摘要： Systems and methods for relate to bus ring performance monitoring and control. A bus ring includes an agent and a switch unit to connect the agent to the bus ring. The switch unit includes a transmit queue to store data from the bus ring to be transmitted to the agent and a receive queue to store data from the agent to be transmitted to the bus ring. A first counter is implemented to track a number of pending transactions in the transmit queue and a second counter is implemented to track a number of times the receive queue is full and unable to accept additional data. Frequency of the bus ring is increased or decreased based on comparison of values of the first counter and the second counter with corresponding predefined high and low threshold values.
