Abstract: In a memory management method, a first processor in a system is associated with at least two different types of memory media. After obtaining a memory allocation request, the first processor fully considers physical attributes such as a memory capacity, an access latency, a cost, or a service life of the multiple different types of memory media in the system when allocating a memory resource to a running application. The processor selects a to-be-allocated memory resource from the multiple different types of memory media based on a low access latency of the first processor accessing an allocated memory resource.

Abstract: In a data processing method implemented in a hierarchical memory system including a first memory medium and a second memory medium of different types, a processor obtains data distribution in the hierarchical memory system. The processor determines a data migration manner based on the data distribution, where the data migration manner is for implementing migration processing on a migration data set between the different memory media based on the data distribution. The processor then performs migration processing on the migration data set based on the migration manner.

Abstract: A method for controlling an internal memory bandwidth includes after obtaining a bandwidth required by a to-be-accessed internal memory medium, a processor in a system obtains an occupancy rate of an internal memory bandwidth of the to-be-accessed internal memory medium. If determining, based on the occupancy rate of the internal memory bandwidth, that the to-be-accessed internal memory medium cannot satisfy a bandwidth requirement, the processor adjusts, under an indication of a bandwidth adjustment policy, the occupancy rate of the internal memory bandwidth based on a factor that affects the occupancy rate of the internal memory bandwidth of the to-be-accessed internal memory medium, and the processor uses a first bandwidth that satisfies the bandwidth requirement in an adjusted remaining bandwidth of the to-be-accessed internal memory medium.

Abstract: 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.
