Embodiment Construction

[0050] Hereinafter, the present invention will be described in detail through specific embodiments in conjunction with the accompanying drawings.

[0051] Below to figure 1 The typical 4*4 two-dimensional grid structure network-on-chip is shown as an example to describe the present invention in detail.

[0052] figure 2 It is a fault-tolerant network-on-chip system with global communication transaction management capability built on a 4×4 two-dimensional grid structure network-on-chip. Such as figure 2 As shown, each router R is connected to a network monitor through a dedicated bus in addition to being connected to four neighboring routers and a local IP core c. This dedicated bus is used to transmit network status and routing path information, using Triple Module Redundancy (TMR), which uses 3 wires and a voting circuit to ensure the reliability of information transmission, such as image 3 As shown, the output data state f is determined by the three input data states ...

Abstract

The invention discloses a fault-tolerant on-chip network system with the global communication service management capability. In the fault-tolerant on-chip network system, a network monitor and fault-tolerant routers serve as cores and are connected mutually through special buses to form the fault-tolerant on-chip network system. The invention further discloses a route distribution method and a network data transmission method applied to the fault-tolerant on-chip network system. Through the fault-tolerant on-chip network system, the route distribution method and the network data transmission method, the global network state can be monitored, network congestion and fault links can be located and recognized, data retransmission can be conducted timely, transient faults can be avoided, congestion and permanent fault links can be avoided through rerouting, the fault-tolerant capability of an on-chip network is effectively improved, and meanwhile the network data transmission performance at a high communication load is optimized and improved.

Description

technical field [0001] The invention belongs to the field of on-chip network system design, and in particular relates to a fault-tolerant on-chip network system with global communication transaction management capabilities and a method applied to the system. Background technique [0002] Network on Chip (Network on Chip, NoC) provides an efficient, reliable, and flexible communication architecture for the interconnection between IP cores by constructing a micro-network based on data message exchange on a single chip, and has become a solution to complex system-on-chip design. An efficient solution to the global interconnection and communication problem. A typical network-on-chip system such as figure 1 As shown, each router (Router, R) is connected to four adjacent routers, and is connected to a functional IP core through a network interface (Network Interface, NI). The interconnection channels between routers and between routers and functional IP cores are composed of two...
