 Check the folder [DRAMSys/gem5/gem5_se/MiBench](DRAMSys/gem5/gem5_se/MiBench) for all applications and configuration files.
 
+### More AARCH64 Apps
+
+Full system simulation files for ARM available in [DRAMSys/gem5/gem5_fs/arm64](DRAMSys/gem5/gem5_fs/arm64).
+
+You can edit [arm64.rcS](DRAMSys/gem5/gem5_fs/arm64/arm64.rcS) to start an application and call *m5 exit* when it finishes.
+
+Edit the paths in [config.ini](DRAMSys/gem5/gem5_fs/arm64/config.ini).
+
+All files required to build DRAMSys_gem5 and execute the simulation (gem5
+library, benchmarks, disk image, etc.) can be obtained with [gem5.TnT].
+
+Start a simulation. Example:
+
+```bash
+dram.sys/build/gem5$ ./DRAMSys_gem5 ../../DRAMSys/library/resources/simulations/rgrsim-gem5-fs.xml ../../DRAMSys/gem5/gem5_fs/arm64/config.ini 1
+```
+
+Optionally, open another terminal or tab and connect to gem5.
+
+```bash
+$ telnet localhost 3456
+```
+
+Note: the port may vary, gem5 prints it during initialization. Example:
+
+```
+system.terminal: Listening for connections on port 3456
+```
