US 2026/0169713 A1 · RESOURCE ALLOCATION FOR VIRTUAL FUNCTIONS IN MULTI-DIE RECONFIGURABLE PROCESSORS

Abstract

A system for allocating reconfigurable processor resources to virtual functions includes a runtime processor coupled to a multi-die reconfigurable processor via a communication link. The reconfigurable processor comprises first and second dies arranged in a package, each die having arrays of coarse-grained reconfigurable units. The runtime processor receives resource allocation requests for virtual functions, determines resource requirements for each virtual function including number of arrays and memory capacity, evaluates available resources across the first and second dies, and allocates arrays from the first die, the second die, or both dies to each virtual function based on the resource requirements and available resources. The runtime processor configures communication link interfaces to provide the allocated arrays to virtual function drivers, enabling efficient multi-tenant operation of the reconfigurable processor with optimized resource utilization and isolation between virtual functions.

Dependent claims

A system for providing logically isolated access to resources of a reconfigurable processor, the system comprising:

(a) a reconfigurable processor comprising one or more dies within a package, each die comprising reconfigurable compute resources and an interface configured to communicate over a communication link;
and
(b) a runtime processor coupled to the communication link,
wherein the runtime processor is configured to:
(i) receive a request to create or configure a function context for use by a driver;
(ii) select, from an available pool, a subset of the reconfigurable compute resources to associate with the function context;
(iii) configure at least one of (A) one or more die interfaces or (B) an access-control configuration to provide the driver with logically isolated access to the subset of the reconfigurable compute resources associated with the function context;
(iv) maintain allocation state that maps the function context to the subset of the reconfigurable compute resources;
and
(v) enforce, based on the allocation state, at least one access restriction that limits access by the driver to resources outside the subset.
