An asynchronous communication controller and its control method

Abstract

The invention principally relates to an asynchronous communication controller and its control method, particularly to a communication controller using a data frame form to perform information communication because various application environments can be configured, and its data transmission and communication control method. A kind of asynchronous communication controller, uses configurable data storage unit, is a rapid asynchronous communication of multi-frame data packets supporting single frame data pack and adapt for various communication modes, which has main features that it includes a data packet storage unit (2) communicated to a CPU (1), a control unit (3) is respectively communicated with the data packet storage unit (2), a sending unit (4), and a receiving unit (5), and the sending unit (4) is communicated to a receiving unit (5) through a communication physical channel (6). The invention has advantage that: compared with the existing technology, the invention solves the problems of the existing communication controller and control method thereof, such as single communication corresponding mode, single adapting to the application environment, and incapability of no dynamic change.

Description

Technical field: [0001] The present invention mainly relates to an asynchronous communication controller and a control method thereof, in particular to a communication controller capable of performing information communication in the form of a data frame and a data transmission and communication control method that can be configured in response to various application environments. Background technique: [0002] The existing communication controllers and communication methods mainly have the following three problems: [0003] One is that the existing communication controllers only support one of the following communication methods, and cannot dynamically switch among these communication methods. One-to-one duplex communication mode, that is, communication occurs only between two terminals, is the communication mode of most communication controllers. The one-to-many simplex communication mode is a one-way communication mode in which one terminal sends the same data to multipl...

Problems solved by technology

[0006] The purpose of the present invention is to avoid the deficiencies of the prior art, and provide an asynchronous communication controller and its communication control method, so as to solve the problem that the existing communication controller and control method have a single communication corresponding mode and a single adaptation to the application environment. The problem of not being able to configure dynamically
