AXI/PCIE bus converting device

Abstract

The present invention discloses an AXI / PCIE bus converting device which is used for data communication between an AXI bus and a PCIE bus. The device includes: an AXI read channel module, an AXI write channel module, a transmission FIFO module, a reception FIFO module, a transmission control module, a reception control module, a Master module, a Slave module, a TX module and an RX module. Compared with the prior art, the device of the present invention can achieve data information interaction between two equipment nodes via the PCIE bus while rapidly and accurately carrying out the data communications between the AXI bus and the PCIE bus; moreover, the device has advantages of simple structure, low cost, and good compatibility.

Description

technical field [0001] The invention relates to a bus conversion device, in particular to an AXI / PCIE bus conversion device, which is used to realize data communication between an AXI bus and a PCIE bus. Background technique [0002] AXI is a new high-performance protocol, which is the most important part of AMBA3.0 proposed by AMBA Corporation, and meets the requirements of ultra-high performance and complex system-on-chip design. It is an on-chip bus for high performance, high bandwidth, and low latency. Its main feature is that address / control and data are separated, and it supports unaligned data transmission. At the same time, it separates read and write data channels, and supports significant transmission access and out-of-order access. [0003] PCIE is the current mainstream bus and interface standard. This new standard replaces the original PCI and AGP buses and becomes the interface standard for a new generation of computer equipment. The PCIE bus adopts a point-t...
