## DRAMSys with gem5
Install gem5 by following the instructions in the [gem5 documentation](https://www.gem5.org/documentation/general_docs/building). In order to allow a coupling without running into problems we recommend to use **commit a470ef5**. Optionally, use the scripts from [gem5.TnT] to install gem5, build it, get some benchmark programs and learn more about gem5.

In order to understand the SystemC coupling with gem5 it is recommended to read the documentation in the gem5 repository *util/tlm/README* and [1].

### DRAMSys with gem5 Elastic Traces
To understand elastic traces and their generation, study the [gem5 wiki](https://www.gem5.org/documentation/general_docs/cpu_models/TraceCPU) and the paper [2]. Some predefined configs are stored [here](DRAMSys/gem5/configs) and the related
python files are stored [here](DRAMSys/gem5/examples). This is an example for running an elastic trace:
```bash
./DRAMSys_gem5 ../../DRAMSys/library/resources/simulations/ddr3-example.json ../../DRAMSys/gem5/configs/singleElasticTraceReplay.ini 1
```
An overview of the architecture being simulated is presented below:
![arch](images/singleElasticTraceReplay.png)
Note that the address offset is usually zero for elastic traces.
Another example with L2 cache:
```bash
./DRAMSys_gem5 ../../DRAMSys/library/resources/simulations/ddr3-example.json ../../DRAMSys/gem5/configs/singleElasticTraceReplayWithL2.ini 1
```
If two elastic traces should be used run the simulation with the following example:
```
./DRAMSys_gem5 ../../DRAMSys/library/resources/simulations/ddr3-example.json ../../DRAMSys/gem5/configs/dualElasticTraceReplay.ini 2
```
An overview of the architcture being simulated is presented below:
![arch](images/dualElasticTraceReplay.png)
For more sophisticated setups, even with L2 caches the proper *.ini* file should be created.
