Hello All, I am working with the DRAM model for my simulations in SE mode. I use the default configuration in PhysicalMemory.py for the RAS, CAS, ACT etc times. It seems when the DRAMMemory object is initialized the cas_lat, act_lat etc timing parameters are set in ps or the number of simulation ticks. These variables are then used by the calculateLatency function to estimate the latency of the memory access in terms of simulation ticks. However, before returning this latency value, the calculateLatency function multiplies it with cpu_ratio (defined as ratio of CPU and memory bus frequency; set to 5 by default). This looks confusing and unintuitive, since all the prior calculations in the function are done in terms of simulation ticks only, so how does cpu_ratio come into the picture?
Can anyone please provide insights here into what could be the possible reason for doing so? Thanks in advance, -Gaurav _______________________________________________ m5-users mailing list m5-users@m5sim.org http://m5sim.org/cgi-bin/mailman/listinfo/m5-users
