This project was done abandoned 2 months ago, and I can't remember everything very well, so the steps here may be wrong.
First, you need to clone QEMU, put judger.c into tests/plugin, and compile QEMU. You need to update the paths in Makefile.
Then you can run make all, then there will be run results in results/ directory.
Finally, you may run python test.py to find some coefficients.
It runs the code in RISC-V, and counts the number of:
- instructions
- integer division instructions
- floating point instructions
- memory access instructions
It also emulates a 4-way associative L1 cache, and counts the number of cached memory access instructions.
The python code tries to find some coefficients to calculate running time using these numbers.
