Abstract: The Multicore Bus Architecture (MBA) protocol includes a novel technique of sharing the same physical channel for all transaction types. Two channels, the Transaction Attribute Channel (TAC) and the Transaction Data Channel (TDC) are used. The attribute channel transmits bus transaction attribute information optionally including a transaction type signal, a transaction ID, a valid signal, a bus agent ID signal, an address signal, a transaction size signal, a credit spend signal and a credit return signal. The data channel connected a data subset of the signal lines of the bus separate from the attribute subset of signal lines the bus. The data channel optionally transmits a data valid signal, a transaction ID signal, a bus agent ID signal and a last data signal to mark the last data of a current bus transaction.
