ABSTRACT:
One embodiment of a long-distance synchronous bus includes a sending unit and a receiving unit. The sending unit and receiving unit are configured to use credit-based handshaking signals to regulate data flow between themselves. The receiving unit includes a skid buffer for storing data packets received from the sending unit. The sending unit transmits one data packet to the receiving unit for each credit in possession and consumes one credit for each such transmitted data packet. The receiving unit transmits one credit to the sending unit for each data packet that is read out of the skid buffer. In another embodiment, transmitted data may be broadcast to multiple receiving units by routing the data from the sending unit to the multiple receiving units and maintaining separate credit-based handshaking signals for each receiving unit.
