MiBench ported for IoT devices.
All benchmarks include barebench.h. This file contains the main() used in building every benchmark and determines the number of benchmark trials and what happens when a benchmark attempts to print to the screen.
You will need a cross-compiler for your target platform. The default target is the ARM-Cortex-M0+. The easiest way to get a working cross-compiler for the Cortex-M0+ is to download the prebuilt binaries from Launchpad.net.
Whatever toolchain you go with, update the paths and commands in the global make file.
cd to the appropriate benchmark directory.
make
Running make produces several useful files:
main.elf an ELF executable suitable for loading to a board or simulator using GDB
main.bin a raw binary suitable for loading directly in to the memory of a board or a simulator
main.lst assembly listing
Running make clean will remove all files produced during compilation.
To build all benchmarks and move the resulting bin files to the repo's top-level directory, run buildAll.sh.
memmap contains the memory map used by the linker to place program sections. Edit this file to change the size of memory or the location/size of individual program sections (e.g., stack and heap).
vectors.s contains the exception jump table and the execution entry point _start and exit point exit. You may need to edit this file if you target a different instruction set than the ARMv6-M.
putget.s contains low level functions written in assembly. Edit the putchar function in this file to change the behavior of all C-level printing operations.
supportFuncs.c contains functions needed to port newlib to our target platform.
