Abstract
The present disclosure provides a Peripheral Component Interconnect Express (PCIe) controller for a PCIe endpoint device. The PCIe controller includes: a PCIe link interface configured to receive an interrupt request message, wherein the interrupt request message is a message write transaction PCIe transport layer packet (TLP) including an address associated with the PCIe endpoint device and a data value including interrupt information; an interrupt request trigger register configured to receive the data value; a plurality of interrupt lines; and a decode logic circuit connected to the interrupt request trigger register and the plurality of interrupt lines, the decode logic circuit configured to automatically decode a plurality of data bits of the data value when received in the interrupt request trigger register and generate an interrupt signal and provide the interrupt signal on one of the plurality of interrupt lines to an interrupt handling circuit.
