Abstract
In an embodiment, a system includes at least one peripheral device, an interrupt controller, a memory controller, at least one CPU, and an interrupt message circuit coupled to the peripheral device. The interrupt message circuit may be coupled to receive the interrupt signal from the peripheral device, and may be configured to generate an interrupt message for transmission on a communication fabric. In some embodiments, there may be multiple peripherals which have independent paths through the fabric for memory operations to the memory controller. Each such peripheral may be coupled to an instance of the interrupt message circuit. In an embodiment, the interrupt is level sensitive. The interrupt message circuit may be configured to transmit interrupt set messages an interrupt clear messages to the interrupt controller, to indicate the levels.
