Hi, I am trying to use marss with DRAMsim2 to run some spec2006 benchmarks. I have a question about the range of the physical address related to the size of the memory.
I set the memory size to 8092 megabytes to run the benchmarks, I expect the range of the physical address would be 8*1024*1024*1024, that is using the last 33 bits of the physical address to map the memory resource. But when I run the marss simulation, I found the range of the physical address is much smaller which might be within 2*1024*1024*1024. Since when I map the physical address to the memory resource, I would like to map the highest bit to the channel, that is map the 33 bit to the channel ID, the problem is I found the 33 bit always 0 since the range of the physical address in marss is smaller than the memory address. So does anybody has some idea about this? Thanks. Best zhe
