Abstract
A bridge for communicating between a first and a second bus includes a first interface unit, a second interface unit and a buffer unit. The first interface unit is adapted to be coupled to the first bus. The second interface unit is adapted to be coupled to the second bus. The buffer unit is coupled to the first and second interface units. The buffer unit is adapted to receive a posted transaction from one of the first and second interface units. The buffer unit includes a posting buffer and a discard timer. The posting buffer is adapted to store the posted transaction. The discard timer is adapted to generate a discard timer expired signal after a predetermined time interval that the posted transaction has resided in the posting buffer. A method for exiting from a potential deadlock situation includes posting a transaction, tracking the length of time the transaction has been posted, and discarding the transaction after a predetermined time interval that the transaction has been posted.
