Abstract: A device may include a processor system and an array of data processing engines (DPEs) communicatively coupled to the processor system. Each of the DPEs includes a core and a DPE interconnect. The processor system is configured to transmit configuration data to the array of DPEs, and each of the DPEs is independently configurable based on the configuration data received at the respective DPE via the DPE interconnect of the respective DPE. The array of DPEs enable, without modifying operation of a first kernel of a first subset of the DPEs of the array of DPEs, reconfiguration of a second subset of the DPEs of the array of DPEs.

Abstract: Examples herein describe techniques for transferring data between data processing engines in an array using shared memory. In one embodiment, certain engines in the array have connections to the memory in neighboring engines. For example, each engine may have its own assigned memory module which can be accessed directly (e.g., without using a streaming or memory mapped interconnect). In addition, the surrounding engines (referred to herein as the neighboring engines) may also include direct connections to the memory module. Using these direct connections, the cores can load and/or store data in the neighboring memory modules.

Abstract: An example data processing engine (DPE) for a DPE array in an integrated circuit (IC) includes: a core; a memory including a data memory and a program memory, the program memory coupled to the core, the data memory coupled to the core and including at least one connection to a respective at least one additional core external to the DPE; support circuitry including hardware synchronization circuitry and direct memory access (DMA) circuitry each coupled to the data memory; streaming interconnect coupled to the DMA circuitry and the core; and memory-mapped interconnect coupled to the core, the memory, and the support circuitry.

Abstract: Examples herein describe techniques for communicating between data processing engines in an array of data processing engines. In one embodiment, the array is a 2D array where each of the DPEs includes one or more cores. In addition to the cores, the data processing engines can include streaming interconnects which transmit streaming data using two different modes: circuit switching and packet switching. Circuit switching establishes reserved point-to-point communication paths between endpoints in the interconnect which routes data in a deterministic manner. Packet switching, in contrast, transmits streaming data that includes headers for routing data within the interconnect in a non-deterministic manner. In one embodiment, the streaming interconnects can have one or more ports configured to perform circuit switching and one or more ports configured to perform packet switching.
