Method and Apparatus for Dynamic Resource Partition in Simultaneous Multi-Thread Microprocessor

A processor comprising:

• a plurality of instruction queues, the plurality of instruction queues comprising:
• a first queue,
• a second queue, and
• one or more additional queues;
• and
• one or more dispatch units, wherein the dispatch units are configured to:
• provide the first queue with instructions from a first thread among a plurality of simultaneous instruction threads,
• provide the second queue with instructions from a second thread among the plurality of simultaneous instruction threads,
• dynamically assign each of the additional queues to a corresponding thread among the plurality of simultaneous instruction threads, and
• provide each of the additional queues with instructions from the corresponding thread.

A method comprising:

• commencing a time duration of simultaneous processing of a plurality of instruction threads;
• ending the time duration of simultaneous processing;
• and
• during the time duration of simultaneous processing,
• dispatching only instructions from a first thread, among the plurality of instruction threads, to a first queue among a set of instruction queues in a processor,
• dispatching only instructions from a second thread, among the plurality of instruction threads, to a second queue among the set of instruction queues,
• dispatching instructions from the first thread to a third queue among the set of instruction queues, and
• dispatching, based on a status of the first thread, instructions from the second thread to the third queue.
