As network speeds are increasing, the demand for hardware acceleration of packet classification in FPGAs or ASICs is growing. Nowadays algorithms implemented in hardware can achieve multigigabit speeds, but suffer with great memory overhead. We propose a new algorithm and hardware architecture which reduces memory requirements of decomposition based methods for packet classification. The algorithm uses prefix coloring to reduce large amount of Cartesian product rules at the cost of an additional pipelined processing and a few bits added into results of the longest prefix match operation. The proposed hardware architecture is designed as a processing pipeline with the throughput of 266 million packets per second using commodity FPGA and one external memory. The greatest strength of the algorithm is the constant time complexity of the search operation, which makes the solution resistant to various classes of network security attacks.","PeriodicalId":231389,"journal":{"name":"14th IEEE International Symposium on Design and Diagnostics of Electronic Circuits and Systems","volume":"106 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133387439","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}

Various methods exist for the specification of reconfiguration schedules, which are either too simple for the description of complex processes, or are inherently difficult to verify. We employ a variant of the π-calculus for modelling dynamic partial reconfiguration. The π-calculus is a process algebra originally constructed for modelling communicating systems, but can be repurposed as a scheduling method for dynamic partial reconfiguration on FPGA devices. In order to apply this type of scheduling for the design of hardware systems, it has to be determined how to allocate the scheduled tasks on the device. By use of a verification tool for the π-calculus, constraints can be extracted from a given system specification. These constraints form the basis to derive the placement of the reconfigurable areas in an automatic fashion.","PeriodicalId":231389,"journal":{"name":"14th IEEE International Symposium on Design and Diagnostics of Electronic Circuits and Systems","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127480987","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 fault evaluation is carried out on a behavioral model to compare the coverage of the proposed test approach with the one obtained from a functional test. Then, the analysis is moved to a transistor level implementation of the ADC to establish the threshold limits for the DfT circuit that maximize the fault coverage figure of the test approach.","PeriodicalId":231389,"journal":{"name":"14th IEEE International Symposium on Design and Diagnostics of Electronic Circuits and Systems","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114854927","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}

Especially for critical systems it is becoming a crucial property with increasing system complexity and shrinking technology dimensions. Analog and mixed-signal systems are an important part of these critical systems. Until now little effort has been put into dependability of analog and mixed-signal systems, especially front/back-ends. This paper presents a new system-level platform for enhancing and analyzing the dependability of analog and mixed-signal front-ends in SoCs. Markov analysis has been used to theoretically investigate the dependability enhancement of these analog and mixed-signal front-ends based on this platform. Simulations in VHDL-AMS have also been conducted for an example target system consisting of a temperature sensor, operational amplifier and ADC to illustrate this platform. The gain parameter of the whole system, taken as an example of potential dependability hazard, has been investigated and enhanced based on this platform. The results show that this proposed platform is effective and has the potential to investigate and enhance dependability at system level.","PeriodicalId":231389,"journal":{"name":"14th IEEE International Symposium on Design and Diagnostics of Electronic Circuits and Systems","volume":"89 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132273315","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 adoption of a 3D NoC design depends on the performance and manufacturing cost of the chip. Therefore, a study of the placement of the TSV, that connects different layers of a 3D chip, is crucial. A 64-core 3D NoC is modeled based on state-of-the-art 2D chips. We discuss the number of TSVs required for a 3D NoC. Different placements of layer-layer connections are explored. We present benchmark results using a cycle accurate full system simulator based on realistic workloads. Experiments show that under different workloads, the average network latencies in two configurations (full and quarter connection) are reduced by 14.78% and 7.38% respectively, compared with the one-eighth connection design. The improvement of performance is a trade-off of manufacturing cost. Our analysis and experiment results provide a guideline for selecting optimal number of TSVs in 3D NoCs.","PeriodicalId":231389,"journal":{"name":"14th IEEE International Symposium on Design and Diagnostics of Electronic Circuits and Systems","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122038683","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}

It is shown how the methodology can be used to decrease test time of component under test if scan chain is reorganized. The principles of the methodology are based on eliminating some types of faults in the physical layout and subsequent reduction of the number of test vectors needed to test the scan chain. As a result, component test application time is decreased. The methodology was verified on several circuits, experimental results are provided and discussed. It is expected that the results of our methodology can be used in mass production of electronic components where any reduction of test time is of great importance.","PeriodicalId":231389,"journal":{"name":"14th IEEE International Symposium on Design and Diagnostics of Electronic Circuits and Systems","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125205555","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}
