Abstract:
A receive block for asynchronous transfer mode (ATM) cell delineation, comprising:a plurality of cell delineation blocks each coupled to receive an associated serial bit stream, each cell delineation block operating to identify ATM cell boundaries in the serial bit stream and convert ATM cell payloads to parallel data words;a memory having a plurality of memory blocks organized having a memory block associated with each cell delineation block, each memory block having a plurality of ATM cell storage locations;a memory controller coupled to the cell delineation blocks and the memory, the memory controller operating to read data words from the cell delineation blocks and write data words to one of the cell storage locations in associated memory blocks; anda bus controller coupled to the memory controller and to the memory, the bus controller operating to interface with an ATM physical layer, to receive a memory status signal from the memory controller and to provide signals to the memory for communicating an ATM cell across the ATM physical layer.
