[0058] refer to image 3 , image 3 It is a schematic flowchart of the second embodiment of the dual-processor communication method of the present invention. Based on the above-mentioned first embodiment, step S20 includes:

[0059] Step S21, obtaining the associated data after the first processor processes the target data;

[0060] After the first processor reads the target data, it will process the target data. Specifically, how to process the target data can be a reply to the request, an analysis and summary of scattered data, or an analysis of the data. The analysis performed is not limited here. The first processor processes the target data to obtain associated data, wherein the associated data may be result data after processing the target data, or may be data after analyzing the target data.

[0061] There is a certain logical relationship between the target data and the associated data, similarly, the target data is equivalent to the flour pulled by the second proce...

Abstract

The invention discloses electronic equipment. The electronic equipment comprises: a first processor; a second processor, wherein the first processor is connected with the second processor through a signal line; and an internal memory which comprises an input/output port, wherein the first processor and the second processor are connected with the input/output port through a connection bus. The invention further discloses a communication method of the dual processors. According to the invention, a simple line connection relationship and a single-port RAM with low price are adopted to achieve communication between the two processors; and after the interrupt signal of the other processor is received, the processor is communicated with the path between the processor and the internal memory, reads the target data and writes the associated data, so that the communication conflict caused by the simultaneous access of the two processors to the internal memory can be effectively avoided, and theproduction cost of the electronic equipment is reduced.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to an electronic device and a communication method for dual processors. Background technique [0002] In the field of industrial control, if a single CPU is difficult to meet the high-speed real-time communication requirements of large-scale industrial equipment, the functions are usually decomposed on two CPUs. However, since the two CPUs access the memory at the same time, there will be communication conflicts, resulting in equipment failure. [0003] The above content is only used to assist in understanding the technical solution of the present invention, and does not mean that the above content is admitted as prior art. Contents of the invention [0004] The main purpose of the embodiments of the present invention is to provide an electronic device, aiming to solve the technical problem in the prior art that two CPUs access the memory at the same time, there will be communic...
