Abstract
A programmable interrupt controller arrangement is provided including a multiple number of selectably enabled programmable interrupt controllers along with a multi-channel switch matrix. A scalable number of interrupt sources can be routed to any particular interrupt request line. In addition, from the same architecture, multiple interrupt sources are allowed to share any one of the interrupt request lines. Interrupt signals are routed via the switch matrix under software control. PC/AT compatibility is achieved by selectively disabling certain of the programmable interrupt controllers.
