Abstract:
In a computer system having a plurality of busses coupled by a bridge, a system for implementing pseudo delayed transactions between devices coupled to busses on either side of the bridge, comprising:a first initiator coupled to a first bus, said first initiator adapted to request ownership of said first bus and receive a first grant signal from an arbiter responsive thereto;a second initiator coupled to said first bus, said second initiator adapted to request ownership of said first bus and receive a second grant signal from said arbiter responsive thereto;a target device coupled to a second bus; anda bridge coupled to said first bus and said second bus for implementing data transactions between said target device and said first initiator or said second initiator, said bridge adapted to store said second grant signal to support a pseudo delayed transaction by said second initiator when said bridge is busy executing a current transaction from said first initiator to said target device such that said second device is guaranteed access to said target device, wherein said bridge stores said second grant signal and does not store address or command/byte enable signals from said second initiator to support said pseudo delayed transaction.
