These networks require an extremely low-power datapath to ensure sustained scalability, and higher performance/watt. Crossbars and links form the core of a network datapath, and integrating low-swing links within these will reduce power significantly. Low-swing links however require significant custom circuit design effort to deliver good power efficiency and high bit rate, in the face of noise. As a result, low-swing links have not been able to make it to mainstream chips which rely on crossbar and link generators from RTL. In this paper, we present a datapath generator that creates automated layouts for crossbars with noise-robust low-swing links within them. To the best of our knowledge, this is the first crossbar generator that (1) creates layouts, instead of generating just synthesizable RTL; and (2) integrates noise-robust low-swing links in an automated manner. We demonstrate our generated datapath in a fully-synthesized NoC router, and observe 50% power reduction on datapath.","PeriodicalId":6357,"journal":{"name":"2011 IEEE/ACM International Conference on Computer-Aided Design (ICCAD)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86135498","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}

To reduce the pin count, broadcast addressing, by minimally grouping electrode sets with non-conflict signal merging, has emerged as a promising solution. Nevertheless, naive signal merging has the potential to cause excessive electrode actuations, which has been reported to have direct and adverse effect on chip reliability. According to recent studies, reliability is an important attribute for PDMFBs particularly developed for medical applications as it directly affects the final medical decision making. However, no research findings have been reported on the reliability problem in pin-constrained designs. To make PDMFBs more feasible for practical applications, we propose in this paper the first matching-based reliability-oriented broadcast-addressing algorithm for PDMFBs. We identify the factors that affect reliability and incorporate into the design-technique attributes that enhance reliability. Experimental results demonstrate the effectiveness of the proposed algorithm.","PeriodicalId":6357,"journal":{"name":"2011 IEEE/ACM International Conference on Computer-Aided Design (ICCAD)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85620104","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 memory organization (size, banks, sectors, etc.) is driven by an extensive analysis of memory-usage behavior for various 3D-video sequences. Considering a multiple-sleep state model, an application-aware power management scheme is employed to reduce the leakage energy of the on-chip memory. The knowledge of motion and disparity estimation algorithm in conjunction with video properties are considered to predict the memory requirements of each Macroblock. A cost function is evaluated to determine an appropriate sleep mode for the idle memory sectors, while considering the wakeup overhead (latency and energy). The complete motion and disparity estimation architecture is implemented in a 65nm low power IBM technology. The experiments (for various test video sequences) demonstrate that our architecture provides up to 80% leakage energy reduction compared to state-of-the-art. Our scheme processes motion and disparity estimation of four HD1080p views encoding at 30fps with a power consumption of 57mW.","PeriodicalId":6357,"journal":{"name":"2011 IEEE/ACM International Conference on Computer-Aided Design (ICCAD)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86302927","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}

CACTI-P supports modeling of major leakage power reduction approaches including power-gating, long channel devices, and Hi-k metal gate devices. Because it accounts for implementation overheads, CACTI-P enables in-depth study of architecture-level tradeoffs for advanced leakage power management schemes. We illustrate the potential applicability of CACTI-P in the design and analysis of leakage power reduction techniques of future manycore processors by applying nanosecond scale power-gating to different levels of cache for a 64 core multithreaded architecture at the 22nm technology. Combining results from CACTI-P and a performance simulator, we find that although nanosecond scale power-gating is a powerful way to minimize leakage power for all levels of caches, its severe impacts on processor performance and energy when being used for L1 data caches make nanosecond scale power-gating a better fit for caches closer to main memory.","PeriodicalId":6357,"journal":{"name":"2011 IEEE/ACM International Conference on Computer-Aided Design (ICCAD)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77242837","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}
