The CORDIC array processor element (CAPE) is a single chip VLSI implementation of a processor element for the Brent-Luk-VanLoan systolic array which computes the SVD of a real matrix. The array utilizes CORDIC (coordinate rotation digital computer) arithmetic to perform the vector rotations and inverse tangent calculations in hardware. A six-chip prototype of the processor has been implemented as TinyChips using the MOSIS fabrication service. Experienced gain from designing the prototype helped in the design of integrated single-chip version.

These tools facilitate the generation of parametric models incorporating fixed and/or variable topologies for a wide range of analog and digital blocks. The macro/behavioral models can operate at several levels of complexity. The highest level models accurately emulate model parametric variation with power supply, transient supply currents, and supply interference effects. Two methodologies are available for defining behavioral models for logic blocks. An even-driven native logic simulator, FLOGIC, has been developed to seamlessly interact with the SPICE engine. FLOGIC provides a systematic and convenient method to create behavioral functions. These functions provide higher accuracy by including second-order effects such as dependencies of propagation delay and thresholds on input signals.<<ETX>>","PeriodicalId":163406,"journal":{"name":"Proceedings Ninth Biennial University/Government/Industry Microelectronics Symposium","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123750260","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 LZ-based compression method is a powerful technique and gives high compression efficiency for text and image data. The architecture is systolic and uses the principles of pipelining and parallelism in order to obtain high speed and throughput. Hardware schemes are proposed for decompressing data that has been compressed using the LZ method. The data compression hardware can be integrated into real-time systems so that data can be compressed and decompressed on-the-fly. A prototype CMOS VLSI chip has been designed and fabricated using CMOS 2-micron technology implementing a systolic array of nine processors. The proposed hardware can yield compression rates of about 20 million characters per second.<<ETX>>","PeriodicalId":163406,"journal":{"name":"Proceedings Ninth Biennial University/Government/Industry Microelectronics Symposium","volume":"166 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126739090","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 approach is a synergistic one that combines fracture mechanics analyses and experiments to quantify slow crack in the films. A viscoelastic fracture model is used to deduce the crack growth history from load-point displacement records measured during long-term fracture tests of the films. The rate of crack growth is found to depend very strongly upon the crack driving force as measured by the stress intensity factor. Hence, small changes in the stress intensity factor can produce dramatic changes in the crack growth rate in the materials investigated.<<ETX>>","PeriodicalId":163406,"journal":{"name":"Proceedings Ninth Biennial University/Government/Industry Microelectronics Symposium","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121492494","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}
