Network-on-Chip with Network Coding, Network Topology and Routing Methods

Abstract

This application discloses an on-chip network with network coding function, network topology and routing method. The coding sub-module codes multiple received packet data, and the coded data is forwarded by the intermediate routing node in a multicast manner. , the decoding sub-module decodes the received data according to the known information, and restores the original data; the network coding module realizes the compression of packet data, thereby increasing the amount of information carried by the data transmitted by the network, and solving the problem of how to achieve network transmission capacity Limit problems, and facilitate network scale expansion, and the network coding function can reduce network load and improve network performance.

Description

technical field [0001] The application relates to the field of communication technology, and specifically relates to an on-chip network with network coding function, network topology and routing method used in the field of scientific research. Background technique [0002] With the development of integrated circuit technology, the shortcomings of bus-structured system-on-chip are becoming more and more prominent. In order to overcome these shortcomings, network-on-chip (NoC) emerges as the times require. The network on chip adopts a reasonable topology structure and introduces routing and switching theory, so its parallel communication characteristics can meet the needs of future development. For example, in 2012, Intel's latest on-chip network processor Xeon Phi 5110P integrated 60 IP cores with 22nm process 3D transistors, operating frequency up to 1.053GHz, and achieved double-precision peak performance up to 1.011TFlops, becoming a high-performance computing platform. n...

Problems solved by technology

[0004] Many kinds of multicast packets may arrive at an intermediate router at the same time. Since ordinary routing nodes can only forward one kind of multicast packets at a time, other multicast packets need to wait in line, which reduces the throughput of the network, and cannot be achieved by the "maximum flow rate". The maximum transmission capacity determined by the minimum cut theorem
