We recommend precise definitions for the concept of “predictability”, and present predictability issues at completely different abstraction ranges in embedded system design. First, we contemplate timing predictability of processor instruction sets. We current methods for attaining timing predictability on multicores. Finally, we talk about tips on how to deal with predictability on the stage of networked embedded techniques where randomly occurring errors must be considered. We additionally inventory pre-cuts, patterns, notions and kits, so you’ll find a way to spend more time quilting and fewer time prepping.

This dependence on the architectural development is of rising concern to the developers of timing evaluation tools and their customers, the developers in business. The problem reaches a model new degree of severity with the advent of multi-core architectures in the embedded domain. This article describes the architectural influence on static timing analysis and provides recommendations as to worthwhile and unacceptable architectural options.…
