Method and system for processing data conflict

A system for processing a data conflict, comprising:

• a plurality of master devices;
• a slave device;
• and
• a power management bus (PMBus) coupled to the master devices and the slave device, wherein the each master device accesses the slave device over the PMBus to perform power management, wherein the PMBus arbitrates amongst the master devices to allow only one of the master devices sending a PMBus command to the slave device at a time,
• wherein the each master device comprises an adaptive voltage scaling (AVS) module, wherein the AVS module comprises:
• a command sending unit configured to send a PMBus command to the slave device by using the PMBus;
• a determining unit configured to detect that the PMBus command has failed to be sent and in response to the detection, including determining that an ownership of the PMBus has been granted by the PMBus to a second master device of the plurality of master devices at a point in time, determine whether a number of times that the PMBus command fails to be sent is greater than or equal to a preset value when the PMBus command fails to be sent, wherein the preset value is configured in advance during system initialization;
• and
• a timing unit configured to start timing when the number of times that the PMBus command fails to be sent is less than the preset value, and wherein the command sending unit is further configured to resend the PMBus command when timing duration of the timing unit reaches resending time, wherein the resending time is specifically associated with the first master device, wherein the resending time is greater than time required for sending a shortest PMBus command by any of the master devices, and wherein the resending time is less than or equal to a sum of time required for sending a longest PMBus command by all of the master devices in a system.
