Abstract: An integrated circuit can include a data processing engine (DPE) array having a plurality of tiles. The plurality of tiles can include a plurality of DPE tiles, wherein each DPE tile includes a stream switch, a core configured to perform operations, and a memory module. The plurality of tiles can include a plurality of memory tiles, wherein each memory tile includes a stream switch, a direct memory access (DMA) engine, and a random-access memory. The DMA engine of each memory tile may be configured to access the random-access memory within the same memory tile and the random-access memory of at least one other memory tile. Selected ones of the plurality of DPE tiles may be configured to access selected ones of the plurality of memory tiles via the stream switches.

Abstract: An apparatus includes a data processing array having a plurality of array tiles. Each array tile can include a random-access memory (RAM) having a local memory interface accessible by circuitry within the array tile and an adjacent memory interface accessible by circuitry disposed within an adjacent array tile. Each adjacent memory interface of each array tile can include isolation logic that is programmable to allow the circuitry disposed within the adjacent array tile to access the RAM or prevent the circuitry disposed within the adjacent array tile from accessing the RAM. The data processing array can be subdivided into a plurality of partitions wherein the isolation logic of the adjacent memory interfaces is programmed to prevent array tiles from accessing RAMs across a boundary between the plurality of partitions.
