Abstract
A data transfer method and apparatus are provided for transferring data in a computer system on a high-speed synchronous multi-drop bus. Multiple devices including at least a first group of a plurality of devices and a second group of at least one device are connected to the high-speed synchronous multi-drop bus. To transfer data between devices in the first group, a first unidirectional data valid signal is applied to each device in the second group. The data from a sending device in the first group is transferred to a designated device in the second group. A second unidirectional data valid signal is applied to each device in the first group. The data is transferred from the designated device in the second group to a selected device in the first group.
