The methodology is an adaptation of an existing incremental power estimation method for Look Up Table based components. The models are based on the frequency, the activity rate and the input precision by using the Xpower tool with a free glitching. We have validated our approach by using the Euclidean distance computing application. The results show that the estimate is even closer to the real value when we use mathematical models of IPs with combination operators and the average accuracy of the model is higher and the maximum reached average error is equal to 3.14%. The power model is verified by on board measurement bench based on a Virtex2Pro FPGA real environment.","PeriodicalId":114829,"journal":{"name":"7th International Conference on Design & Technology of Integrated Systems in Nanoscale Era","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127241742","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}

Pulse mode is gaining support in the field of hardware Neural Networks thanks to its higher density of integration. However, the complexity of the activation functions presents a drawback for hardware implementation of Neural Networks and limits its area of application. In this context, the main idea is to apply a new kind of activation function, simply generated by the product of two sigmoidal functions, which are very simple and already implemented in previous work. Details of important aspects concerning the hardware implementation are given. To verify the performance and capacity of the proposed design, we apply it for approximation of image denoising function. The filtered results are verified in terms of the Peak Signal to Noise Ratio (PSNR). Experimental results reveal that the proposed PMNN filter has a greater ability to recover the informative pixel intensities from the infected image with a recovery of 7.5 dB for Gaussian noise and 5.3 dB for Speckle noise. Besides, such results demonstrate the performance and efficiency of our Neural filter when compared to other conventional filtering techniques. The designed network is implemented on a field-programmable gate array (FPGA) platform and synthesis results are presented and discussed.","PeriodicalId":114829,"journal":{"name":"7th International Conference on Design & Technology of Integrated Systems in Nanoscale Era","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122604986","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 technology that promises further increase of transistor density (in addition with heterogeneous integration, better performance and less power dissipation at a smaller footprint) is the three-dimensional stacked ICs (3D-SICs). Several stacking approaches are under development to manufacture such 3D-SICs. Wafer-to-Wafer (W2W) stacking seems the most favorable approach when high manufacturing throughput, thinned wafers and small die handling is required. However, efficient and optimal test approaches to satisfy the required quality are still subject to research. Each manufactured 3D-SIC undergoes a test and therefore optimizing test cost will have a large overall impact. This paper discusses test cost optimization for W2W 3D-SICs. It first introduces a framework covering different test flows for 3D W2W ICs. Test flows that include pre-bond tests can benefit from wafer matching; in wafer matching a software algorithm is used to increase the compound yield by stacking wafers with similar fault distributions. Subsequently, the paper proposes a cost model to evaluate and estimate the impact of test flows on the overall 3D-SIC cost. Our simulation results show that test flows with pre-bond testing in general significantly reduce the overall cost. These test flows benefit mostly from the yield increase due to wafer matching.","PeriodicalId":114829,"journal":{"name":"7th International Conference on Design & Technology of Integrated Systems in Nanoscale Era","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124879959","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}
