Problems solved by technology

[0008] In the prior art, two different methods are used to solve the message transfer between processors. No matter which method is adopted, the sending processor only sends one message at a time, and the receiving processor only receives one message at a time, so the efficiency of message transfer is relatively high. Low

Embodiment Construction

[0069] The method of the invention can realize the continuous sending and receiving of message transfer between processors without any interruption and overhead, and can respond in real time by sending interruption information to messages that need to be processed urgently. The present invention will be described in detail below in conjunction with the accompanying drawings.

[0070] see figure 2 , the method of the present invention comprises:

[0071] Step S201: the sending processor writes the determined storage address of the next message and the message sent this time into the memory;

[0072] Step S202: the sending processor records the determined storage address of the next message in the write address unit;

[0073] Step S203: after the receiving processor inquires that there is a new message in the memory, it obtains the message and the storage address of the next message from the storage address recorded in the read address unit;

[0074] Step S204: the receiving...

Abstract

The invention discloses method and device for transferring messages between processors. The method includes steps: transmission processor writes address of memory of next piece of message determined, and message to be sent this time in memory; the transmission processor records address of memory of next piece of message in write address unit; after having queried that there is new message in the said memory, the reception processor obtains the said message and the address of memory of next piece of message from address of memory recorded in read address unit; the reception processor writes the address of memory of next piece of message to the read address unit. The invention also discloses a sort of transmission processor and a sort of reception processor.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a method and device for transmitting messages between processors. Background technique [0002] Messages between processors in large systems are usually connected through dual-port memory, and messages between processors are passed through interrupts or flag bit queries. [0003] No matter which way of work is adopted, there is no big difference in the process of its work. see figure 1 , figure 1 It includes two processors, a sending processor 101 and a receiving processor 102, and a dual-port memory 103 is connected to the two processors. [0004] If the message is transmitted in an interrupt mode, when the sending processor 101 needs to send a message, it first judges whether there is enough space in the dual-port memory 103 to store the currently sent message. If there is enough space in the dual-port memory 103, the sending processor 101 writes the message to th...
