First, we study the impact of placement on the delay unbalance in a Tree-based FPGA. Then, we propose an adaptation to the Pathfinder routing algorithm to improve the delay balance. The experimental results demonstrate that our placement and routing techniques reduce the delay unbalance significantly. They achieve 93 % of average timing balancing improvement in WDDL designs.","PeriodicalId":325631,"journal":{"name":"2009 International Conference on Reconfigurable Computing and FPGAs","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127482757","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}

In this paper we present a simple yet effective technique for increasing the scalability of a fixed-precision Montgomery multiplier. Our idea is to extend the datapath of a Montgomery multiplier in such a way that it can also perform an ordinary multiplication of two n-bit operands (without modular reduction), yielding a 2n-bit result. This conventional (n*n-≫2n)-bit multiplication is then used as a \"sub-routine\" to realize arbitrary-precision Montgomery multiplication according to standard software algorithms such as Coarsely Integrated Operand Scanning (CIOS). We show that performing a 2n-bit modular multiplication on an n-bit multiplier can be done in 5n clock cycles, whereby we assume that the n-bit modular multiplication takes $n$ cycles. Extending a Montgomery multiplier for this extra functionality requires just some minor modifications of the datapath and entails a slight increase in silicon area.","PeriodicalId":325631,"journal":{"name":"2009 International Conference on Reconfigurable Computing and FPGAs","volume":"1238 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126344302","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}

On the other hand, the development of VLSI technology allows for the creation of programmable devices with greater facilities, which not only offer a large gate density to program hardware modules, but also contain one or more embedded processors, allowing the creation of complete systems inside a single chip (SoC). The use of hardware and software components in a single electronic system allows to combine the flexibility offered by software and the high computing power and parallelism of hardware. This paper describes a Hardware-Software Co-Design (HSC) of FIC which improves the compression time, obtaining an acceleration factor between 6.6 and 8.5.

Our paper introduces an efficient dynamically reconfigurable FIR system that can adapt the number of filter coefficients, and their values, in real time. Here, dynamic reconfiguration is used to switch between different, pre-computed, fixed-point realizations of different digital filters. Our platform relies on the use of Distributed Arithmetic blocks, mapped to the specific LUTs of the underlying FPGA. Dynamic reconfiguration of the coefficients is limited to changing a small number of relevant LUT contents, while leaving the rest of the architecture intact. We investigate the dynamic system throughput as a function of the dynamic reconfiguration rate.","PeriodicalId":325631,"journal":{"name":"2009 International Conference on Reconfigurable Computing and FPGAs","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114272256","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}

This architecture can correct Single Event Upset (SEU) by utilizing both Triple Modular Redundancy (TMR) and mapping technique. Since the proposed architecture can implement all the k-input Boolean functions, it can be used instead of Look-Up Table (LUT) in current-day SRAM-based FPGAs; moreover, the proposed architecture uses the same routing architecture which is presented in current-day FPGAs, so all CAD algorithms can be used in the employed design. Experimental results show that the proposed architecture can correct 100% SEU in the configuration memory of CLB without any user intervention or reconfiguration; moreover, the required area and the power consumption are respectively 136% and 195% more than the area and the power consumption that are required by the standard 16 ×1 LUT.","PeriodicalId":325631,"journal":{"name":"2009 International Conference on Reconfigurable Computing and FPGAs","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128962810","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}
