Bridge between two buses of a computer system that latches signals from the bus for use on the bridge and responds according to the bus protocols

A computer system comprising:

• a first bus;
• a second bus carrying control signals and having a specified bus protocol;
• at least one master coupled to the second bus;
• a bridge coupled between the first and second buses for interfacing the first and second buses, the bridge including:
• a third bus carrying latched control signals received from the second bus;
• at least one slave coupled to the third bus and receiving latched control signals from the third bus;
• a latch coupled between the second and third buses and latching control signals sent from the second bus to the third bus, and latching control signals sent from the third bus to the second bus;
• a logic device coupled between the second and third buses, the logic device sending, in response to receiving predetermined unlatched master control signals from the master coupled to the second bus, predetermined unlatched slave control signals to the master on the second bus, wherein the predetermined unlatched master control signals are for a predetermined type of data transfer between the master coupled to the second bus and the slave coupled to the third bus.
