Abstract
A data processing system configured to execute a plurality of threads includes a plurality of domains and a plurality of domain interrupt controller circuits, each domain interrupt controller corresponding to a domain of the plurality of domains. Each domain interrupt controller includes an interrupt selection circuit configured to select an interrupt request from a set of interrupt requests received by the interrupt selection circuit and determine an interrupt vector for the selected interrupt request, a programmable domain-thread storage circuit configured to store an enable indicator corresponding to each thread of the plurality of threads in which the enable indicator for each corresponding thread indicates whether or not the corresponding domain is permitted to route interrupt vectors to the corresponding thread, and a routing circuit configured to route the interrupt vector to a selected thread of the plurality of threads which is selected based at least in part on the enable indicators.
