Heterogeneous multi-core asynchronous communication method and device

Abstract

The invention discloses a heterogeneous multi-core asynchronous communication method and device, and the method comprises the steps: automatically storing to-be-transmitted data in a shared information pool of a data transfer end, and transmitting an interrupt signal to at least one communication end which needs the data through the data transfer end, so that the at least one communication end needing the data automatically reads the required data in the shared information pool after receiving the interrupt signal, heterogeneous multi-core communication can be realized, and the identificationinformation corresponding to the at least one communication end needing the data is stored in the shared information pool together; therefore, at least one communication end needing the data can readthe required data according to the identification information, efficient cooperative communication among heterogeneous multi-cores can be achieved, the resource utilization rate of the shared messagepool can be increased, the number of the communication ends can be increased according to requirements under the condition that hardware cost is not increased, and thus communication among more heterogeneous multi-cores can be realized.

Description

technical field

[0001] The present invention relates to the field of communication technology, in particular to a heterogeneous multi-core asynchronous communication method and device. Background technique

[0002] With the rapid development of intelligent Internet of Things technology, the "pipe" in the ecological structure of "cloud pipe end" will be directly enhanced, the transmission delay of data will be reduced, and the throughput will be increased. Another change is that the end-side (application The algorithm of terminal (abbreviation) is continuously enriched and optimized, the complex algorithm is constantly moving forward, and the corresponding hardware-level computing power is also moving to the device side. To meet the computing power requirements of different applications, the SoC (system on chip) architecture must be Consider efficient synergy among heterogeneous multi-cores.
