Gigabit Ethernet resource node for NoC (Network on Chip) and working method thereof

Abstract

The invention discloses a gigabit Ethernet resource node for an NoC (Network on Chip) and a working method thereof. The gigabit Ethernet resource node consists of an Ethernet module and an Ethernet resource network interface. The Ethernet module comprises a UDP (User Datagram Protocol) unpacking and packing module, a triple speed Ethernet IP (Intellectual Property) core and a triple speed Ethernet IP core controller. The UDP unpacking and packing module is used for performing UDP packing and unpacking processing on transmitted data, and the triple speed Ethernet IP core is used for data transmission of an MAC (Media Access Control) layer of the gigabit Ethernet. The triple speed Ethernet IP core controller is used for setting a working mode of the triple speed Ethernet IP core. The Ethernet resource network interface comprises an FIFO (First Input First Output) module and an RNI (Resource Network Interface) controller. The FIFO module is used for storing received data and sent data. The RNI controller is used for conversion and forwarding of data of different protocols between the NoC and the gigabit Ethernet. The gigabit Ethernet resource node consumes less FPGA resource, a hardware circuit is simple, a data transmission rate is high, and communication efficiency of the data between the NoC and a PC is effectively improved.

Description

technical field [0001] The invention relates to the field of on-chip network technology, in particular to an on-chip network Gigabit Ethernet resource node and a working method thereof. Background technique [0002] Based on the network on chip (NoC) developed from computer network technology, the communication architecture composed of routing nodes realizes data routing and packet exchange, and resource nodes realize various functionalities through one-to-one communication with routing nodes. The interactive communication of resource nodes in the communication framework. At present, the data communication method between the network on chip and the PC is relatively simple, and there are few studies. Improving the communication rate between the two is an urgent problem that NoC needs to solve for wider applications. [0003] To realize the functions of Ethernet in the network on chip, it is first necessary to integrate the NoC system with the TCP / IP protocol. One of the com...
