The proposed hybrid architecture requires smaller number of clock cycles and circuit resources compared to other approaches. In order to reduce the number of clock cycles, we use several techniques such as data reuse, pipelining and parallel structure. We reduce the circuit resources by the use of partial tree-structure. We described the RTL circuit in Verilog HDL and synthesized the gate-level crcuit using 130 nm standard cel library. The synthesized circuit is composed of 192,772 logic gates and can process 94 D1 (720 times 480) image frame per second.","PeriodicalId":405078,"journal":{"name":"2008 International SoC Design Conference","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127053399","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}

Power grid optimization which considers the timing error risk caused by the variation becomes very important for the stable and high-speed operation of the system. Most of conventional power grid optimization algorithms use the IR drop as their objective function. However, the real goal for optimizing the IR drop is eliminating the timing error risk by it. Thus, we propose a new approach which uses the ldquotiming error risk caused by the IR droprdquo as its direct objective function. The process variation is also considered in the timing model. The new optimization method obtains variation tolerant and high quality results efficiently.","PeriodicalId":405078,"journal":{"name":"2008 International SoC Design Conference","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132908425","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}

High power consumption will lead to rapid increase in chip temperature as well. If temperature reaches beyond a certain level, chip operation becomes either slow or unreliable. Therefore various approaches for dynamic thermal management (DTM) have been proposed. In this paper, we propose a new application-oriented learning-based dynamic thermal management (LDTM) technique for a multi-core system. From repetitive executions of an application, we learn the thermal patterns of the chip, and we control the future temperature through DTM. When the predicted temperature may rise above a threshold value, we reduce the temperature by decreasing the operation frequency of the corresponding core. We implement our learning-based thermal management on an Intel's dual core system which is equipped with digital thermal sensors (DTS). The dynamic frequency scaling (DFS) is implemented to have three frequency steps on a Linux kernel. We carried out experiments using Phoronix Test Suite benchmarks for Linux. The peak temperature has been reduced by on average 7degC using our LDTM, and the overall average temperature reduced from 72degC to 65degC.","PeriodicalId":405078,"journal":{"name":"2008 International SoC Design Conference","volume":"154 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132247144","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}

Our TCT model provides a drastically simple programming model on C language which allows designers to specify system partitioning directly on the reference C code without having to deal with the time-consuming task of modeling the interactions between partitioned concurrent processes. Our TCT compiler handles automatic insertion of inter-processor communications and generates the concurrent executable model which can model a wide variety of parallel processing styles such as functional pipelining and task parallelism as well as their combinations. Our TCT trace scheduler is used to evaluate the system performance and characteristics such as execution time and communication bandwidth. Our TCT framework was also verified on a prototype MPSoC where a custom-designed processor array consisting of 6 processing elements was embedded inside the AMBA-based SoC with a very efficient processor communication interconnect which only require 2 to 6 setup cycles and 4-byte/cycle burst transfer.","PeriodicalId":405078,"journal":{"name":"2008 International SoC Design Conference","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134438333","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}
