Introduction
This example shows an application for benchmarking the FreeRTOS SMP kernel and single core FreeRTOS kernel using dhrystone benchmarking.
The application runs the the dhrystone benchmarking demo using the given number of threads and iterations and logs the results as the number of dhrystones run per second.
The application runs with thread number equal to 1, 2, 5 and 10, with iteration number 30000000.
Supported Combinations
- Attention
- A53 NORTOS, A53 FREERTOS and A53 FREERTOS SMP support is experimental and is NOT supported by TI.
