Abstract: Systems, apparatuses, and methods for implementing scheduler queue assignment burst mode are disclosed. A scheduler queue assignment unit receives a dispatch packet with a plurality of operations from a decode unit in each clock cycle. The scheduler queue assignment unit determines if the number of operations in the dispatch packet for any class of operations is greater than a corresponding threshold for dispatching to the scheduler queues in a single cycle. If the number of operations for a given class is greater than the corresponding threshold, and if a burst mode counter is less than a burst mode window threshold, the scheduler queue assignment unit dispatches the extra number of operations for the given class in a single cycle. By operating in burst mode for a given operation class during a small number of cycles, processor throughput can be increased without starving the processor of other operation classes.
