Abstract

The present invention relates to a kind of PCIE Gigabit Ethernet MAC layer controller and driving method, described controller comprises PCI Express Endpoint core, PCI Express interface logic unit, DMA unit, NVM interface, Ethernet GMAC controller, beneficial of the present invention The effect is that a high-performance PCIE Gigabit Ethernet MAC layer controller and a driving method are provided.

Description

technical field [0001] The invention belongs to the field of electrical digital data processing, and in particular relates to a PCIE Gigabit Ethernet MAC layer controller and a driving method. Background technique [0002] There are many ways to realize PCIe to Ethernet, such as the gigabit virtual network card disclosed in Chinese patent CN101719873, which utilizes an FPGA chip to realize the function of a Gigabit Ethernet controller, including an FPGA module and a physical interface transceiver. However, the processing performance of this gigabit virtual network card based on a simple combination of a commercially available FPGA chip and a physical interface transceiver is not ideal. The controller is the core component of the PCIe-to-Ethernet communication function for computing and Ethernet, so a high-performance Gigabit Ethernet MAC layer controller (chip) is currently needed. Contents of the invention [0003] In order to solve the problems of the technologies descr...
