Abstract

The present invention provides a multi-master system interactive communication and management method and device. The method includes the following steps: in response to a user sending an instruction to the master system, the master system writes to its corresponding control right register on a programmable logic device A control right indicator, and synchronizing the control right indicator to other main systems; the programmable logic device periodically polls all the control right registers, and responds to the existence of the control right indicator in a plurality of control right registers , and according to the preset priority, the control instruction of the main system with the highest priority is transmitted to the peripheral equipment for control; and the control instruction of the main system with the highest priority is synchronized to other main systems. The invention realizes the interactive communication and management of the multi-master system, ensures the barrier-free data communication and avoids the conflict.

Description

technical field [0001] The present invention relates to the computer field, and more specifically, relates to a multi-master system interactive communication and management method and device. Background technique [0002] In systems such as switches, the CPLD-FPGA chip controls the power-on and power-off sequence control, communication control, button detection, fan speed control, SFP lighting control and serial port switching, I2C multi-master control, high-speed data interaction, etc. of the entire switch. CPLD-FPGA controls the working state of some key devices, so it is closely related to the working state of the entire hardware of the switch system. At the same time, CPLD-FPGA is a semi-custom application-specific integrated circuit, which has a series of advantages such as flexible programming, fast response, and high integration. It has been more and more widely used in the field of early development verification and control applications. [0003] Upstream controller...
