Routing 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 including determining 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, building a routing graph of all possible routing choices in the DPE array for communicate channels between DPEs and circuitry of the application configured in programmable logic of the SOC, adding constraints to the routing graph based on an architecture of the DPE array, routing communication channels between DPEs and circuitry of the application configured in programmable logic of the SOC based on the routing graph, and generating implementation data for programming the SOC to implement the application based on results of the mapping and the routing.
