AURIX Performance Benchmarking with Dhrystone and CoreMark

This white paper examines the performance benchmarking of Infineon’s TriCore™ architecture using Dhrystone and CoreMark benchmarks. It outlines the methodology for executing these benchmarks on the AURIX™ TC3x and TC4x device families, detailing the tools and compilers utilized for testing. The paper discusses the significance of benchmarking in the semiconductor industry, particularly for microcontrollers, and provides a historical context for the Dhrystone and CoreMark benchmarks. It highlights the limitations and pitfalls associated with these benchmarks, including their dependence on compiler optimizations and their inability to fully capture real-world performance scenarios. The results of the benchmarking tests are presented, showing variations based on different compilation methods. The paper concludes with recommendations for using these benchmarks as initial indicators of performance while emphasizing the need for application-based profiling to achieve a comprehensive understanding of microcontroller performance in practical applications.
