Multi-protocol system control device and multi-protocol system control method suitable for industrial-grade application scene and used for physical layer

Abstract

The embodiment of the invention provides a multi-protocol system control device and a multi-protocol system control method for a physical layer, which are suitable for industrial-grade application scenes. The multi-protocol system control device comprises a bus interface selection module and a protocol controller module, the bus interface selection module is connected with a system bus, and the protocol controller module comprises a plurality of bus protocol controllers and a physical layer interface selector. The bus interface selection module is respectively connected with a plurality of bus protocol controllers in the protocol controller module, and the physical layer interface selector interacts with a physical layer and is respectively connected with the plurality of bus protocol controllers; the bus interface selection module is used for receiving a downlink transmission signal sent to a physical layer through a system bus and receiving a protocol control selection signal sent to the physical layer from an upper layer system; the physical layer interface selector is used for receiving a protocol control selection signal sent to a physical layer from an upper layer system, and the multiple bus protocol controllers share the same interface address for the upper layer system.

Description

technical field [0001] The embodiments of the present invention relate to an embedded system, and in particular to a multi-protocol system control device and a multi-protocol system control method for a physical layer applicable to industrial application scenarios. Background technique [0002] The rapid development of embedded processing technology has put forward higher and higher requirements for data processing capabilities and transmission and storage speeds, and has also brought severe challenges to the high-speed interconnection of high-performance embedded systems. [0003] In order to improve the transmission capacity of the bus, the traditional bus is usually implemented by increasing the width of the data bus or increasing the frequency of the bus. For example, the PCI bus supports operating frequencies of 25M, 33M, 50M, and 66M. The PCI-X bus is a bus structure obtained on the basis of the PCI bus structure. It is compatible with the PCI bus in terms of hardware ...
