ATM CELL TIMER DEVICE, CONTROLLING METHOD THEREOF AND BASE STATION/CONTROL STATION INTERFACE DEVICE HAVING ATM CELL TIMER DEVICE

摘要

PURPOSE: An ATM cell timer device is provided to confirm whether a counter reaches a threshold value, and to output information stored in a timer CAM(Content Addressable Memory) if the counter reaches the threshold value, thereby reducing a load of a CPU and securing QoS of ATM cells. CONSTITUTION: An input FIFO memory(300) inputs information on data stored in a memory without being outputted to AAL2 type ATM cells. A timer CAM(301) enables the inputted information to be stored or counted, depending on whether existing information exists. A timer counter(302) is operated according to settings of the timer CAM(301). An output FIFO memory(303) carries out an output interface function. A feedback FIFO memory(304) prevents the inputted information from being lost in consideration of a capacity of the CAM(301). A controller(305) controls each memory(300,301,303,304), and controls the inputted information.
