Zusammenfassung:The state of an interrupt is identified. An eligibility value corresponding to the interrupt is generated based on the state of the interrupt. The eligibility value is indicative of whether the interrupt should be processed by a first processing path or a second processing path, the second processing path being lower latency than the first processing path, and the second processing path bypassing operations performed in the first processing path. When an interrupt is received at an assembly language processing system, from a hardware device, the assembly language processing system accesses the eligibility value corresponding to the interrupt and routes the interrupt to the first or second processing path based on the eligibility value.
