ArduinoCoreMark

ArduinoCoreMark is a CPU performance benchmark for Arduino platform based on EEMBC CoreMark. It measures the performance of CPU by performing various tasks such as linked list processing, matrix manipulation, state machines execution.

Read the following blog post for additional information.

Requirements

CoreMark requires about 2.5 KiB (2560 bytes) SRAM. So, boards such as Arduino UNO is not supported.

Installation

ArduinoCoreMark is published on PlatformIO Registry and can be installed using the following command:

pio pkg install --library "lindevs/arduino-coremark"

Code example

#include <Arduino.h>
#include <core_arduino.h>

void setup()
{
    Serial.begin(115200);
}

void loop()
{
    startCoremark();
    delay(5000);
}
