In a system constructed by a plurality of integrated circuits, it is possible to appropriately perform interrupt control even in the case where an interrupt has occurred in an integrated circuit in which the function of a CPU is suspended. An interrupt unit of a second integrated circuit outputs an interrupt to at least one of the plurality of image processing units of the second integrated circuit, an image processing unit of the second integrated circuit, to which the interrupt is input, outputs an interrupt to a first integrated circuit, an image processing unit of the first integrated circuit, to which an interrupt from the second integrated circuit is input, outputs an interrupt to an interrupt unit of the first integrated circuit, and the interrupt unit of the first integrated circuit outputs an interrupt to an control unit of the first integrated circuit in accordance with the interrupt being input.

A hot plug method, a host controller, a host, and a PCIe bridge device. The method includes: generating, by a host controller, a first notification packet, where the first notification packet includes hot plug interruption information, and the hot plug interruption information indicates that a first PCIe device is to be hot-plugged; sending, by the host controller, the first notification packet to a host, so that the host performs, according to the first notification packet, a hot plug operation corresponding to the PCIe device; and receiving, by the host controller, a second notification packet sent by the host, and sending the second notification packet to a user equipment controller, to facilitate the user equipment controller to instruct a user to insert or remove the PCIe device, where the second notification packet is for indicating that the hot plug operation corresponding to the PCIe device is completed.

The present disclosure relates to updating a firmware image on a coherent hardware accelerator concurrently with executing operations on the coherent hardware accelerator. According to one embodiment, while executing accelerator-enabled operations on the coherent hardware accelerator, a system stores a firmware update package in a local memory on the coherent hardware accelerator. Once the firmware update package is stored in local memory on the coherent hardware accelerator, the system restarting the coherent hardware accelerator by pausing the execution of at least a first operation initiated on the coherent hardware accelerator and applying the firmware update package to the firmware image on the coherent hardware accelerator. Once the firmware update package is applied to the coherent hardware accelerator, the system resumes the operation on the coherent hardware accelerator.

In one embodiment, a method includes receiving a request from a remote distributed fabric protocol (DFP) system master, using a dedicated processor of a DFP system member, to register local I.sup.2C devices on the DFP system member, and sending an acknowledgement including a list of local I.sup.2C bus devices back to the DFP system master using the dedicated processor of the DFP system member. The acknowledgement present on the DFP system member. In another embodiment, a system includes a local processor, one or more local I.sup.2C bus devices, and a dedicated processor electrically coupled to the local I.sup.2C bus devices. The dedicated processor is configured to route interrupts from the local I.sup.2C bus devices to the local processor, and expose the local I.sup.2C devices to a remote DFP system master by sending details of the local I.sup.2C bus devices to the remote DFP system master.
