Inventor: HONG HAN HEE
IPC: H04L12/28
Filed: 1998-07-30
Abstract: PURPOSE: An ATM(Asynchronous transfer mode) cell dividing device is provided to support broadcast and multicast functions. CONSTITUTION: According to control data transmitted from a host controller, a control register(121), N-1 numbers of port registers(122-125) and a broadcast register(126) are set.

A delay part(160) delays the ATM cell by a predetermined clock according to the control signal. A comparative part(130) compares a header of the ATM cell with a setting value of the port register or a setting value of the broadcast register, and outputs the result thereof. N numbers of FIFOs(170a-170e) sequentially store the ATM cells transmitted from the delay part and sequentially output them. A controller(140) transfers the control signal for selecting the register value to the comparative part and the delay part, and also transfers the control signal to the FIFO of the port which is selected by receiving the comparison result from the comparative part so as to store the received ATM cell. Accordingly, broadcast and multicast functions can be easily performed, thereby simplifying the device configuration for processing the received cell and providing various functions additionally.
