METHODS FOR RECONFIGURING A STORAGE CONTROLLER WHEN CONTROL LOGIC FAILS AND APPARATUSES USING THE SAME

摘要

A method for processing return entities associated with multiple requests in a single ISR (Interrupt Service Routine) thread, performed by one core of a processing unit of a host device, is introduced. Entities are removed from a queue, which are associated with commands issued to a storage device, and the removed entities are processed until a condition is satisfied.

1. A method for reconfiguring a storage controller when control logic fails, performed by a processing unit, comprising:
determining that the storage controller has failed; suspending an access of the storage controller; directing reconfiguration control logic of a fixed region of the storage controller to reprogram a whole reconfigurable region of the storage controller; and resuming the access of the storage controller.
