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.
