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 .
