Embodiment 1

[0017] Such as figure 1 As shown, the embodiment of the present invention includes four parts:

[0018] 1. Configuration module: The configuration module CPU selects domestic Loongson 2H, the main frequency can reach above 1GHz, the chip integrates fixed-point processor, floating-point processor, streaming media processing and graphics and image processing functions, and adopts the national operating system to ensure that the software can be independent. Control, configure the RapidIO data switching chip through the I2C bus, and configure the Ethernet switching chip through the PCIE bus.

[0019] 2. RapidIO data exchange module: The RapidIO exchange chip uses IDT's RXS2448. The RXS2448 chip is based on the RapidIO 3.0 specification. The data exchange board has a total of 48 serial channels. Through external configuration, it can be flexibly set to 12×4, 24×2, 24×1 port working mode, the maximum number of ports can be configured as 24, the maximum rate of each channel can reac...

Abstract

The invention relates to the technical field of RapidIO switching and network switching, and in particular relates to a 10-gigabit Ethernet switching and RAPIDIO switching fusion plate based on a domestic CPU. The 10-gigabit Ethernet switching and RAPIDIO switching fusion plate structurally comprises a mainboard and a backplane; a domestic Godson CPU is arranged on the mainboard; the domestic Godson CPU configures a RapidIO data switching chip through an I2C bus, and configures an Ethernet switching chip through a PCIE bus; the mainboard is connected to a power supply through a VPX connector of the backplane; and the mainboard externally provides 18 4X RapidIO interfaces and 18 10-gigabit Ethernet SerDes interfaces through the backplane, and is in cascade connection with the backplane through the VPX connector. By means of the 10-gigabit Ethernet switching and RAPIDIO switching fusion plate based on the domestic CPU disclosed by the invention, the domestic Godson can be used as the CPU; and thus, the purposes of satisfying 10-gigabit Ethernet switching and also satisfying RapidIO switching can be achieved.

Description

technical field [0001] The invention relates to the technical field of RapidIO exchange and network exchange, in particular to a 10 Gigabit Ethernet exchange and RAPIDIO exchange fusion board based on a domestic CPU. Background technique [0002] RapidIO is a high-performance, low-pin-count, packet-based interconnection architecture pioneered by companies such as Motorola and Mercury. It is an open interconnection architecture designed to meet and future high-performance embedded system requirements. even technical standards. RapidIO is mainly used in the internal interconnection of embedded systems, supports chip-to-chip, board-to-board communication, and can be used as the backplane (Backplane) connection of embedded devices. [0003] Now there are simple 10 Gigabit Ethernet switching boards and RapidIO-based switching boards on the market, but in many application scenarios, both 10 Gigabit Ethernet switching and RapidIO switching are required, and there is currently no s...
