Coremark benchmark from Github
To build the elf and binary file
make all
To compute the score:
coremark score = nb iteration / time (in seconds)
coremark per MHz = score / frequency (in MHz)
Core works @ 500 MHz
With compilation -o0 : 45 ms for 10 iteration = 0.44 coremark / MHzs With compilation -o1 : 7 ms for 10 iterations = 2.85 coremark / MHz With compilation -o2 : 10.8 ms for 10 iteration = 1.8 coremark / MHzs With compilation -o3 : 10.8 ms for 10 iteration = 1.8 coremark / MHzs
