ABSTRACT

This paper presents a seamless and continuous integration approach that allows to gradually introduce performance improvements while preserving an established functional baseline in an embedded system with demanding characteristics requirements. The following topics will be addressed: how performance improvements can be broken down in small steps with objective and measurable goals, how to predict, verify and measure them. An ad-hoc fault localization strategy is also proposed to exploit the multi-core DSP hardware and minimize human troubleshooting time. The purpose and benefits of this approach is to avoid a big bang and find critical faults very early in the project and secure project lead time, quality and budget.
