Abstract

The invention discloses a multi-mode high-speed intelligent asynchronous serial port communication module and a realizing method thereof. A hardware architecture based by the multi-mode high-speed intelligent asynchronous serial port communication module is a CPCI (compact peripheral component interconnect) bus module. Hardware of the CPCI bus module comprises a programmable logic unit, a mass storage module, a general asynchronous receiving and transmitting controller, a high-speed digital isolator and an interface level switch device and the like. The invention has the advantages that: 1, an intelligent mode and a non-intelligent mode can be selected through software according to actual demands of a user; 2, when the multi-mode high-speed intelligent asynchronous serial port communication module is in the intelligent mode, data frame formats of all serial ports can be flexibly set through the software; and 3, when the multi-mode high-speed intelligent asynchronous serial port communication module is in the non-intelligent mode, the multi-mode high-speed intelligent asynchronous serial port communication module automatically judges data frame begins, data length, check, frame ends, and other information according to the set data frame formats during receiving the data.

Description

technical field [0001] The invention belongs to the technical field of communication interfaces, and specifically relates to a method for realizing multi-mode high-speed intelligent asynchronous serial port communication based on hardware logic. Background technique [0002] Serial communication has always played an important role in system control and data communication because of its simplicity, high reliability and easy programming. widely. [0003] However, due to the characteristics of serial port communication: the data exchange between the UART controller and the upper computer (CPU) is sent and received by byte, that is, the UART controller sends an interrupt signal to the CPU when it receives a message of 1 byte. Inform the CPU to fetch data, and the CPU will judge and process the correctness of the data (message head and tail identification, checksum, etc.), so the faster the serial port sends and receives data, the more interrupts it applies to the CPU per unit t...
