Assigning Accelerators to Specific Tiles with MultiRoCC
-------------------------------------------------------
Located in ``generators/chipyard/src/main/scala/ConfigFragments.scala`` is a config fragment that provides support for adding RoCC accelerators to specific tiles in your SoC.
Located in ``generators/chipyard/src/main/scala/config/fragments/RoCCFragments.scala`` is a config fragment that provides support for adding RoCC accelerators to specific tiles in your SoC.
Named ``MultiRoCCKey``, this key allows you to attach RoCC accelerators based on the ``hartId`` of the tile.
For example, using this allows you to create a 8 tile system with a RoCC accelerator on only a subset of the tiles.
An example is shown below with two BOOM cores, and one Rocket tile with a RoCC accelerator (Hwacha) attached.

These peripheral devices usually affect the memory map of the SoC, and its top-level IO as well.
To integrate one of these devices in your SoC, you will need to define a custom config fragment with the approriate address for the device using the Rocket Chip parameter system. As an example, for a GPIO device you could add the following config fragment to set the GPIO address to ``0x10012000``. This address is the start address for the GPIO configuration registers.
