The special requirements here are high bandwidth (2.16 Tbit/s), low latency, and flexibility in the processing algorithm. The input data come optically via 1 080 links operating at 2.5 Gbit/s. The whole system is partitioned hierarchically in 18 groups of 5+1 modules and one top module. All modules contain the same PCB, FPGA, DDR SRAM and SDRAM, but are equipped with different optional components and additional interface boards, which simplifies the hardware development significantly and reduces the production costs. Embedded PowerPC processors running Linux systems are used to implement a control and monitoring system. The system was installed in the real environment in December 2007 and is in continuous operation for cosmic data taking.","PeriodicalId":137963,"journal":{"name":"2008 International Conference on Field Programmable Logic and Applications","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125395683","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 link removal strategy that customizes the router in NoC is proposed for reconfigurable systems in order to minimize required hardware amount. Based on the pre-analyzed traffic information, links on which the communication amount is small are removed to reduce the hardware cost with enough performance being kept. Two policies are proposed to avoid deadlocks and better performance can be achieved compared with up*/down* routing on the irregular topology with links removed. In the image recognition application susan, the proposed method can save 30% of the hardware amount without performance degradation.","PeriodicalId":137963,"journal":{"name":"2008 International Conference on Field Programmable Logic and Applications","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122870306","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}

Bitstream creation is performed at run-time by merging partial bitstreams from individual component modules. The process includes the capability to create connections between the modules by selection from a set of routes found during an off-line pre-processing step. Placement and interconnection of modules must follow a precise set of rules. While restricting the number of possible module arrangements, this approach allows bitstream creation to be performed with relatively few computational resources. Using a demonstration system with a Virtex-II Pro FPGA with a PowerPC 405 CPU, the process of creating at run-time a partial bitstream for 22% of the device area takes 24 ms.","PeriodicalId":137963,"journal":{"name":"2008 International Conference on Field Programmable Logic and Applications","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123529963","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 architectures require distributed and scalable control techniques for run-time optimization of applicative parameters. Our approach is to use the game theory as an optimization model to solve the trade-off issues at run-time. We applied it to the distributed dynamic voltage frequency scaling (DVFS) management, adjusting at run-time the frequency set of each PE based on the synchronization between tasks of the application graph and the PE temperature profile. Results show that the analyzed algorithm converges to a solution in about 94% of the cases and in less than 40 calculation cycles for a 100-processor MP-SoC. It reaches an average optimization of 89% compared to an off-line centralized reference but about 140 times faster when simulating.","PeriodicalId":137963,"journal":{"name":"2008 International Conference on Field Programmable Logic and Applications","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121293223","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}

With information obtained from Xilinxpsilas XDL tool, a compact routing database for the Virtex-II/IIP/4 devices is built which only requires 96 KB of storage. A channel routing algorithm is used because of its deterministic execution time and because all routing resources in the channel are available. Sample channels are routed with the router and compared with the Xilinx PAR tool.

In order to achieve the characteristics of compactness and high-throughput, the DS-HIE architecture executes operations following a bit-serial computation scheme and adopts a Benes network as its routing resource. Implementing bit-serial computation brings the advantage of small chip area and high throughput to the DS-HIE architecture, and the Benes network ensures the high availability of the routing paths within a compact chip area. In this paper, we explain several methods, namely two data transfer methods and three feedback path methods, and provide an evaluation of the architecture. The evaluation results showed that the structure which allows for the smallest chip area comprises the dedicated wiring method for data transfer and the area effort method for routing. Further, the transistor count of the DS-HIE processor is notably smaller than that of the core 2 duo processor.","PeriodicalId":137963,"journal":{"name":"2008 International Conference on Field Programmable Logic and Applications","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126287700","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}
