Method and device for implementing end-to-end hardware message transmission

Abstract

The invention discloses a method and device for realizing end-to-end hardware message transmission. The device includes: a message memory, a controller, and a message input and output interface. The message storage is used to temporarily store the message; the controller is used to perform the hardware management of the message, store the message obtained from the message input interface in the message storage, read the message from the message storage and send it through the message output interface For message consumers; message input interface, directly connected to the message creator, used to obtain the message created by the message creator under the control of the controller; message output interface, directly connected to the message consumer, used to obtain the message created by the message creator under the control of the controller , to provide the message to the message consumer. Through the invention, the efficiency of message transmission can be improved, and the overhead of software management can be reduced.

Description

technical field [0001] The present invention relates to the technical field of message passing (message passing), in particular to a method and device for realizing end-to-end hardware message passing (HMP, Hardware Message Passing). Background technique [0002] With the development of technology, the system becomes more and more complex, and the number of integrated cores (core) is also increasing, and the communication between cores is becoming more and more important. Traditional inter-core communication is usually realized by hardware of shared memory, such as figure 1 As shown, multiple cores are connected to a shared memory through an interconnection system. The advantage of this implementation is that cross information transfer between multiple cores can be achieved, while the disadvantages include: [0003] 1. The message transmission delay is relatively long. This is because the message transmission needs to be written to the shared memory by the message creator ...

AI Technical Summary

Problems solved by technology

This implementation method of message transmission using a direct connection interface has the following defects: first, the processor must be scalable, and can be extended to message sending or message receiving ports; second, this method still requires software for message management, and there is no Reduce the overhead of software management, just reduce the delay of message transmission
