Regehr, John | Two case studies in predictable application scheduling using Rialto/NT | This paper analyzes the results of two case studies in applying the Rialto/NT scheduler to real Windows 2000 applications. The first study is of a soft modem-a modem whose signal processing work is performed on the host CPU, rather than on a dedicated signal processing chip. The second is of an audi... | | 2001-01-01 |

Gopalakrishnan, Ganesh | Explicit-enumeration based verification made memory-efficient | We investigate techniques for reducing the memory requirements of a model checking tool employing explicit enumeration. Two techniques are studied in depth: (1) exploiting symmetries in the model, and (2) exploiting sequential regions in the model. The first technique resulted in a significant reduc... | Verification; Model checking tool; Memory-efficient | 1995 |

Lepreau, Jay | DRAFT: work in progress - - - comments solicited evolving Mach 3.0 to use migrating threads | Like most operating systems, Mach 3.0 views threads as statically associated with a single task. An alternative model is that of migrating threads, in which a single thread abstraction moves between tasks with the logical flow of control, and "server" code is passively executed. We have compatibly r... | DRAFT | 1993 |

Mathew, Binu K.; Davis, Al; Fang, Zhen | A Gaussian probability accelerator for SPHINX 3 | Accurate real-time speech recognition is not currently possible in the mobile embedded space where the need for natural voice interfaces is clearly important.

Lindstrom, Gary E. | Layered, server-based support for Object-Oriented application development | This paper advocates the idea that the physical modularity (file structure) of application components supported by conventional OS environments can be elevated to the level of logical modularity, which in turn can directly support application development in an object-oriented manner. We demonstrate ... | Object-Oriented application development | 1995 |

Balasubramonian, Rajeev | Dynamic memory hierarchy performance optimization | Although microprocessor performance continues to increase at a rapid pace, the growing processor-memory speed gap threatens to limit future performance gains. In this paper, we propose a novel configurable cache and TLB as an alternative to conventional two-level hierarchies. This organization le... | Microprocessor performance; Processor-memory speed gap | 2000 |

Orr, Douglas B. | OMOS - An object server for program execution | The benefits of object-oriented programming are well known, but popular operating systems provide very few object-oriented features to users, and few are implemented using object-oriented techniques themselves. In this paper we discuss a mechanism for applying object-oriented programming concepts to... | OMOS; Object server | 1992 |

Gopalakrishnan, Ganesh | Performance analysis and optimization of asynchronous circuits | Asynchronous/Self-timed circuits are beginning to attract renewed attention as promising means of dealing with the complexity of modern VLSI designs. However, there are very few analysis techniques or tools available for estimating the performance of asynchronous circuits.

Brunvand, Erik L. | A comparison of modular self-timed design styles | State-machine sequencing methods in modular 2-phase and 4-phase asynchronous handshake control are compared. Design styles are discussed, and the sequencers are tested against each other using a medium-scale minicomputer test design implemented in FPGAs. Seven 4-phase sequencers are tested. In these... | Self-timed; State-machine sequencing; Asynchronous handshake control | 1995 |

Zhang, Lixin | A comparison of online superpage promotion mechanisms | The amount of data that a typical translation lookaside buffer (TLB) can map has not kept pace with the growth in cache sizes and application footprints. As a result, the cost of handling TLB misses limits the performance of an increasing number of applications. The use of superpages, multiple adjac... | Superpages; Translation lookaside buffer; TLB | 1999 |
