Abstract

The invention discloses a microprocessor high-performance data communication method based on dual-ring buffer zone, including the steps: initializing a data receiving status structure and a data sending status structure; executing a data receiving routine and a data sending routine circularly by a query way; interrupting the data receiving routine or data sending routine which is executed at present through an interrupt service routine when receiving an interrupt signal generated from an interrupt source, and continuing to execute the circular detection process after execution of the interruptservice routine. The method has integral advantages of a microprocessor query communication method and an interrupt communication method, realizes high-performance receiving and sending of data between the microprocessor and other communication terminals, and particularly has the advantages of having good real-time performance, high reliability, high running speed, no blocking to other tasks andhigh routine execution efficiency, realizing relatively independent receiving and processing of messages and supporting processing to complicated communication tasks.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a microprocessor high-performance data communication method based on double ring buffers. Background technique [0002] With the rapid development of electronic technology, the application of microprocessor has penetrated into industry, agriculture, military, medical treatment, transportation and other industries, and it is the frontier field of global scientific and technological development. The microprocessor has the advantages of small size, low power consumption, simple structure, and stable operation, and is widely used in industrial monitoring and control occasions with high real-time requirements and relatively single functions; in recent years, the research on microprocessors has made great progress. It is specifically manifested in the improvement of the computing power of the microprocessor, the increase in the types and quantities of peripherals, the enhancement...
