Virtual environment walk through applications are generally enhanced by a user’s interactions within a simulated architectural space, but the enhancement that stems from changes in spatial sound that are coupled with a user’s behavior are particularly important, especially within regard to creating a ’sense of place’. When accompanied by stereoscopic image synthesis, spatial sound can immerse t...

As system complexity grows, cycle-accurate simulation experiments become inordinately time consuming. Most approaches to accelerating architectural simulation model only portions of an application in detail. Detailed simulation begins with architectural state from earlier portions of the execution. Constructing this requires fast-forwarding: modeling effects of earlier instructions without mode...

This paper reports on an ongoing research project on an "nonpencil" approach in generating architectural forms using nontraditional geometries. Space curves are investigated to determine nodal points in 3D space, which are then interpreted into common architectural elements. The nodal points are used in a variety of ways to generate walls, columns, floors, and volumes. The determination of form...

Architectural knowledge is reflected in various artifacts of a software product. In a software product audit this architectural knowledge needs to be uncovered and its effects assessed in order to evaluate the quality of the software product. A particular problem is to find and comprehend the architectural knowledge that resides in the software product documentation. In this article, we discuss...

The shared-memory, multi-threaded PARSEC benchmark suite is intended to represent emerging software workloads for future systems. It is specifically intended for use by both industry and academia as a tool for testing new Chip Multiprocessor (CMP) designs. We analyze the suite in detail and identify bottlenecks using hardware performance counters. We take a systems-level approach, with an empha...

Interest in synthesis of Application Specific Instruction Processors or ASIPs has increased considerably and a number of methodologies have been proposed in the last decade. This paper attempts to survey the state of the art in this area and identifies some issues which need to be addressed. We have identified the five key steps in ASIP design as application analysis, architectural design space...
