Data transmission method and control device between modules

Abstract

The present disclosure provides an inter-module data transmission method, a control module and a function module. The method includes: receiving a read request sent by a first module, where the read request includes an identifier of a second module; finding parameter data of the second module from a parameter storage area according to the identifier; storing the parameter The data is returned to the first module, so that the first module reads the content data of the second module from the data storage area according to the parameter data, breaks the coupling relationship between the functional modules, and the upper and lower modules do not. Directly connected, but adopt the method that all functional modules are connected to the control module, which can meet the system design requirements that cannot be realized by pipeline technology, facilitate the independent debugging of each functional module, and facilitate the external interface to control, modify or add code to the bottom layer. Possibly reduce the number of revisions and modify the content.

Description

technical field [0001] The present disclosure relates to the fields of computer technology and communication technology, and in particular, to a data transmission method between modules, a control device, and a functional module. Background technique [0002] In the current software or hardware development process, pipeline technology is usually used. Pipeline technology is a method of data flow between modules. This method can increase the system frequency, reduce the transmission delay between registers, and ensure that the system runs at a higher clock frequency. [0003] However, this method is only applicable when the data flow is unidirectional, and the output of the previous step is the input of the next step. In this case, the system debugging needs to be completed step by step, and the efficiency is relatively low. Moreover, if each functional module in the system needs to be able to interact, it is difficult to implement such a design. [0004] In addition, in t...

Problems solved by technology

[0003] However, this method is only applicable when the data flow is unidirectional and the output of the previous step is the input of the next step

In this case, system debugging needs to be completed step by step, and the efficiency is relatively low.

Moreover, if each functional module in the system needs to be able to interact, it is difficult to implement such a design.

[0004] Moreover, in the process of logic development, there will always be mutual transfer of data and parameters between functional modules. Once new requirements arise or existing functions need to be modified, it is always inevitable to modify the interface

In this case, developers of different functional modules need extra time to communicate and negotiate to determine the interactive interface of the module. Modifying existing code or adding new functional modules needs to consider the module functions and interfaces of the upper and lower levels.
