Abstract

A system, such as an AMBA based system, wherein an interrupt controller is coupled directly to a processor, thereby providing that the processor can access the interrupt controller without having to access a system bus. Specifically, the interrupt controller may be coupled to a port of the processor, such as a tightly coupled memory (TCM) port or a coprocessor port of the processor. The interrupt controller may be coupled to the TCM port along with SRAM.
