Benchmarking an interdisciplinary concurrent design methodology for electronic/mechanical systems

Abstract

Abstract*The paper describes the evolution of an Interdisciplinary Concurrent Design Methodology (ICDM) and the metrics used to compare four generations of wearable computer artifacts produced by the methodology at each stage of ICDM's growth. The product cycle is defined, its phases, and the design information representation for each phase. Six generic axes of design activity are defined, and the concept of benchmarking a complete design methodology using these axes is introduced. In addition an approach for measuring design complexity is proposed. When applied to the four generations ot the CMU wearable computers, the ICDM has demonstrated two orders ot magnitude increase in design and efficiency.

Optimization methodology of dynamic data structures based on genetic algorithms for multimedia embedded systems

“…In addition, according to the characteristics of certain parts of multimedia applications, several transformations for DDTs and design methodologies (Smailagic et al, 1995;Benini and De Micheli, 2000;Catthoor et al, 2002) have been proposed for static data profiling and optimization considering static memory access patterns to physical memories. In this context, the use of GA-based optimization has been applied to solve linear and non-linear problems by exploring all regions of the state space in parallel (Coello et al, 2002).…”

In this context, the use of GA-based optimization has been applied to solve linear and non-linear problems by exploring all regions of the state space in parallel.…”

Application design for wearable and context-aware computers

“…The goal is to develop a new class of computing systems with a small footprint that can be carried or worn by a person and be able to interact with computer-augmented environments [1]. Since users are an integral part of the system, techniques such as user centered design, rapid prototyping, and in-field evaluation are used to identify and refine user interface models that are useful across a wide spectrum of applications [2,3]. Over two dozen wearable computers have been designed and built over the last decade, with most tested in the field.…”

“…The goals for this paper are: (1) present a map of wearable system functionality to application types and to (2) summarize examples of four user interface models.…”
