US 2026/0169712 A1 · RESOURCE REQUIREMENT ANALYSIS AND CONFIGURATION SELECTION FOR VIRTUAL FUNCTIONS IN RECONFIGURABLE PROCESSORS

Abstract

A data processing system for selecting configurations for virtual functions includes a runtime processor coupled to a reconfigurable processor having arrays of coarse-grained reconfigurable units. The runtime processor receives a virtual function request specifying resource requirements including compute requirements, memory requirements, or performance requirements. The runtime processor analyzes the resource requirements to determine a resource profile characterizing the virtual function's computational needs, evaluates available configuration options that provide different array allocations, and selects a configuration that matches the resource profile to configuration capabilities. Selection is based on comparing the resource profile against capability thresholds, where configurations providing one array per virtual function satisfy low requirements, configurations providing two arrays satisfy medium requirements, and configurations providing four arrays satisfy high requirements. The selected configuration optimizes resource utilization while meeting the virtual function's requirements.

Dependent claims

A data processing system, comprising:

a communication link;
a reconfigurable processor comprising a plurality of reconfigurable compute resources and an interface to the communication link;
and
a runtime processor operatively coupled to the communication link,
wherein the runtime processor is configured to:
receive a request for a function context to be executed using the reconfigurable processor, the request specifying one or more resource requirements;
determine, based on the one or more resource requirements, a resource profile for the function context;
evaluate a plurality of candidate allocation configurations that allocate different amounts of the reconfigurable compute resources to the function context;
select an allocation configuration from the plurality of candidate allocation configurations based on whether the allocation configuration satisfies the resource profile and based on availability of unallocated reconfigurable compute resources;
and
configure the interface to the communication link to provide access to reconfigurable compute resources allocated to the function context according to the selected allocation configuration.
