Abstract
In one embodiment, in a switching system, an ASIC device on a card coupled to a backplane communicates switched data to an outgoing network interface for the card without using the backplane, and remaining ASIC devices on the card communicate switched data, to other cards using the backplane for communication to outgoing network interfaces for the other cards. In another embodiment, an ASIC device includes a RAM storing a code for each first slot to combine with corresponding data from a first bus to specify an operation, a RAM applying the operation to generate modified data for each first slot, a RAM communicating as an address information specifying a second slot to correspond to each first slot, and a RAM locating the modified data for each first slot of a previous frame according to the address and communicating this modified data to a second bus in the corresponding second slot while the modified data for a current frame is being stored.
