Abstract

The invention requests to protect a hybrid wireless optical network-on-chip architecture and a multicast routing algorithm thereof, and the hybrid wireless optical network-on-chip architecture comprises an optical transmission layer, an electric control layer and a wireless transmission layer, and adopts a waveguide structure suitable for Zenneck surface wave transmission and a Walsh coding technology. The corresponding multicast routing algorithm comprises a flexible allocation mechanism of the wireless transmission layer and the optical transmission layer and a multicast routing mechanism based on node distribution in a partition. Compared with a traditional ONoC multicast routing method, the algorithm provided by the invention has better performance in the aspects of average hop count (average time delay) and the like.

Description

technical field [0001] The invention belongs to mobile communication technology, and in particular relates to a hybrid wireless optical on-chip network architecture and a multicast routing algorithm thereof. Background technique [0002] With the advent of the era of big data, technologies such as modern artificial intelligence increasingly rely on high-performance multi-core chips. In the development stage of high-performance multi-core chips, the advantages of optical network on chip (Optical Network on-Chip, ONoC) such as high bandwidth, low power consumption and low delay have solved the difficulty of expanding the system on chip (SoC) in the past. , and disadvantages such as poor reliability of electrical interconnection and high energy consumption in Network on Chip (NoC). However, high-performance computing applications often have the characteristics of high parallelization, which will generate a large amount of interactive data among ONoC nodes, among which multicas...
