One embodiment relates to a method for providing interrupt lookups for a plurality of interrupt status vectors stored in random access memory on an integrated circuit. The plurality of interrupt status vectors in the random access memory are scanned to find activated interrupt status vectors that changed from null to non-null and dismissed interrupt status vectors that changed from non-null to null. A linked search list is maintained in the random access memory by inserting memory addresses of the activated interrupt status vectors into the linked search list and removing memory addresses of the dismissed interrupt status vectors from the linked search list. Interrupt status vectors for currently active interrupts are looked-up by transversing the linked search list in the random access memory. Other embodiments, aspects and features are also disclosed herein."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Methods and apparatus for rapid interrupt lookups","description":"The present disclosure provides methods and apparatus for rapid interrupt look-ups for interrupts stored in memory.
