Constraint-Based Design-Space Exploration and Model Synthesis

System-Level Synthesis of Adaptive Computing Systems

With the rapid proliferation of embedded computer technology over the years, functional and performance demands from embedded computer systems have increased severely. In addition to the resource and size constraints, these systems may need to function in rapidly changing environments where performance and functional goals change over time. Adaptive Computing has been considered to meet the con...

Design Space Exploration in System Level Synthesis under Memory Constraints

This paper addresses the problem of component selection, task assignment and task scheduling for distributed embedded computer systems. Such systems have a large number of constraints of different nature, such as cost, execution time, memory capacity and limitations on resource usage. Previous approaches have concentrated on a specific class of requirements and thus they limit number of constra...

π-Resolution in Design Space Exploration

In studying the phenomenon of design we use models to envision mechanisms by which computers might support design. In one such model we understand design as guided movement through a space of possibilities. Design space explorers embody this model as mixed-initiative environments in which designers engage in exploration via human computer interaction. Constraint resolution provides a formal fra...

Optimum synthesis of a four-bar mechanism using the modified bacterial foraging algorithm

This paper presents the mechanical synthesis of a four-bar mechanism, its definition as a constrained optimization problem in presence of one dynamic constraint and its solution with a swarm intelligence algorithm based on the bacteria foraging process. The algorithm is adapted to solve the optimization problem by adding a suitable constraint-handling technique able to incorporate a selection c...
