Abstract
A method and apparatus for post-driving and pre-driving a terminated bus that shortens dead cycles on a bus during bus master change-overs. In one embodiment, a first bus agent giving up control of the bus drives the bus to termination voltage levels during a first portion of the dead cycle. A second bus agent gaining control of the bus also drives the bus to termination voltage levels during a last portion of the dead cycle. For the time period between the first portion and the second portion, termination components such as resistors or transistors maintain the bus at termination voltage levels. By driving the bus to termination voltage levels with bus agents, bus transients are settled more quickly than with termination components alone, which improves performance of the bus over configurations pulled to termination voltage levels with termination components alone.
