Abstract
This application provides an example system and an example method for chaining DMA transfers from a dataflow graph running across multiple CGRPs. One example first CGRP comprises a first set of coarse-grained reconfigurable units (CGRUs) including a first CGRU, a first external network, a second external network, a first external memory interface (EMI), and first external network shim (Eshim). The first Eshim to receive over the first external network a first transfer (TX) frame of a DMA transfer comprising first frame data from a second CGRP, initiate a memory write of the first frame data to a first memory. The first Eshim to receive a first completion message that indicates the memory write has completed, and to trigger a second DMA transfer of a second TX frame comprising a first subset of the first frame data to a third CGRP utilizing the second external network.
