The work in this paper analyzes the delay of multi-wall carbon nanotube (MWCNT) based interconnect systems at the system level by implementing a four-bit array multiplier using MWCNT based interconnects. The layout of the multiplier is drawn using MWCNT based interconnects and delay has been analyzed and compared with that of the traditional copper based interconnects. It has been observed that MWCNT based design has 3.4% less delay in the critical path as compared to the copper based design. The paper also describes a methodology of modeling and analyzing a system designed with MWCNT interconnects, using the conventional chip design flow and tools.","PeriodicalId":276803,"journal":{"name":"2012 International Symposium on Electronic System Design (ISED)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117032022","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}

End to end internet connectivity is provided by using 6LoWPAN based wireless network that uses the 802.15.4 radio. A service oriented architecture (SOA) [1] is implemented to extract meaningful information and present it in an easy-to-understand form to the end-user instead of raw data made available by sensors. A central electronic database and health care management software are developed. Vital health parameters are measured and stored periodically in the database. Further, support for real-time measurement of health parameters is provided through a web based GUI. The system has been implemented completely and demonstrated with multiple users and multiple WEIDs.","PeriodicalId":276803,"journal":{"name":"2012 International Symposium on Electronic System Design (ISED)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131277527","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}

One of the key aspect of the cognitive radio is the optimal channel selection. The cognitive radio system selects a licensed band which has acceptable availability and also satisfies the system needs in terms of bandwidth and power constraints. To this end we propose an energy aware spectrum decision framework for cognitive radio network (ESDF-CR), which guarantees a certain level of QoS to the system running on low power, by selecting those channels which require lesser power for transmission. Channel selection and packet admission control techniques have been proposed to realize the spectrum decision framework. A comparison is done with random channel selection scheme to show the effectiveness of the proposed framework.","PeriodicalId":276803,"journal":{"name":"2012 International Symposium on Electronic System Design (ISED)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121316429","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}

These tiny chips can electrically control the dynamics of nanoliter volume of discrete fluid droplets on an electrode array with desired actuation patterns. One important step in biochemical sample preparation is dilution, where the objective is to prepare a fluid with a desired concentration factor. Bioassays implemented on DMF biochips may require several different concentration values of the same sample. In this paper, we propose a scheme in which a set of different target droplets (target concentration values ranged between 0% and 100%) can be produced using 0% concentration (buffer solution) and 100% concentration (sample/reagent), with an error bounded above by 1/2^(n+1) where concentration values are rounded-off by an n-bit binary fraction. Simulation results show that significant amount of savings in the number of mix-split steps and waste droplets can be achieved in comparison with the repeated use of existing single target based methods for generating multiple concentration factors.","PeriodicalId":276803,"journal":{"name":"2012 International Symposium on Electronic System Design (ISED)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116776135","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}

Traditionally branch-and-bound has been a popular choice for determining the pareto-optimal frontier with respect to area and power under certain user constraints. In this paper we explore the scope of parallelism within the branch-and-bound(B/B) algorithm for control and data-flow intensive circuits in order to address the scalability issue. The scheduling also aims at maximum conditional and unconditional resource sharing and is able to attain sufficient area and power gains for complex benchmarks under strict and relaxed timing constraints. Experimental results reveals that the distributed framework is able to parallelize the search space uniformly and is able to achieve promising speedup compared to the serial B/B counterpart.","PeriodicalId":276803,"journal":{"name":"2012 International Symposium on Electronic System Design (ISED)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114178541","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 this paper, a generic high-speed Network Interface for Network on Chip using Ping Pong Buffers is proposed in order to ensure the seamless high throughput between the router and processing core. The proposed scheme uses simple control logic to handle the read and write operations simultaneously in the memory modules. This proposed method is analyzed with the existing Asynchronous First in First Out (FIFO) based NIs with different encoding schemes like One-Hot encoding and Johnson encoding. The optimal depth of the asynchronous FIFOs is calculated based on router frequency, processing element frequency, packet size and flit size at router and processing element using Practical Extraction and Report Language (PERL) and the required Register Transfer Level (RTL) Verilog Hardware Description Language (HDL) and timing constrain is created by Perl scripting itself. The NI is implemented using the asynchronous FIFOs and ping pong - double buffering scheme using Altera Stratix III FPGA. The synthesis results show that the proposed architecture enhances the speed of NI by 30 % when memory depth is 8 and enhances speed by 11% when memory depth is 256.","PeriodicalId":276803,"journal":{"name":"2012 International Symposium on Electronic System Design (ISED)","volume":"138 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114488126","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}
