Per instance core control in accelerated computing environments

Abstract:

Controlling functionality of a core on a per-instance basis can include implementing, within an accelerator, an instance of a core by configuring the accelerator using configuration data, receiving, within the instance of the core, encrypted authorization data for the instance of the core, generating, using control circuitry of the instance of the core, decrypted authorization data for the instance of the core by decrypting the encrypted authorization data using a core instance identifier stored in a first control register of the instance of the core, and writing the decrypted authorization data to a second control register in the instance of the core, wherein the instance of the core enables core functionality therein based on the decrypted authorization data in the second control register.
