-Benchmarking
-============
-
-The Dhrystone and CoreMark benchmarks are still only supported by the Legacy
-Freedom E SDK. When we port the benchmarks to Freedom Metal, we will update
-this section to describe the updated build steps.
-
-Dhrystone
----------
-
-After setting up the software and debug toolchains, you can build and
-execute everyone's favorite benchmark as follows:
-
-- Compile the benchmark with the command ``make software TARGET=freedom-e300-hifive1 PROGRAM=dhrystone LINK_TARGET=dhrystone``. Note that a slightly different linker file is used for Dhrystone which stores read only data in DTIM instead of external flash.
-- Run on the HiFive1 board with the command ``make upload TARGET=freedom-e300-hifive1 PROGRAM=dhrystone``.
- This will take a few minutes. Sample output is provided below.
-- Compute DMIPS by dividing the Dhrystones per Second result by 1757, which
- was the VAX 11/780's performance. In the example below, 729927 / 1757 =
- 415 DMIPS.
-- Compute DMIPS/MHz by dividing by the clock rate: in the example below,
- 415 / 268 = 1.55 DMIPS/MHz.
-
-.. code-block:: none
-
- core freq at 268694323 Hz
-
- Dhrystone Benchmark, Version 2.1 (Language: C)
-
- <snip>
-
- Microseconds for one run through Dhrystone: 1.3
- Dhrystones per Second: 729927.0
-
-CoreMark
---------
-
-We cannot distribute the CoreMark benchmark, but following are instructions
-to download and run the benchmark on the HiFive1 board:
-
-- Download CoreMark from EEMBC's web site and extract the archive from
- `<http://www.eembc.org/coremark/download.php>`_.
-- Copy the following files from the extracted archive into the
- ``software/coremark`` directory in this repository:
-
- - ``core_list_join.c``
- - ``core_main.c``
- - ``coremark.h``
- - ``core_matrix.c``
- - ``core_state.c``
- - ``core_util.c``
-
-- Compile the benchmark with the command ``make software PROGRAM=coremark``.
-- Run on the HiFive1 board with the command ``make upload PROGRAM=coremark``.
-- Divide the reported Iterations/Sec by the reported core frequency in MHz to
- obtain a CoreMarks/MHz value.
