# Introduction
 
CoreMark's primary goals are simplicity and providing a method for testing only a processor's core features. For more information about EEMBC's comprehensive embedded benchmark suites, please see www.eembc.org.
 
For a more compute-intensive version of CoreMark that uses larger datasets and execution loops taken from common applications, please check out EEMBC's [CoreMark-PRO](https://www.github.com/eembc/coremark-pro) benchmark, also on GitHub.
 
This project folder is a port of CoreMark (from the official [GitHub repository](https://github.com/eembc/coremark)) for the NEORV32 processor.
 
# Building
 
To build the executable (`neorv32_exe.bin`) of the benchmark, type:
 
`> make USER_FLAGS+=-DRUN_COREMARK clean_all exe`
 
Make sure to define `RUN_COREMARK` *when invoking* `make` (via `USER_FLAGS+=-DRUN_COREMARK`).
 
To build the executable for a certain CPU configuration and a certain optimization level of the benchmark, type (`rv32imc` and `O3` in this example):
 
`> make USER_FLAGS+=-DRUN_COREMARK MARCH=rv32imc EFFORT=-O3 clean_all exe`
 
 
# Running
 
Upload the generated executable `neorv32_exe.bin` via the bootloader ('u' command) and execute it ('e' command):
 
```
