Abstract: A method and apparatus for transferring data between bus agents in a computer system. The present invention includes transmitting a control signal, from a first agent to a second agent, via a first transfer protocol; and, transmitting data corresponding to the control signal, from the first agent to the second agent, via a second transfer protocol. In one embodiment, the control signals are transmitted from the first agent to the second agent via a synchronous transmission with respect to a bus clock; and, the data is transmitted via an asynchronous transmission with respect to the bus clock, which has a data width greater than the synchronous transmission. In addition, in one embodiment of the present invention, the synchronous transmission is a common clock data transfer protocol, and the asynchronous transmission is a source clock data transfer protocol.

Abstract: A method and apparatus for transferring data between bus agents (102-105) in a computer system (100). The present invention includes transmitting a control signal (428, 426), from a first agent (102-105) to a second agent (102-105), via a first transfer protocol; and transmitting data (308) corresponding to the control signal (428, 426), from the first agent (102-105) to the second agent (102-105), via a second transfer protocol. In one embodiment, the control signals (428, 426) are transmitted from the first agent (102-105) to the second agent (102-105) via a synchronous transmission with respect to a bus clock (600); and, the data is transmitted via an asynchronous transmission with respect to the bus clock (600). The synchronous transmission is a common clock data transfer protocol, and the asynchronous transmission is a source clock data transfer protocol.
