Abstract

The invention discloses a wireless on-chip network structuring method. The wireless on-chip network structuring method comprises the steps of: 1) building a wireless interconnection structure; 2) allocating all the wireless sub-channels to wireless links in the wireless interconnection structure, wherein each wireless link includes at least a wireless sub-channel; and then dynamically adjusting the wireless sub-channels of the wireless links based on combined parameters of the wireless links; and 3) realizing transmission of data packets through unicast routing and multicast routing. The wireless on-chip network structuring method can adjust the wireless sub-channels allocated to the wireless links based on a congestion degree of the wireless links, and has a high bandwidth utilization rate for data transmission, low network delay, low power consumption and a high throughput rate.

Description

technical field [0001] The invention relates to the technical field of integrated circuits, in particular to a dynamic wireless on-chip network architecture method. Background technique [0002] The wireless network on chip (Network on Chip, NoC) connection is to connect each network node in the network on chip using wireless connection technology. Compared with wired NoC connections, wireless NoC connections have advantages such as low latency, low power consumption, and strong flexibility, so wireless NoC connections are widely used. Wireless NoC architecture is the most basic link to realize wireless NoC connection, and has a great impact on network throughput, reliability, application layer task mapping, chip area and power consumption. The wireless NoC architecture generally consists of three parts: wireless interconnection model, wireless channel allocation mechanism, and multicast-oriented routing algorithm. The basic unit of the wireless NoC architecture is the net...
