Network-on-chip system for layered MCC

Abstract

The invention discloses a network-on-chip system for a layered MCC. Computing resource units are connected with router nodes to provide resources such as data of the router nodes during computing; the router nodes turn into an annular topological structure through coordination connection to form into a first layer for a MCC network-on-chip system; the first layer is used for enhancing local characteristics and performance of the network-on-chip system; and the router nodes and super nodes are combined to form into the super nodes which are used for forming into a two-dimensional Mesh topological structure which is simple in structure and low in network cost and has planarity, regularity and good expansibility. According to a MCC interconnection network, a certainty shortest path router is utilized; average communication delay, average handling capacity and link utilization rate are analyzed and simulated; a result indicates that the MCC is good in network performance in light loading or local communication; FPGA indicates that the MCC interconnection network which is simple and efficient is low in network cost; and the network performance and cost are well balanced.

Description

technical field [0001] The invention belongs to the field of network technology, in particular to a layered MCC on-chip network system. Background technique [0002] At present, most of the research and design of network-on-chip NoC refer to the static network structure in parallel computer architecture, including regular and irregular structures. Most NoCs adopt Mesh and Torus regular structures, and a few NoCs adopt fat tree structures, octagonal structures, Spidergon structures, ring structures, hierarchical ring structures, Rgrid structures, GP(2m,1) structures, and irregular structures changed from regular structures wait. The node connection degree of the planar Mesh (Torus is non-planar) topology structure is 4, and the connection degree is low, which makes the implementation cost of the NoC router node higher.
