Abstract
Systems and methods of multi-chip processing with low latency and congestion. In a multi-chip processing system, each chip includes a plurality of clusters arranged in a mesh design. A respective interconnect controller is disposed at the end of each column. The column is linked to a corresponding remote column in the other chip. A share cache controller in the column is paired with a corresponding cache controller in the remote column, the pair of cache controllers are configured to control data caching for a same set of main memory locations. Communications between cross-chip cache controllers are performed within linked columns of clusters via the column-specific inter-chip interconnect controllers.
