Abstract

The invention discloses a processor, a communication method, a storage medium and computing equipment. The processor comprises a plurality of processor cores, and each processor core is provided with a mailbox driver. The method comprises the steps that a source processor core calls an interface function in the mailbox driver to package a to-be-sent message, writes packaged message data into a specified register through a mailbox communication pipeline, and generates a message pointer corresponding to the specified register; the source processor core calls an interrupt generator in the mailbox driver to generate an interrupt request containing a message pointer and a target processor core identifier, and sends the interrupt request to the target processor core; and the target processor core processes the interrupt request and reads the message data from the specified register according to the message pointer contained in the interrupt request. The technical problem that in the prior art, the data transmission process between processor cores is tedious is solved.

Description

technical field [0001] The present application relates to the technical field of processors, and in particular, to a processor, a communication method, a storage medium, and a computing device. Background technique [0002] At present, ordinary chip inter-core communication needs to use interrupts for message notification, and then cooperate with the shared memory mechanism to transfer data information. This method is cumbersome and cannot be well supported for instant message transmission. This method has relatively large defects and deficiencies. : [0003] ①The driver code is complex and difficult to maintain [0004] The original communication method first needs to adapt the interrupt controller, and then use the function of each core's private interrupt controller to trigger the message, and then apply and use the memory. The combined use of the two major driver function components increases the difficulty of maintaining the driver code. For different boards, it is ne...
