发明名称 Multiprocessing system and method for assembly of asynchronous transfer mode cells
摘要 <p>An assembly/disassembly system is comprised of a cell assembly and a cell disassembly, each assembly having one buffer memory (12, 910) with its memory area logically divided into a plurality of data areas (banks). The cell assembly receives TDM data to assemble ATM cells by storing the TDM data into the respective banks according to the virtual channels. When one of said banks stores the TDM data in the payload length of an ATM cell, an new bank (unused bank) is specified to store the TDM data successively. An ATM cell is formed by using the data read out from the bank where the TDM data is stored in the payload length of an ATM cell. The cell disassembly receives ATM cells from the ATM highway (5) to disassemble the ATM cells into TDM data by using the buffer memory. The payload of a received cell is stored into an unused bank of the buffer memory. A chain of the bank addresses each storing the payload of the received ATM cell is formed for each virtual channel of received ATM cells. According to a bank address read out from the chain corresponding to each channel of the TDM highway (11), the data as the TDM data is read out from the buffer memory. <IMAGE></p>
