Abstract

The small memory footprint and high performance characteristics required of an embedded system mandate configuration at the source level. Such configuration can be greatly accelerated with the assistance of well-designed and intuitive software tools. This class will focus on how to achieve fine-grained configuration and discuss methods for ensuring that all configurations built are coherent. We will also discuss how to manage the build process and integrate the generation and execution of tests to match a user's chosen configuration.
