The Grünwald-Letnikov and Caputo definitions are realized for different fractional orders. The realization is based on non-uniform segmentation algorithm with a variable lookup table. A generic implementation for Grünwald-Letnikov is proposed and a 32 bit Fixed Point Booth multiplier radix-4 is used for Caputo implementation. Carry look-ahead adder, multi-operand adder and booth multiplier are used to improve the performance and other techniques for area and delay minimization have been employed. A comparison between the two presented architectures is introduced. The proposed designs have been simulated using Xilinx ISE and realized on FPGA Xilinx virtex-5 XC5VLX50T. The total area of 2515 look up tables is achieved for Caputo implementation, and maximum frequency of 54.11 MHz and 1498 slices are achieved for Grünwald-Letnikov architecture.","PeriodicalId":202381,"journal":{"name":"2017 6th International Conference on Modern Circuits and Systems Technologies (MOCAST)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134363732","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 implementations demand expensive, heavy and not easily deployed equipment, while in many cases cannot provide a sufficient communication range. The current work proposes and demonstrates a lightweight and low-cost Arduino-based telecommunication subsystem that is capable of sending control commands to the UAV based on GSM or GPRS the most widely deployed cellular networks standard. During field trials control commands successfully transferred from a mobile phone as well as a laptop to the UAV autopilot, with an average time of 2.6 sec and 0.5 sec respectively. The proposed subsystem can be embedded independently or coexist with other control systems, contributing to a ubiquitous UAVs management system.","PeriodicalId":202381,"journal":{"name":"2017 6th International Conference on Modern Circuits and Systems Technologies (MOCAST)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134412002","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}

Several techniques are incorporated in order to achieve higher performance. The operations are fused by keeping the intermediate variables in Carry-Save format. Besides of the conventional, the Gauss complex multiplication algorithm is also explored. Considered that the twiddle factors cosϕ, sinϕ used in FFT algorithm are constant numbers, we apply to them a special NR4SD encoding scheme with the following sets of digit values: {−2, −1, 0, +1}. Finally, to increase the operation speed, one level of pipelining is introduced in all designs. We implement four designs: one conventional and three new Butterfly Units. In all cases, the proposed three schemes are superior in terms of operation speed, area and power, compared to the conventional.","PeriodicalId":202381,"journal":{"name":"2017 6th International Conference on Modern Circuits and Systems Technologies (MOCAST)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128486687","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}

They take into account current and future quantization errors improving upon the stability and noise shaping characteristics of conventional 1-bit ΣΔ modulators. The MSLA modulator system is found to be equivalent to a number of parallel conventional ΣΔ modulators sharing a multi-input 1-bit quantizer. The number of look-ahead steps along with other design parameters enable fine-tuning of performance vs. hardware complexity according to the application. The performance of MSLA modulators for various design parameter values is investigated, highlighting their advantages in a multitude of applications like digital transmitters, class-D power amplifiers and DACs.","PeriodicalId":202381,"journal":{"name":"2017 6th International Conference on Modern Circuits and Systems Technologies (MOCAST)","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116056502","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}

For this purpose, the project provides to students, researchers, as well as to citizens or even companies, with a framework and a digital platform which gives open access to a range of geodata, i.e. Earth Observation data, but also computing and visualization tools. By this way, it is expected that the participants can work in an open co-working space, where they can interact with each other. Additionally, the participants will be assisted to assess the business aspects of any potential idea. The outcome of such an activity is the increase of possibility for participants to find a revolutionary concept, which can result to new and sustainable applications and/or services. Moreover the target group exceeds the usual Earth Observation professionals, and focuses also in professionals of other disciplines, where the use of Earth Observation data can create novel technologies.","PeriodicalId":202381,"journal":{"name":"2017 6th International Conference on Modern Circuits and Systems Technologies (MOCAST)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125219562","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}
