TileLink and Diplomacy Reference
|
|
================================
|
|
|
|
TileLink is the cache coherence and memory protocol used by RocketChip and
|
|
other Chipyard generators. It is how different modules like caches, memories,
|
|
peripherals, and DMA devices communicate with each other.
|
|
|
|
RocketChip's TileLink implementation is built on top of Diplomacy, a framework
|
|
for exchanging configuration information among Chisel generators in a two-phase
|
|
elaboration scheme. For a detailed explanation of Diplomacy, see `the paper
|
|
by Cook, Terpstra, and Lee <https://carrv.github.io/2017/papers/cook-diplomacy-carrv2017.pdf>`_.
|
|
|
|
A brief overview of how to connect simple TileLink widgets can be found
|
|
in the :ref:`mmio-accelerators` section. This section will provide a
|
|
detailed reference for the TileLink and Diplomacy functionality provided by
|
|
RocketChip.
|
|
|
|
A detailed specification of the TileLink 1.7 protocol can be found on the
|
|
`SiFive website <https://sifive.cdn.prismic.io/sifive%2F57f93ecf-2c42-46f7-9818-bcdd7d39400a_tilelink-spec-1.7.1.pdf>`_.
