out. It shows proper operation at producer and consumer clock frequencies of 2GHz and 3.125GHz, respectively, with a data transfer rate of more than 2Giga datum/second and an average power of 721 μW.","PeriodicalId":125634,"journal":{"name":"2011 Saudi International Electronics, Communications and Photonics Conference (SIECPC)","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114718932","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}
