This locking mechanism can be used to detect malicious modifications to the hardware design, also known as a hardware Trojan, in situations where such modifications result in a change to the physical placement of the design on the IC. However, careful consideration is needed when designing ring oscillators for such a scenario to guarantee the integrity of the locking mechanism. This paper presents a case study in which flaws discovered in a ring oscillator-based Trojan detection scheme allowed for the circumvention of the security mechanism and the implementation of a large and diverse set of hardware Trojans, limited only by hardware resources.","PeriodicalId":354015,"journal":{"name":"2011 IEEE 29th International Conference on Computer Design (ICCD)","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128988609","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}

We propose a scalable and cooperative distributed thermal management technique 1 which works based on the cooperation of local controllers deployed in some of the cores. Through low overhead message passing, these controllers communicate in order to exchange temperature and performance related information which is used to find the best thermally safe set of frequency settings for the cores. Experimental results show that for our technique can successfully reduce the deadline miss rate by 47.16% in average compared to localized thermal management techniques while successfully satisfying temperature constraints.","PeriodicalId":354015,"journal":{"name":"2011 IEEE 29th International Conference on Computer Design (ICCD)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122076828","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 proposed circuit applies a shaped wordline voltage pulse during read mode and a boosted wordline pulse during write mode. During read, the applied shaped pulse is tuned at nominal voltage for short period of time, whereas for the remaining access time, the wordline voltage is reduced to a lower level. This pulse results in improved read noise margin without any degradation in access time which is explained by examining the dynamic and nonlinear behavior of the SRAM cell. Furthermore, during hold mode, the wordline voltage starts from a negative value and reaches zero voltage, resulting in a lower leakage current compared to conventional SRAM. Our simulations using TSMC 65nm process show that the proposed wordline driver results in 2X improvement in static read noise margin while the write margin is improved by 3X. In addition, the total leakage of the proposed SRAM is reduced by 10% while the total power is improved by 12% in the worst case scenario of a single SRAM cell. The total area penalty is 10% for a 128Kb standard SRAM array.","PeriodicalId":354015,"journal":{"name":"2011 IEEE 29th International Conference on Computer Design (ICCD)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117095140","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 clock signal carried by the distribution network has to reach every end node at the same time to ensure synchronized switching. Due to mismatches among different nodes of the H-tree, the clock transitions among the final nodes of the distribution tree show some time difference, the maximum of which is called clock skew. In modern CMOS technologies, copper interconnect is popular for high level interconnects such as clock and power routing. Carbon Nanotube (CNT) exhibits less resistivity than copper making it a better material for interconnect. This paper compares the impact on clock skew of H-tree clock distribution network by replacing the traditional copper interconnects with carbon nanotube interconnects. By applying temperature mismatch, threshold voltage mismatch, and process mismatch, our findings show that using carbon nanotube interconnects reduces the clock skew significantly compared to traditional copper interconnects.","PeriodicalId":354015,"journal":{"name":"2011 IEEE 29th International Conference on Computer Design (ICCD)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122802555","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 introduce and study a GALS Network-on-Chip based on the Globally-Ratiochronous, Locally-Synchronous (GRLS) paradigm. GRLS constrains all switch frequencies to be rationally-related but enables the use of efficient interfaces which reduce the latency of the network 60% compared to GALS solutions and obtains better throughput-per-power ratios compared to synchronous and mesochronous solutions.","PeriodicalId":354015,"journal":{"name":"2011 IEEE 29th International Conference on Computer Design (ICCD)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133402449","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}

Phase-Change Memory (PCM) is increasingly viewed as an attractive alternative for the memory sub-system of future microprocessor architectures, mainly because of its inherent ability to scale deeply into the nanoscale regime, and its low power consumption. However, PCM's write performance is its Achilles' heel, especially when compared to the prevalent DRAM technology. This weakness necessitates the deployment of hybridized solutions that fuse DRAM and PCM, in order to attain high overall system performance. In this paper, we set out to explore how various DRAM/PCM hybrid configurations affect system performance and energy consumption, and then proceed with the presentation of a novel architecture that maximizes performance without adversely affecting power efficiency. An energy-delay product improvement of 42.2%, on average, over conventional hybrid structures, is demonstrated.","PeriodicalId":354015,"journal":{"name":"2011 IEEE 29th International Conference on Computer Design (ICCD)","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133304579","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}

Recently, the technology of multi-level cell (MLC) for PCM has been developed and a high capacity memory system can be implemented by storing multiple bits in a cell. However, programming MLC PCM involves the program-and-verify scheme. Thus, the energy of programming intermediate states in MLC PCM is considerably larger than that of single-level cell (SLC) PCM. To mitigate the MLC energy overhead, we propose an energy-efficient PCM architecture using data encoding write based on the observation that there are significant value-dependent energy variations in programming MLC PCM. In addition, data comparison write (DCW) is adopted to enhance the effectiveness of the proposed data encoding architecture for MLC PCM. Simulation results show that this encoding architecture achieves 9.6% average energy saving (up to 19.8%) on the plain MLC PCM system, and 12.9% average energy saving (up to 26.7%) on the DCW-adopted MLC PCM system1.","PeriodicalId":354015,"journal":{"name":"2011 IEEE 29th International Conference on Computer Design (ICCD)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114814205","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}
