ABSTRACT:
A microprocessor interface system including a system bus with a bus clock and a data signal group in which multiple devices are coupled to the system bus. Each device is configured to perform a half-width data transaction on the system bus in which a doubleword is transferred for each of four beats during each of four consecutive cycles of the bus clock. The data signal group may include multiple data strobes, such as first and second data strobes for latching first and third doublewords and third and fourth data strobes for latching second and fourth doublewords during each cycle of the bus clock. Each doubleword may be provided on first and second data portions of the data signal group. The first and second data strobes may latch data on the first data portion and the third and fourth data strobes may latch data on the second data portion.
