US Patent 11768626 Stencil data access from tile memory

A reconfigurable compute fabric of a system can include multiple nodes, and each node can include multiple, communicatively coupled tiles with respective processing and storage elements. In an example, a tile-based processor can be configured to perform operations comprising receiving a first stencil that defines input data for a first operation. The stencil can have a height corresponding to N rows in a main memory and a stencil width corresponding to M columns in the main memory. The processor can perform operations comprising establishing N buffers in a tile memory, each buffer having M buffer elements, and populating the M buffer elements of the N buffers using respective information, defined by the first stencil, from the main memory. Tile-based stencil operations can use information from the N buffers and provide compute results in an output array.
