Abstract:
1. A device for switching data from a first bus to a second bus in a switching system, comprising circuitry operable to: access a code for each of a plurality of first time slots, each code operable to combine with corresponding data received from the first bus to specify one of a plurality of previously stored operations; apply the specified operation for each first time slot to the data for each first time slot to generate modified data for each first time slot; access information specifying one of a plurality of second time slots associated with the second bus to correspond to each first time slot, the information for each second time slot representing an address; and store the modified data for each first time slot of a previous frame, store the modified data for each first time slot of a current frame, locate the modified data for each first time slot of the previous frame according to the address, and communicate the modified data for each first time slot of the previous frame to the second bus in the corresponding second time slot while the modified data for the current frame is being stored.
