With the advent of reconfigurable architectures it is now possible to support algorithms to find optimal solutions for an improved energy and throughput balance. As a result of ongoing research several online and offline techniques and algorithm have been proposed for hardware adaptation. This paper presents a novel coarse-grained reconfigurable symmetric chip multiprocessor (SCMP) architecture managed by a fuzzy logic engine that balances performance and energy consumption. The architecture incorporates reconfigurable level 1 (L1) caches, power gated cores and adaptive on-chip network routers to allow minimizing leakage energy effects for inactive components. A coarse grained architecture was selected as to be a focus for this study as it typically allows for fast reconfiguration as compared to the finegrained architectures, thus making it more feasible to be used for runtime adaption schemes. The presented architecture is analyzed using a set of OpenMP based parallel benchmarks and the results show significant improvements in performance while maintaining minimum energy consumption.","PeriodicalId":101655,"journal":{"name":"2010 NASA/ESA Conference on Adaptive Hardware and Systems","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2010-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134122118","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}

Data compression helps to mitigate this problem and, therefore, it is currently seen as a mandatory stage for most of the missions, although the available on-board processing power is often modest. In many cases, data compression must be performed without losses. FAPEC is a lossless data compression algorithm that typically offers better ratios than the CCSDS 121.0 recommendation on realistic data sets. Its compression efficiency is higher than 90% of the Shannon limit in most cases, even in presence of large amounts of noise and outliers. FAPEC has been successfully implemented in software and its low-complexity algorithm also seemed suitable for a hardware implementation. In this paper we describe a prototype FPGA implementation which has been developed targeting the antifuse radiation-hardened RTAX Actel family. We have assessed that FAPEC can be easily implemented in hardware without requiring an external memory. The prototype presents an initial throughput of 32 Mbit/s and a complexity of 120 Kgate, hence being a compact and a robust solution for generic lossless compression. Finally, we discuss potential improvements that could easily boost the performance beyond the barrier of 100 Mbit/s.","PeriodicalId":101655,"journal":{"name":"2010 NASA/ESA Conference on Adaptive Hardware and Systems","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2010-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129385276","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}
