A Communication Mechanism of Wireless Network-on-a-Chip Based on Two-dimensional Grid

Abstract

The invention discloses a communication mechanism of a wireless network-on-chip based on a two-dimensional grid. The communication mechanism comprises the steps that 1, a zone bit is added in data packet header routing information to mark the transmitting mode of a data packet; and 2, whether the transmitted data packet is a long distance data packet or a short distance data packet is judged, and different routing paths are arranged for the data packet to transmit the data packet. The bearing capacity of the wireless resource in the wireless network-on-chip for data load can be enhanced and the communication delay of the network can be reduced.

Description

technical field [0001] The invention belongs to the application technical field of integrated circuit chip design, in particular a two-dimensional grid-based wireless on-chip network communication mechanism proposed for solving the problem of network performance degradation caused by wireless interface congestion in the wireless on-chip network. Background technique [0002] Network-on-Chip (Network-on-Chip) has gradually become an effective structure for realizing on-chip multi-core, but as the number of integrated cores in the network increases, the communication delay and power consumption between nodes in the network become higher and higher, By inserting long-distance links in the network, the average number of hops between nodes can be reduced without reducing the network scale, thereby reducing the communication delay of the entire network. However, the inserted long-distance link is still a metal link. It is pointed out in ITRS that in the long run, improving the met...
