Interrupt Handling

An article of manufacture comprising a non-transitory storage medium having instructions stored thereon that, when executed, cause a multi-thread processing environment to:

• interleavingly fetch and issue instructions of a plurality of instruction execution threads for execution by an execution block of the multi-thread processing environment, wherein the plurality of instruction execution threads comprises (i) a subset of the plurality of instruction execution threads and (ii) a first instruction execution thread that is not included in the subset of the plurality of instruction execution threads;
• for each of the plurality of instruction execution threads, provide a corresponding interrupt signal via a corresponding interrupt signal line within the multi-thread processing environment to interrupt fetching and issuing of instructions of the corresponding instruction execution thread, such that a plurality of interrupt signals via a corresponding plurality of interrupt signal lines are provided for the corresponding plurality of instruction execution threads;
• mask the subset of the plurality of instruction execution threads, such that each of the subset of the plurality of instruction threads ignores the corresponding interrupt signal;
• and
• in response to masking the subset of the plurality of instruction execution threads, process, by the first instruction execution thread, one or more interrupt signals corresponding to one or more instruction execution threads of the subset of the plurality of instruction execution threads.
