The method, which incorporates a new data compression algorithm, is capable of generating trajectory data at variable rates. In this paradigm, higher-order differences of a given trajectory (i.e. position) are first computed and thus the resulting data are compressed via the proposed technique. The generation of the commands is carried out according to the feedrate (i.e. the speed along the trajectory) set by the external logic dynamically. The paper discusses the implementation of the method on a Field Programmable Gate Array (FPGA). During implementation Very High Speed Integrated Circuit Hardware Description Language (VHDL) is used rather than using embedded processors on the FPGA chip. The performance of the method is assessed according to the resources used in the FPGA chip on the development board and these results are also compared with the same approach without an interpolator.","PeriodicalId":166416,"journal":{"name":"2010 8th Workshop on Intelligent Solutions in Embedded Systems","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133949322","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}

Its active area occupies only 0.04 mm2 and dissipates less than 22 mW. The sampling rate is higher than 500 MS/s and the achieved Signal to Noise and Distortion Ratio is higher than 40 dB. A voltage mode integer divider is used at the input of this Analogue/Digital Converter driving the two output Flash stages by its quotient and residue. The ultra low area and power is owed to the use of the integer divider at the input stage of the subrange converter and the employment of a “thermometer to binary encoder” instead of a full 4-bit Flash Analogue/Digital Converter for the generation of the 4 most significant bits. The calibration method employed for this Analogue/Digital Converter is based on the proper biasing of the resistor ladders used by the fine 4-bit Flash stage as well as on properly delaying and shifting of the divider signals that generate the residue.","PeriodicalId":166416,"journal":{"name":"2010 8th Workshop on Intelligent Solutions in Embedded Systems","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128983259","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 are used with a growing diversity of sensors in a plethora of applications, e.g., from Ambient Intelligence (AmI), Assisted Living (AAL) to agriculture. WSN based measurement and instrumentation systems commonly have to operate under tight power consumption constraints. In particular, WSN benefiting from micro-electro-mechanical-system (MEMS) miniaturization have a very limited power budget due to poor energy density of storage elements. While highly optimized microcontrollers are available by now, today's sensors and sensor electronics are the predominant cause of power consumption in WSN. The standard approach tries to minimize standby currents by low-power sensor, bridge, and amplifier design. In contrast, this paper investigates an approach of duty-cycled, reconfigurable sensor electronics for resistive bridge sensors, that seamlessly integrates into microcontroller' sleep modes. The circuit is optimized for the particular case of anisotropic magneto-resistive (AMR) sensor based localization in autonomous WSN. In a systematic analysis amplifier currents, slew-rate, and read-out or on-time Ton are optimized for minimum power consumption of a tri-axial AMR sensor. At the required read-out rates, e.g., one measurement per minute, energy consumption can be reduced to a factor 1.5·10−6 of the continuous operation. A reconfigurable chip in a standard 0.35 µm bulk CMOS technology is under preparation adding flexibility for different sensor types and calibration needs.","PeriodicalId":166416,"journal":{"name":"2010 8th Workshop on Intelligent Solutions in Embedded Systems","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125402502","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}

Abstraction is an important tool to manage complexity, because it allows to catch the essence of an object, giving less importance to other properties, avoiding premature introduction of implementation details. For this reason it is important to adopt a methodology that can lead to the desired functionality through the creation of high-level executable models that can be easily refined and adapted to the subsequent stages of hardware and software synthesis. In this paper, this methodology is applied in the development of an audio dynamic range compressor designed for the creation of an electronic musical keyboard.","PeriodicalId":166416,"journal":{"name":"2010 8th Workshop on Intelligent Solutions in Embedded Systems","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133162742","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}

This paper presents a new application domain independent approach for low capacity embedded systems to be part of applications and use cases based on semantic information interoperability.
