Abstract

Functional size measurement (FSM) gives a measure of a software product and can be used to build objective estimation models for predicting project effort and duration. AUTOSAR is an architecture standard that allows collaboration on basic Electrical and Electronic (E/E) functions while providing a platform to develop new innovative ones. AUTOSAR allows portability and reuse of software functions on different hardware architectures. However, designing software functions in AUTOSAR requires several software allocation decisions which impact on E/E system performance and development costs. In this context, processor load estimation becomes an important task early in software development projects for automotive real-time embedded systems. This paper analyzes the relationship between FSM and ECU processor load in AUTOSAR, and introduces the SYMTA/S tool and an automation prototype tool developed in this study. The findings demonstrate a relationship between FSM and processor load.
