Abstract

Provided are a method and device for controlling the traffic of a network-on-chip (NoC). The method comprises: predicting a traffic change value of an NoC within a future set time using a back propagation (BP) neural network; acquiring a performance parameter of a central processing unit (CPU) in the NoC; and controlling the current traffic of the NoC according to the traffic change value and the performance parameter. By means of the technical solution in the embodiments of the present invention, it can be guaranteed that the processing capability of a CPU matches the traffic change of an NoC, thereby achieving the effects of controlling the network byte sequence traffic of the NoC and avoiding the traffic congestion.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a flow control method and device for a network on chip (NoC). Background technique [0002] Network-on-Chip (NoC for short), as an on-chip communication network, can be applied to a System-on-Chip (SoC for short), such as a single-chip multi-processor (Chip Multi-Processors, Abbreviated as CMP) and so on. NoC-based systems are better suited to globally asynchronous, locally synchronous clock mechanisms used in future complex multi-core SoC designs. The NoC framework is mainly based on electronic and optical technologies, which are called Electrical Network-on-Chip (ENoC for short) and Optical Network-on-Chip (ONoC for short) respectively. In NoC, the commonly used and most suitable network structure is a packet-switched direct network, that is, each node is connected to adjacent nodes through a bidirectional channel. In addition, in order to facilitate expansion, the co...
