Stream FIFO insertion in a compilation flow for a heterogeneous multi-core architecture

Abstract:

An example method of implementing an application for a system-on-chip (SOC) having a data processing engine (DPE) array includes obtaining a graph representation of the application, the graph representation including nodes representing kernels of the application and edges representing communication between the kernels, mapping, based on the graph, the kernels onto DPEs of the DPE array and data structures of the kernels onto memory in the DPE array, routing communication channels between DPEs and circuitry of the application configured in programmable logic of the SOC, adding at least one first-in-first-out (FIFO) buffer to at least one of the communication channels, and generating implementation data for programming the SOC to implement the application based on results of the mapping and the routing.
