For an efficient power management scheme, an accurate power estimation is required. The power consumption of FPGAs differs depending on the input, and previous power estimation methods have limitations which make it difficult to predict the input patterns which affect the power consumption of FPGA. Therefore, we propose a simulator which is able to estimate the power in consideration of input data. It estimates the power consumption more accurately at a minute level. From the result of experiment, we identify that there is a great gap on power estimation between previous methods and the proposed one.","PeriodicalId":278207,"journal":{"name":"2016 International SoC Design Conference (ISOCC)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122131252","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}

A GNSS sensor is integrated with wireless sensor nodes to know its location distributed in geographically wide area, along with some energy harvesting device such as a solar cell. However, the GNSS sensor consumes relatively larger energy and requires longer sensing time for tracing satellites everytime, compared with other sensors. Although some power-down modes are used to reduce the power consumption, such as a \"sleep-mode\" and a \"standby-mode\", accumulation of running time and waiting time power is not small enough for a smaller capacity solar cell. \"Normally-off\" is a way of computing control which aggressively powers off components of computer systems. It uses power gating mechanisms and nonvolatile memories (NVMs) to turn off the power supply component by component. We applied the Normally-off control to a wireless sensor node to achieve extra low power for a smaller solar cell. This paper describes our Normally-off Computing application to the GNSS aware sensor nodes and evaluation of the performance under solar cell power supply.","PeriodicalId":278207,"journal":{"name":"2016 International SoC Design Conference (ISOCC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131293929","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}

And, for embedding in Field Programmable Gate Array (FPGA), we implement a dedicated hardware using 4006 lookup table (LUT) and 21KB sized internal memory.
