The Abstract Machine (AM)
How to build benchmark flash image
- clone
nexus-am
from github:
git clone git@github.com:OpenXiangShan/nexus-am.git
- enter benchmark directory (using
apps/coremark
as an example):
cd /apps/coremark
make ARCH=riscv64-xs-flash
cd ./build
ls
- you will find a ".bin" file, this is a benchmark image in flash
How to use the prepared flash image to do simulation
- assuming you have a
XiangShan
repo, the commit ID should be newer than 188f739de96af363761c0f2b80b95b70ad01e0fc - make
emu
build - use
-F
to load the image in flash:
./emu -F $AM_HOME//apps/coremark/build/coremark-riscv64-xs-flash.bin -i ../ready-to-run/coremark-2-iteration.bin 2>debug.log
NOTE: use
-i
to specify the initial ram image, or a ramdom file if you do not care.
