Abstract

The invention discloses a dual-core communication method and electronic equipment. The method comprises the following steps: sending a to-be-transmitted data packet in a first private memory of a first processor to a shared memory according to a preset polling cycle, so that the shared memory fills the to-be-transmitted data into a first annular data structure; sending an interrupt instruction to a second processor; and if the second processor receives the to-be-transmitted data in the shared memory in response to the interrupt instruction, starting a receiving interrupt task to wait for the to-be-transmitted data sent by the second processor. By means of the technical scheme, the utilization rate of the two processors can be effectively increased, the real-time requirement for data communication in the case of small data volume is met, the problem that the occupancy rate of a data receiving CPU is high in the case of large data volume is solved, and the efficiency of data interaction between dual-core CPUs is improved.

Description

Technical field [0001] Embodiment of the invention relates to the field of embedded systems, particularly to a dual-core communication method and an electronic apparatus. Background technique [0002] In embedded systems, embedded processor without a doubt is the core devices. Different CPU core has a different structure which have different characteristics, dual-core embedded processors often the data is received after a CPU in an internal space subjected to processing other CPU is required to copy data into their processed the next step of the process's private memory for the processing of time-sensitive data. Therefore, the rate and other information and data exchange between different CPU core is an important factor affecting the performance of embedded systems. [0003] Currently communication between the multi-core embedded processor core to use more shared memory mode, i.e., open up a memory space in the physical memory space, the CPU core or different received through the...
