Abstract:
The method includes the following steps: monitoring an actual value of a relevant parameter of a display bandwidth of data to be output by the memory; comparing the actual value of the relevant parameter with a threshold to determine whether the actual display bandwidth meets predetermined requirements; and selecting an access arbitration mode for the memory according to whether the predetermined requirements are met. The access controller includes: a monitoring and comparing unit, adapted to monitor an actual value of a relevant parameter of a display bandwidth of data to be output by the memory and compare the actual value of the relevant parameter with a threshold to determine whether the actual display bandwidth meets predetermined requirements; and an arbitration adjusting unit, adapted to select an access arbitration mode for the memory according to whether the predetermined requirements are met.
