A network-on-chip Gigabit Ethernet resource node and its working method

Abstract

The invention discloses an on-chip network gigabit Ethernet resource node and a working method thereof. The gigabit Ethernet resource node is composed of an Ethernet module and an Ethernet resource network interface. The aforementioned Ethernet module includes a UDP unpacking and grouping module, a triple-speed Ethernet IP core and a triple-speed Ethernet IP core controller. The UDP unpacking and grouping module is used to perform UDP grouping and unpacking processing on the transmitted data. Triple-speed Ethernet IP core, used for Gigabit Ethernet MAC layer data transmission. The triple-speed Ethernet IP core controller is used to set the working mode of the triple-speed Ethernet IP core. The aforementioned Ethernet resource network interface includes a FIFO module and an RNI controller. The FIFO module is used to store received and sent data. The RNI controller is used for the conversion and forwarding of different protocol data between the network on chip and Gigabit Ethernet. The invention consumes less FPGA resource, has simple hardware circuit and high data transmission rate, and effectively improves the data communication efficiency between NoC and PC.

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...
