This idea is based on a multiple (in practice double) accumulator model, which is used in order to obtain high accuracy in a series of floating-point additions. The goal is to introduce a possibility of reducing the power consumption without reducing the functionality. In the case of low power, instead of decreasing the performance of the system or shutting down the system, as it is done in other approaches, in our concept merely the accuracy of the floating point accumulation is reduced. Therefore although the quality of service is reduced, the performance is not.","PeriodicalId":310187,"journal":{"name":"2007 14th International Conference on Mixed Design of Integrated Circuits and Systems","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133811080","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}

The paper presents parameter extraction guidelines and modelling using EKV3 for TOSHIBA's 90 nm RF-CMOS technology covering DC, CV and RF (S-parameter) and temperature scalability. RF verification was done by the use of multi-finger MOSFETs with many variations of gate length, width of unit fingers and number of fingers. A scalable RF model was successfully created. Extraction of RF parasitics and their scaling with RF layout is investigated. The EKV3 model successfully predicted high-frequency behaviour of 90 nm CMOS up to 20 GHz over a wide range of bias conditions.","PeriodicalId":310187,"journal":{"name":"2007 14th International Conference on Mixed Design of Integrated Circuits and Systems","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123897302","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 DTL are interesting to use for either matching the circuits or for realizing small resonators in filters or oscillators. One very interesting aspect is the tunability of such a transmission line. Tunability means the ability to tune the electrical length and the characteristic impedance by applying appropriate voltage. In this paper, we introduce a new method to realize the tunability of these transmission lines thru magnetic coupling. This tunable Periodical DTL (PDTL) provides highly interesting applications for silicon MMICs.","PeriodicalId":310187,"journal":{"name":"2007 14th International Conference on Mixed Design of Integrated Circuits and Systems","volume":"109 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116820237","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}

The presented supervisors make decisions on the basis of current chip temperature; future, current and previous power dissipations. They consist in cooperation with operating system and they are dedicated to high efficiency systems. The proposed supervisors can be implemented in both software and hardware, e.g. as neural network. Not only performance gain but also energy profit can be made in systems that use these supervisors. Simulations results of considered cases show that theoretical improvement of the ideal supervisor is in the range of 7.38 to 16.17% for performance and of 2.47 to 9.88% for energy. The profit of the real supervise method depends on the complexity of supervisor.","PeriodicalId":310187,"journal":{"name":"2007 14th International Conference on Mixed Design of Integrated Circuits and Systems","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125939757","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}

Design patterns, intended for simplifying the reuse process, are design experiences that worked well in the past and documented to be reused in the future. In this paper, a design pattern named NnEP (Neural-network-based Embedded systems design Pattern) is introduced for employing neural networks, common bio-inspired solutions, in SoC-based embedded systems. This pattern is based on NnSP IP suite, a stream processing core and its tool chain, NnSP Builder and Stream Compiler. NnEP is introduced for enhancing and automating reuse in design of intelligent SoC's requiring high-speed parallel computations specially those based on neural networks. The NnEP pattern consists of the semi-automated steps, extracted from design experiences, a designer takes using the provided software suite to realize a NN application in an intelligent SoC. This includes the application analysis and pre-processing procedure, building the best-match IP core with the application, and finally compiling the intended NN application on the target IP core. On the other hand, ASIC 0.18 mum implementation results of NnSP soft core show that the core can achieve the speed of 51.2 GOPS, 25.6 GMAC/s. This throughput is comparable with the existing parallel solutions and higher in an order of magnitude from common general-purpose-processor-based solutions. This high throughput in conjunction with the inherent reusable architecture of NnSP, makes NnEP a powerful design pattern for cutting-edge neural-network-based embedded applications such as pattern recognition which is elaborated as a case study in the proposed design pattern.","PeriodicalId":310187,"journal":{"name":"2007 14th International Conference on Mixed Design of Integrated Circuits and Systems","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134115980","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}
