Abstract
Methods, systems, and apparatuses provide support for allowing thread forward progress in a processing system and that improves quality of service. One system includes a processor; a bus coupled to the processor; a memory coupled to the processor via the bus; and a floating point unit coupled to the processor via the bus, wherein floating point unit comprises hardware control logic operative to: store for each thread, by a scheduler of the floating point unit, a counter; increase, by the scheduler, a value of the counter for each thread corresponding to a thread when at least one source ready operation exist for the thread; compare, by the scheduler, the value of the counter to a predetermined threshold; and make other threads ineligible to be picked by the scheduler when the counter is greater than or equal to the predetermined threshold.
