ABSTRACT:
A method and apparatus for transferring data between bus agents in a computer system including a bus operating at a bus clock rate. The method includes the step of receiving a transaction request from a requesting agent including an indication of a plurality of data widths the requesting agent processes. In response to the transaction request, a data transmission is configured in accordance with a data width that both the requesting agent and a responding agent process. The data transmission is performed asynchronously with respect to the bus clock if the data width is one of a first plurality of data widths, otherwise, the data transmission is performed synchronously with respect to the bus clock.
