ABSTRACT:
An ATM cell forming device includes a memory, an SAR processing device, and a switch. The memory stores output channel information, cell header information, and frame information to be formed into cells. The SAR processing device assembles frame information into ATM cells by referring to the memory. The switch distributes the cells to the respective output channels. The SAR processing device includes an input frame distributing section, cell header read sections, and a cell assembly section. The input frame distributing section identifies output channels for pieces of frame information by referring to the memory on the basis of pieces of correspondence information, and distributes the pieces of frame information to the respective identified output channels. The cell header read sections are arranged in correspondence with outputs of the input frame distributing section for the respective output channels to read out pieces of cell header information for the respective output channels from the memory and store these pieces of information. The cell assembly section selects one of the cell header read sections, reads out cell header information from the selected section and frame information from the memory, assembles the pieces of information into ATM cells, and outputs them to the switch.
