Abstract: A memory interleaving method includes dividing an access capacity into P partial access capacities based on N pieces of configuration information, where the P partial access capacities have a same size, the N pieces of configuration information are of N memory channels, where one of the N pieces of configuration information corresponds to one memory channel of the N memory channels, each of the N configuration information indicates a quantity of first partial access capacities of the P partial access capacities correspond to a first memory channel, and two partial access capacities correspond to a second memory channel, where a total quantity of memory channels is N, and N is an integer greater than or equal to 2, and mapping the P partial access capacities to the N memory channels.

Abstract: A network-on-chip and a corresponding method are provided. The network-on-chip includes at least one bufferless ring network in at least one dimension of the network-on-chip. At least one bufferless ring network includes multiple routing nodes, and at least one of the multiple routing nodes is a switching node. Two bufferless ring networks in different dimensions may intersect. The two bufferless ring networks exchange data by using switching nodes. A dedicated slot and a public slot are configured in each bufferless ring network. Only one switching node has permission to use a dedicated slot at a same moment in each bufferless ring network, the permission to use the dedicated slot is transferred successively between switching nodes in each bufferless ring network. The permission to use the dedicated slot is transferred after transmission of data in the dedicated slot is completed.

Abstract: A bufferless ring network including at least two nodes and at least two timeslots, the at least two timeslots include a dedicated timeslot, and a first node in the bufferless ring network has use permission for the dedicated timeslot. The first node is configured to, in a state of having the use permission for the dedicated timeslot, detect whether all dedicated timeslots that pass through the first node are available, set a permission switch signal, and cancel the use permission for the dedicated timeslot according to the permission switch signal after detecting that all the dedicated timeslots that pass through the first node are available. A remaining node in the bufferless ring network is configured to obtain the use permission for the dedicated timeslot according to the permission switch signal. The remaining node is a node that needs to use the dedicated timeslot.
