Problems solved by technology

[0002] The existing UART master control system needs the processor to observe the output state and configure the control register to switch the sending data source when switching the sending data source, which will not only consume a lot of processor resources but also greatly reduce the efficiency of sending data transmission. If If the sending module with multiple sending sources does not handle output monitoring and switching, it will cause the output data to be interleaved and confused

Abstract

The invention discloses a UART (Universal Asynchronous Receiver / Transmitter) master control system capable of automatically switching an outgoing data source in a multi-core scene. A plurality of sending cache control units are configured for a use scene needing a plurality of data sources; A hardware control module reads and identifies a plurality of continuous feature data written in a cache toautomatically switch to different sending data sources; Therefore, the operation efficiency is high, the data source can be accurately and automatically switched and sent, the data transmission efficiency can be improved when the method is applied to a UART system with a plurality of sending data sources, and the effect of saving the resource consumption of a processor is achieved.

Description

technical field [0001] The invention relates to the technical field of UART master control systems, in particular to a UART master control system that can automatically switch external data sources in a multi-core scenario. Background technique [0002] The existing UART master control system needs the processor to observe the output state and configure the control register to switch the sending data source when switching the sending data source, which will not only consume a lot of processor resources but also greatly reduce the efficiency of sending data transmission. If If the sending module with multiple sending sources does not handle the output monitoring and switching, it will cause the output data to be interleaved and confused. Contents of the invention [0003] The purpose of the present invention is to provide a UART master control system that can automatically switch the source of outgoing data in a multi-core scenario, so as to solve the problems raised in the...
