It guarantees that the exact result of an algorithm lies within the computed tolerance bounds. In ill-conditioned cases these bounds may be extremly wide and although the statement still remains valid, it is in practice worthless. Methods which have been recently introduced as E-methods provide the possibility of successively diminishing the tolerance. Furthermore, the existence and uniqueness of the solution is proved (in a mathematical sense) by the computer. These methods combine the concepts of interval analysis with the computer arithmetic defined by Kulisch and Miranker. They are based on fixed point theorems and an exact scalar product is essential for their implementation.","PeriodicalId":424620,"journal":{"name":"1987 IEEE 8th Symposium on Computer Arithmetic (ARITH)","volume":"119 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1987-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115176355","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}

Both are able to compute the product of two n bit numbers with a delay of n cells, rather 2n−l as in classical structures. The high speed operation is obtained by using pure horizontal compressors, to accelerate the horizontal signal propagation, and by adopting a suitable array structure, to shorten the vertical signal propagation. The cost and performance advantages over similar structures based on vertical compressors are discussed.","PeriodicalId":424620,"journal":{"name":"1987 IEEE 8th Symposium on Computer Arithmetic (ARITH)","volume":"117 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1987-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121496498","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}

VLSI signal processing is one such problem domain. We propose designs of systolic and semi-systolic digit serial multipliers. These multipliers are programmable i.e. one operand is pre-stored in the multiplier and the other operand is fed in a digit serial fashion. The VLSI implementation of the systolic multiplier is also given. This systolic multiplier is used in our VLSI signal processing system.","PeriodicalId":424620,"journal":{"name":"1987 IEEE 8th Symposium on Computer Arithmetic (ARITH)","volume":"110 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1987-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132406192","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}
