Abstract: A transmission/reception concurrent matching apparatus for a multiple of TDM channels and a method thereof, wherein in matching the TDM channels, upon data transmission, a signal Serial Communication Controller(SCC) stores data to transmit per each data channel into a multiple of First-in First-out buffers(FIFOs) and transmits in order the data from each FIFO by one byte through a TDM bus, and upon data reception, stores the received data through the TDM bus into each FIFO and processes the data from each FIFO by reading out the data in order. As the number of SCC is reduced, the cost to process the data is saved.

Abstract: An apparatus and method for interrupt processing are provided, in which an interrupt is latched in a synchronous system in order to process the interrupt of a code division multiple access switching apparatus. An interrupt of higher priority order is processed by arbitrarily designating the priority order of the interrupt, and then an interrupt of lower priority order is processed in order, regardless of the priority order, thereby being used in a control system of the code division multiple access switching apparatus to which an interrupt having no priority order is applied.

Abstract: An improved destination address detection apparatus for a hardware packet router capable of detecting the address of the destination to which the packet data is transmitted, not using the central processing unit, which includes a serial/parallel converter for converting a serial packet data inputted thereto into a parallel packet data; a buffer for storing the parallel packet data outputted from the serial/parallel converter therein and for outputting in a first-in-first-out method; an address detector for detecting an address of a destination, to which the address is transmitted, from the parallel packet data outputted from the buffer; and an "n" number of buffers, which are activated in accordance with an address of the destination detected by the address detector, for storing the packet data and for outputting in a first-in-first-out method, wherein said address detector includes an "n" number of latches, which are connected in series, for sequentially shifting the output signals of the buffer and for stor
