However, efficiently utilizing these resources requires hardware designers and complex computer aided design tools. The paper describes several multi-processor architectures implemented on an FPGA, including a 64-way single interface multiple data (SIMD) and a variable size very long instruction word (VLIW) architecture. The design and synthesis of the target architectures are presented and compared for scalability and achieving parallelism. The performance and chip utilization of a shared register file is examined for different numbers of VLIW processing elements. The associated compilation flow is described based on the Trimaran VLIW compiler which achieves explicitly parallel instructions from C code. Benchmarks from the Media-Bench suite are being used to test the performance of the parallelism of both the software and hardware components.","PeriodicalId":38467,"journal":{"name":"Giornale di Storia Costituzionale","volume":"56 1","pages":"499-502"},"PeriodicalIF":0.0,"publicationDate":"2004-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89478126","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}

High programmability resolution is obtained by using a non-uniform sampling scheme without modifying any capacitor value. As a result, capacitor spread and total capacitor area are reduced as compared to traditional solutions and, hence, test area overhead can be minimized. To prove the feasibility of the proposed approach, the design and the implementation of a 0.35 /spl mu/m CMOS SC spectrum analyzer are discussed. Simulation results confirm that high measurement accuracy can be achieved.","PeriodicalId":38467,"journal":{"name":"Giornale di Storia Costituzionale","volume":"8 1","pages":"595-598"},"PeriodicalIF":0.0,"publicationDate":"2004-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87002804","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}

We investigate their suitability for low energy applications, where long battery life and delay tolerance is the principal design goal, and where performance is not a critical requirement. Three adder circuits are studied -two dynamic and one based on pass-transistor logic. All adders combine dual-rail and bundled-data circuits. The circuits are simulated at a wide supply-voltage range, down to their minimal operating point. Leakage energy (at 0.18 /spl mu/m) is found to be negligible. Transistor count is found to be an unreliable predictor of energy dissipation. Keepers in dynamic logic are eliminated when possible. The least amount of energy is dissipated by a modified version of a two-bit dynamic adder originally proposed by K.S. Chong et al. (see Int. Symp. Circuits and Systems, 2002).","PeriodicalId":38467,"journal":{"name":"Giornale di Storia Costituzionale","volume":"34 1","pages":"164-167"},"PeriodicalIF":0.0,"publicationDate":"2004-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88042806","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}

Power dissipation of the presented DFF is significantly reduced by leakage control using the stack effect. A variety of DFF and a shift-register, using the stacking effect approach, have been implemented in 0.18 /spl mu/m standard CMOS technology to compare the proposed DFF and shift-register structures with existing alternatives, showing an up to 63 % reduction in power dissipation of a shift-register at 30 Hz frequency.

One of the principal challenges in realizing modern wireless communication links in the EHF band are phenomena occurring during electromagnetic wave propagation through the atmosphere and in the linear systems of the receiver. A space-frequency approach for analyzing wireless communication channels operating in the EHF band is presented. The signal analysis is studied in the frequency domain, enabling consideration of ultra wide band modulated signals. The theory is employed for the analysis of a communication channel operating at EHF that utilizes pulse amplitude modulated signals.","PeriodicalId":38467,"journal":{"name":"Giornale di Storia Costituzionale","volume":"120 1","pages":"57-60"},"PeriodicalIF":0.0,"publicationDate":"2004-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86171501","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 LURU algorithm maps a combinational circuit to a network of K-input lookup tables (LUTs). The LURU algorithm uses content addressable memory (CAM) to enable parallel pattern matching in a Boolean network. As a result, it is possible to perform global searches quickly within an entire Boolean network, thus increasing the quality of results compared to algorithms of local scope. To utilize CAM for the LURU algorithm, a circuit is described as a set of one dimensional text strings, each of which independently represents the topology of a portion of the circuit. The LURU algorithm was tested with specially partitioned circuits from the ISCAS'85 set of combinational benchmarks. These results are compared with results obtained from the mapping algorithms FlowMap and CutMap. It is demonstrated that using LURU leads to an average of 25% area improvement over both FlowMap and CutMap.","PeriodicalId":38467,"journal":{"name":"Giornale di Storia Costituzionale","volume":"1 1","pages":"599-602"},"PeriodicalIF":0.0,"publicationDate":"2004-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82976670","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}
