By dynamically reconnecting the datapath between calculation units, we can optimize the performance of many designs. Inspired by some prior works, we proposed a new MIMD Streaming (MIMDS) execution scheme on the aid of reconfigurable design, featuring high efficient stream processing. In this work, we also take the locality of programs into account when designing our reconfigurable architecture. Therefore, we use the permutation network [1] as our reconfigurable path, which provides less but enough reconfigurability, leading to less area cost and less power consumption. In this paper, we will take a commercial processor, C54x from Texas Instrument [2], as example, as well as detail the modification from the baseline C54x to our proposed MIMDS architecture. We show that with the extra ALUs and efficient datapath, C54x with MIMDS feature has overall 63% less execution cycles and 45% less memory access at most. Compared with traditional C54x, our design has only 12% area overhead. Besides, if we consider only configurable network, our permutation network saves 85% area compared to fully reconfigurable datapath while supports sufficient reconfigurability.","PeriodicalId":167156,"journal":{"name":"2014 IEEE Workshop on Signal Processing Systems (SiPS)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128484684","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}

Less complex techniques, such as Doppler-based imaging (which cannot provide lateral flow measurements) and basic speckle tracking algorithms (which have poor lateral accuracy), are incapable of producing high quality 3D measurements. In this paper, we first extend a technique designed to improve lateral flow accuracy for 2D velocity vector estimation, the synthetic lateral phase method, to 3D (SLP-3D). We then show that a straightforward implementation of this algorithm is too computationally complex for modern systems. Instead, we propose a two-tiered method that uses low complexity sum-of-absolute differences (SAD) for coarse-grained search and an optimized version of SLP-3D to fine tune the search for sub-pixel accuracy. We show that the proposed method (SAD+SLP-3Dopt) achieves a 9× reduction in computational complexity compared to the naive SLP-3D. Field II simulations for plug and parabolic flow using our method show a fairly high degree of accuracy in both the axial and the lateral components. Finally, we show our technique can support accurate flow imaging with up to 130 velocity estimations/sec within the power constraints of a handheld device.","PeriodicalId":167156,"journal":{"name":"2014 IEEE Workshop on Signal Processing Systems (SiPS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132739178","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}
