thanks Mahmood ,actually I decreased the i-cache size to 512Byte ,miss rate changed but didn't differ a lot.
the command line in gem5 : ./build/X86/gem5.fast configs/example/fs.py --script=scirpts/blackscholes_1c_simsmall.rcS --caches --l2cache --l1i_size=1kB --l1d_size=1kB --l1i_assoc=2 --cacheline_size=64 and I have used Texas disk image. with this configuration miss rate is 16% ( the sum of "system.cpu.icache.overall_miss_rate:: total" in 4 separate sets of statistics in stat.txt file. ) also I ran blackscholes on sniper simulator for the same I-cache configuration and the miss rate was about 33% . If anyone has experienced the same issue , I would really appreciate to let me know about the correctness of miss rate results. thanks .
