Power/Performance Analysis for System-Level Design
In this talk, I will provide an overview of my recent work on formal
and semiformal approaches for power/performance analysis of portable
multimedia systems. More precisely, I will focus on the problem of
system-level design for average-case performance, which is timely,
extremely important, yet not very-well developed today.
The proposed methodology complements the existing techniques for
extreme-case performance analysis by incorporating the environment
characteristics into system performance evaluation. Being targeted
at system-level, the results of this analysis are not confined to
any particular hardware/software implementation so they offer the
generality and flexibility designers need in planning the embedded
The formalism and techniques that I will present in detail are powerful,
concise, and provide elegant solution to system modeling. They have been
used successfully in other domains to model complex interacting systems.
Their adaptation for platform-based design of multimedia embedded systems
is a very interesting and challenging task with very promising results.
