Application note

Shrinking the AUTOSAR OS: code size and

performance optimizations

1

Introduction

This application note describes the operations needed to perform code size and

performance optimization of EB's AUTOSAR OS.

EB's AUTOSAR OS is highly configurable. All the standard functionalities of the AUTOSAR

OS are available using the standard library right up to Scalability Class 4. The disadvantage

of this approach is that the kernel is often much bigger and slower than it needs, instead of

using all the techniques to avoid linking unnecessary functions and data into the final binary.

AUTOSAR OS supports the following products:

●

SPC564Axx

●

SPC560Bxx

●

SPC56ELxx

●

SPC563Mxx

●

SPC560Pxx
