Brunvand, Erik L. | Reduced latency self-timed FIFO circuits | Self-timed flow-through FIFOs are constructed easily using only a single C-element as control for each stage of the FIFO. Throughput can be very high in FIFOs of this type because new data can be sent to the FIFO after communicating locally with only the first element of the FIFO. Therefore the thro... | FIFO circuits; Self-timed; Flow-through; Reduced latency | 1994 |

Carter, John B. | Reducing consistency traffic and cache misses in the avalanche multiprocessor | For a parallel architecture to scale effectively, communication latency between processors must be avoided. We have found that the source of a large number of avoidable cache misses is the use of hardwired write-invalidate coherency protocols, which often exhibit high cache miss rates due to exces... | Consistency traffic; Cache misses; Parallel architecture; Communication latency | 1995 |

Balasubramonian, Rajeev | Reducing the complexity of the register file in dynamic superscalar processors | Dynamic superscalar processors execute multiple instructions out-of-order by looking for independent operations within a large window. The number of physical registers within the processor has a direct impact on the size of this window as most in-flight instructions require a new physical register a... | Dynamic superscalar processors; Register file; Instruction-level parallelism; Microarchitecture; Reorder buffer | 2001 |

Gopalakrishnan, Ganesh | Refactoring SPIN for safety | We show how to refactor SPIN for safety model checking resulting in a compact model checker occupying less than 200 lines of code without appreciable loss of performance while reusing much of SPIN?s front-end facilities. In addition to being far easier to understand and being eminently suitable a... | Model checking; SPIN | 2006-02-14 |

Zhang, Lixin | Reference manual of impulse system calls | This document describes the Im pulse system calls. The Impulse system calls allow user applications to use remapping functionality provided by the Impulse Adaptive Memory System to remap their data structures. Impulse supports several remapping algorithms.

Lindstrom, Gary E. | Referencing and retention in block-structured coroutines | The combination of coroutines with recursive procedures is characteristic of many modern higher-level languages offering advanced control structures (e.g. SIMULA-67, SL5, Interlisp, etc.). We say a language has block-structured coroutines (BSCRs) when static nesting considerations govern the usage o... | Block-structured; BSCR | 1979 |

Mueller, Timothy I. | Refinement estimation of B-spline curves and surfaces | An algorithm for refinement estimation for B-spline curves is presented. The algorithm uses approximations to the curvature and arc length to decide how a curve should be refined. The algorithm can also be used to produce isoparametric curves or polygonal tessellations from a Bspline surface. | B-spline; Curves; Surfaces; Algorithm; Curvature; Arc length; Isoparametric curves; Polygonal tessellations | 1988 |

Zachary, Joseph L. | Reflections on metaprogramming | The spread of object-oriented technology has led to object-oriented programming languages with object-oriented implementations. By encapsulating part of t h e semantics of a language within a set of default classes and empowering the programmer to derive new versions of these base classes, a designe... | Metaprogramming | 1993 |

Brunvand, Erik L.; Gopalakrishnan, Ganesh; Hurdle, John Franklin | Reliable interface design for combining asynchronous and synchronous circuits | Abstract: In order to successfully integrate asynchronous and synchronous designs, great care must be taken at the interface between the two types of systems. Synchronizing asynchronous inputs with a free running clock can cause well-known problems with metastability in the synchronization circuits... | | 1993 |

Cole, Edwin Randolph | The removal of unknown image blurs by homomorphic filtering | This report describes a homomorphic method for the estimation and removal of unknown image blurs, which are presumed to have been caused by a linear stationary system. Previous methods have required a more or less perfect a priori knowledge of the identity of the blur. the method described here requ... | Homomorphic filtering; Removal; Image blurs; Blurred image | 1974 |

Bhanu, Bir | Representation and shape matching of 3-D objects | A three-dimensional scene analysis system for the shape matching of real world 3-D objects is presented. Various issues related to representation and modeling of 3-D objects are addressed. A new method for the approximation of 3-D objects by a set of planar faces is discussed.

Chatterjee, Niladrish; Balasubramonian, Rajeev; Davis, Alan L. | Rethinking DRAM design and organization for energy-constrained multicores | DRAM vendors have traditionally optimized for low cost and high performance, often making design decisions that incur energy penalties. For example, a single conventional DRAM access activates thousands of bitlines in many chips, to return a single cache line to the CPU. The other bits may be access... | DRAM power consumption; Data-center power; Multicore memory; Trapeze Interactive Poster | 2010-03-15 |
