CacheSim

This is CacheSim, a cache simulator developed by Insomniac Games. In its current form it simulates an AMD Jaguar cache configuration. It requires a 64-bit Windows machine to work. It has been tested on Windows 8, 8.1 and 10, but may require tweaking to run on your particular version of Windows.

For more information on how CacheSim was developed and how it works internally, you can check out this GDC 2017 slide deck.

The talk is available on the GDC vault with full video as well.

Getting the Source

  1. Clone this project
  2. git submodule init
  3. git submodule update

The latter two commands will fetch Google Test which is required to build the unit tests.

Build Instructions

You'll need the following:

  • Visual Studio 2015
  • CMake
  • Qt 5.7 or later

To build CacheSim:

  1. Launch the Qt command line environment
  2. CD into the CacheSim directory
  3. Create a build directory: mkdir build
  4. Change into this build directory: cd build
  5. Run cmake -G "Visual Studio 14 2015 Win64" ..
  6. start CacheSim.sln to open the solution and build in Visual Studio

Note that the only supported build configuration is 64-bit (x64). Bug reports about missing 32-bit support will be ignored.
