Systems and methods for implementing directional operand broadcast and multiply-accumulate execution using a configurable patch mesh in a multi-core processing array of an integrated circuit

Abstract

A technique is disclosed for operand propagation and accumulation within a processing array of an integrated circuit using overlapping patch regions. The system includes an interconnecting processing patch defined over a rectilinear subset of processing elements, with an origin processing element broadcasting operand data to the remaining elements in a directionally constrained, time-staggered wavefront pattern. A logical processing patch is separately defined over a second rectilinear subset of processing elements. The interconnecting processing patch and the logical processing patch partially overlap to form an interconnecting patch mesh comprising a common set of processing elements. Operand data is propagated from the origin of the interconnecting patch to the common processing elements within the patch mesh, enabling operand handoff or accumulation across patch boundaries. The architecture supports fine-grained, localized data movement and patch-level execution coordination across a mesh of processing elements to optimize compute reuse, operand locality, and execution throughput.
