<p>A method of accessing data from a plurality of DSUs allows for data to be accessed over a bi-directional data bus at full bus speed. If the execution of a bus cycle requires switching bus drivers that drive the data bus, a dummy cycle is executed before valid data may be presented on the bus. The execution of dummy cycle ahead of presenting data on the data bus allows for the elapse of a bus settlement time associated with physical properties of the data bus, thereby making it possible to operate the data bus at full speed.</p> |
