Minimum interrupt latency is largely determined by the interrupt controller circuit and its configuration. They can also affect the jitter in the interrupt latency, which can drastically affect the real-time schedulability of the system. The Intel APIC architecture is well known for producing a huge amount of interrupt latency jitter.
