Memcopy benchmarking demo

Introduction

This application, internally called as AUTOSAR benchmarking application is used for benchmarking several KPIs such as:

  • I-cache miss

  • D-cache miss

  • memory copy performance on different cores

  • with options such as XIP, non-XIP

  • ability to run software on other cores

  • run with CCS or SBL etc.
