Because of the increasing complexity of flash-based storage devices, however, it is more difficult to achieve good power-efficiency without considering an energy-efficient storage device design. In this paper, we investigate the potential benefit of dynamic voltage/frequency scaling (DVFS) on the energy-efficiency of flash-based storage devices. We first develop a performance/power model for a flash device by using an FPGA-based flash device platform. We then propose a simple DVFS heuristic algorithm that exploits workload fluctuations of a flash device to achieve a significant reduction in energy consumption without performance degradation. Experimental results show that a flash device with DVFS can reduce energy consumption by up to 20%-30%.","PeriodicalId":380183,"journal":{"name":"2010 International SoC Design Conference","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124118377","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 order to make the real-time 3D applications feasible, efficient multview video coding (MVC) scheme is desired. However, the system throughput requirement on a high definition (HD) MVC encoder is at least two times higher than the current highest throughput H.264/AVC encoder design. In order to meet the target HD MVC specifications, the system scheduling analysis for the HD MVC encoder is performed in this paper. By the 8-stage MB pipeline system architecture with view-parallel MB-interleaved system scheduling and other in-core computation optimizations, the proposed HD MVC encoder design provides about 339% to 1536% higher system throughput than the previous HD H.264/AVC encoder chips[4][5][6] and therefore the real-time HD MVC encoding can be achieved.","PeriodicalId":380183,"journal":{"name":"2010 International SoC Design Conference","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132710631","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}

Developing processors network systems tailored to a particular application domain is critical and design-time consuming in order to achieve highperformance customized solutions. The effectiveness of such approaches largely depends on the availability of an ad hoc design methodology. This paper illustrates a new design flow that enables to instantiate a generic Homogeneous Network of Communicating Processors (called HNCP) tailored for a targeted application. The HNCP is generated with a tool that avoids fastidious manual editing operations for the designer. Specific lightweight communication functions have been developed to fasten the programming of the MP-SoC network. A case study (image texture analyzes) is presented to illustrate the proposed MP-SoC design methodology and enables to focus on architecture exploration, instantiated scheme of parallelization and timing performance.","PeriodicalId":380183,"journal":{"name":"2010 International SoC Design Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130004084","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 can support different video standards such as MPEG-1/2/4, VC-1 and H.264 AVC. Moreover, the particular part of this architecture does not use any multiplier and ROM circuit; it only needs adders and shifters. In digital circuit, the area of adders and shifters are superior to multipliers and ROM, The reconfigurable IDCT architecture only needs 13 adders in the adder kernel. Finally, we realize this architecture by using 0.18um technology to accomplish the chip design. The experimental result shows the total gate counts only 12.4 K. Moreover, the power consumption is 4.85mW@100MHz.

An important factor that influences the choosing of a specific FEC technique in a nano-scale system implementation is its real-time performance, namely its computational complexity. In this paper, we propose a set of rules to decide whether a variable node in a LDPC decoder should update its value in subsequent iterations of the decoding process, or be considered as converged. We show that by carefully choosing the convergence rules for variable nodes, significant reduction of decoding complexity can be achieved with endurable performance loss.","PeriodicalId":380183,"journal":{"name":"2010 International SoC Design Conference","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133353717","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}

Fusion is achieved by estimating the weighting parameters which contain the properties of IR image and by combining the VR and IR images using the parameters. Specifically, the weighting parameters are calculated from the estimated illumination and detail components by a weighted low pass filter (WLPF). In addition, for a user preference, we compress dynamic range of the fused image using a retinex technique and adjust contrast/color based on global color distribution.

The conventional DTM techniques adopted in microprocessors based on DVFS are not suitable in the context of SoCs as they tend to have multiple voltage and frequency domains. In this paper we propose a reactive and a predictive DTM technique using bus arbitration. Based on the thermal profile the bus grants and hence the bus transactions are controlled. This regulates the data flow which reduces the activity in the functional units. The results show that the on-chip temperature can be maintained 3–5°C below the chip temperature threshold with a worst case performance penalty of 5% and a fast response time of at most 5 clock cycles. The hardware cost of implementing the proposed scheme is 3619.7μm2 in 45nm technology, which is less than 0.06% of the chip area. Apart from its simplicity, lower cost and effectiveness, the solution is non-intrusive on the design and scalable to many cores.","PeriodicalId":380183,"journal":{"name":"2010 International SoC Design Conference","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117320079","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}
