Abstract
A method of controlling a data processor to perform data processing operations is disclosed in which a host processor prepares one or more queue(s) of operations for execution by the data processor. When an error is encountered in the processing of an operation for one of the one or more queue(s), a queue can be set into an error state in which instructions that may have a data dependency on another operation are not executed. The host processor includes in the queues error barrier instructions that divide the respective queues into sets of operations between which there are no data processing dependencies. An error state for a queue can thus be cleared when its processing reaches the next error barrier instruction in the queue.
