Hi Xiaokang. 1. All of those CPU models will be able to execute the same set of instructions since they use the same instruction implementations. The HPI CPU is really just the O3CPU with some of the configuration set a certain way, I think. 2. I don't know for sure, but there are some constants related to it in src/arch/arm/regs/vec.hh. 3. SE mode vs FS mode isn't really related to the benchmark's size, it's more about how much the benchmark or other program depends on the operating system, and how complex its interactions are. Also, SE mode is usually a little simpler to set up since you don't need to build a disk image, get the OS set up, etc, but FS is more realistic since it actually simulates the OS components and hardware.
