    • A method of interfacing two components of a computing system is provided wherein the method includes providing a pair of unidirectional, point-to-point buses to transmit data between a master bus controller of the computing system and a slave bus controller of a processor unit of the computing system. The method also includes providing means for transmitting a command packet with an address associated with data pertaining to the command from the master bus controller to the slave bus controller. In addition, the method includes providing means for determining by the slave bus controller whether the slave bus controller can accept the command. The method further includes providing means for transmitting an acknowledgement from the slave bus controller to the master bus controller after the slave bus controller receives a first signaling interval for the command packet if the slave bus controller can accept the command packet.
    • 提供了一种接口计算系统的两个组件的方法,其中所述方法包括提供一对单向点对点总线以在所述计算系统的主总线控制器与所述计算系统的总线控制器之间传送数据, 计算系统。 该方法还包括提供用于发送具有与从主总线控制器到从总线控制器的命令有关的数据相关联的地址的命令分组的装置。 此外,该方法包括提供用于由从总线控制器确定从总线控制器是否可以接受命令的装置。 该方法还包括提供用于在从总线控制器接收到命令分组之后从属总线控制器接收到用于命令分组的第一信令间隔的从总线控制器向主总线控制器发送确认的装置。
