Improving Memory Utilisation for Lighter ECUs

Overview

AUTOSAR stacks such as KSAR help OEMs and Tier1s to achieve software standardization. However, most of them are developed to support complex and high compute applications requiring high memory consumption while the lighter applications need only specific modules within the AUTOSAR stack. Considering this KPIT has introduced solutions to improve memory optimization for the lighter ECUs
