US Patent 10540219 Reset and error handling in application specific integrated circuits

In one embodiment, a method for reset and error handling comprises identifying at least one queue of a plurality of queues that is subject to a reset, halting fetching of commands from a host that are associated with the at least one queue subject to the reset, halting reallocation of command identifiers of completed commands to commands received from the host that are associated with the plurality of queues, identifying at least one command identifier associated with the at least one queue subject to the reset, updating an error state bitmap to indicate the at least one command identifier as a command in error, resuming reallocation of command identifiers of completed commands after updating the error state bitmap, and resuming fetching of commands from the host that are associated with the at least one queue subject to the reset after resuming reallocation of command identifiers of completed commands.
