Abstract
An electronic apparatus includes a memory, first and second bus masters, a counting unit and a control unit. The first and second bus masters are capable of accessing the memory. The counting unit counts an amount of addresses reserved by the second bus master for accessing the memory. The control unit controls to avoid permitting a request made by the second bus master if a value counted by the counting unit becomes larger than a first threshold value, until the value counted by the counting unit becomes smaller than a second threshold value. The request made by the second bus master is used to reserve addresses of the memory, and the second threshold value is smaller than the first threshold value.
