Hi David, I am sorry for late response. Here is the configuration I used to simulate my NoC
./build/ARM/gem5.fast configs/example/fs.py --l1d_size=32kB --l1i_size=32kB --num-l2caches 4 --l2_size=1MB --cacheline_size=64 --machine-type=VExpress_GEM5_V1 --kernel /home/khilji/gem5/m5/system/binaries/vmlinux-aarch32 --disk-image /home/khilji/gem5/m5/system/disks/arm-ubuntu-natty-headless.img --dtb-filename /home/khilji/gem5/m5/system/dtb/armv7_gem5_v1_4cpu.dtb --num-cpus=4 --ruby --num-dirs=4 --network=garnet2.0 --topology Mesh_XY --mesh-rows 2 --mem-size 1GB --cpu-clock 1GHz --work-begin-exit-count=1 --work-end-exit-count=1 This is the configuration of 2x2 NoC. Each core has 1GB of memory (DRAM). Total size of memory 4GB. regards, Sharjeel On 2 December 2017 at 02:10, David Kim <[email protected]> wrote: > Thanks Sharjeel, > > So, does each core have its own 1GB memory in your configuration? > > Would you please briefly explain your system configuration? > > > On Fri, Dec 1, 2017 at 1:34 PM, SHARJEEL KHILJI < > [email protected]> wrote: > >> Hi, >> >> I have simulated ARM NoC (4 and 8 cores) with 4 and 8GB with >> VEXPRESS_GEM5_V1 platform.
