Description

兼容两种协议的多通道切换控制电路及控制方法Multi-channel switching control circuit and control method compatible with two protocols

技术领域technical field

本发明涉及一种多通道切换控制电路及控制方法,尤其涉及一种兼容两种协议的多通道切换控制电路及控制方法。The invention relates to a multi-channel switching control circuit and a control method, in particular to a multi-channel switching control circuit and a control method compatible with two protocols.

背景技术Background technique

集成电路设计中经常需要对多通道进行切换,所以会用到相应的切换控制电路。目前,多通道切换控制电路主要有一键脉冲控制电路模块和独立引脚的功能控制电路模块,现有的多通道切换控制电路都只选择其中一种电路模块,所以都只有一种协议。In integrated circuit design, it is often necessary to switch multiple channels, so the corresponding switching control circuit will be used. At present, the multi-channel switching control circuit mainly has a key pulse control circuit module and a function control circuit module with independent pins. Existing multi-channel switching control circuits only select one of the circuit modules, so there is only one protocol.

随着现代电子信息产业的蓬勃发展,电子产品向多元化方向衍变,只有一种协议的控制方法在系统设计中缺少了设计的灵活性,也不利于资源的有效利用,在现代新型电子系统的设计中存在很大局限性。具体表现为:独立引脚的功能控制电路模块因为其需要单独的控制I/O进行控制,会给系统设计造成I/O资源的浪费,在主控的I/O资源紧缺的情况下不利于资源的有效应用与合理分配;一键脉冲控制电路模块因为其复用的特性,会让系统的设计更复杂并增加设计的难度,在I/O资源丰富的设计中会造成设计成本的浪费,并降低系统的可靠性。With the vigorous development of the modern electronic information industry, electronic products are evolving in a diversified direction. Only one protocol control method lacks design flexibility in system design and is not conducive to the effective use of resources. In the modern new electronic system There are significant limitations in the design. The specific performance is: the function control circuit module with independent pins requires a separate control I/O for control, which will cause a waste of I/O resources in the system design, which is not conducive to the shortage of I/O resources for the main control. Effective application and reasonable allocation of resources; the one-key pulse control circuit module will make the system design more complicated and increase the difficulty of the design because of its multiplexing characteristics, which will cause waste of design cost in the design with rich I/O resources. And reduce the reliability of the system.
