Hi,
I run a benchmark (openjpeg) on ARM_SE, with two kinds of configurations.
The first configuration is as the following:
./build/ARM_SE/gem5.opt configs/example/se.py --cmd
./benchmark/image_to_j2k --options="-i ./benchmark/Bretagne1.bmp -o
./benchmark/Bretagne1.j2k"
The second configuration is as the following:
./build/ARM_SE/gem5.opt configs/example/se.py -d -t --caches --cmd
./benchmark/image_to_j2k --options="-i ./benchmark/Bretagne1.bmp -o
./benchmark/Bretagne1.j2k"
I have two questions about the result in stats.txt.
1. The number of instruction under the first configuration is 664046521, and
the number of instruction under the second configuration
is 653963923. I run the same benchmark, why the instruction number is
different?
2. Under both of the configurations, I find that the number of idle cycle is
is 0. I don't know why the number of idle instruction is 0. Do I miss some
configuration options?
Thanks.
Dan
