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 the KSAR Lite stack to improve memory optimization for the lighter ECUs
KSAR Lite Highlights
- Platform software for Smaller ECUs
- Architecture based on AUTOSAR Implementation Conformance Class- ICC2
- Single Configuration Tool for Classic, Adaptive and LW-KSAR
- Bus Level Compatibility with Classic AUTOSAR ECUs
