    Abstract: An example embodiment of a computer system that includes a removable agent that can be removed or installed without powering down the system includes a fixed bus agent and the replaceable bus agent. The fixed bus agent and the replaceable bus agent are electrically coupled together by a presence detect signal, a synchronization signal, and a data bus. A deassertion of the presence detect signal indicates to the fixed bus agent that the removable bus agent has been disconnected and is no longer electrically coupled to the fixed bus agent. The fixed bus agent then tri-states its outputs and also prevents potentially invalid data from being delivered to the core circuitry of the fixed bus agent. An assertion of the presence detect signal indicates to the fixed bus agent that the replaceable bus agent is electrically connected to the fixed bus agent. In response to the assertion of the presence detect signal, the fixed bus agent and the replaceable bus agent enter reset periods. Following the reset periods and when each bus agent is ready to communicate to the other agent, the fixed bus agent and the replaceable bus agent signal to each other over the synchronization signal that each is ready to begin communication over the data bus.

    Abstract translation: 包括可以在不关闭系统的情况下被移除或安装的可移除代理的计算机系统的示例性实施例包括固定总线代理和可更换总线代理。 固定总线代理和可更换总线代理通过存在检测信号,同步信号和数据总线电耦合在一起。 存在检测信号的取消表示向固定总线代理指示可移除总线代理已经断开并且不再电耦合到固定总线代理。 固定总线代理将其输出三态化,并且还防止潜在的无效数据被传送到固定总线代理的核心电路。 存在检测信号的断言向固定总线代理指示可更换总线代理电连接到固定总线代理。 响应于存在检测信号的确认,固定总线代理和可更换总线代理进入复位周期。 在复位周期之后,当每个总线代理准备好与其他代理通信时,固定总线代理和可更换总线代理器通过同步信号相互信号,每个同步信号准备好通过数据总线开始通信。

    Abstract: An integrated circuit 301 has an internal transmission line 315 which receives a signal from an external transmission line 305. No termination circuitry is used to terminate the external transmission line. The internal transmission line transmits the signal passively to two or more different circuits 331, 332 on the integrated circuit. The internal transmission line may be terminated 318 at the opposite end to the external transmission line. The impedance of the internal transmission line may be matched to that of the external line. The internal transmission line may be connected to the circuits using buffers. Two transmission lines may be used to transmit differential signals.

    Abstract: For one disclosed embodiment, an integrated circuit may comprise an internal transmission line in one or more layers of the integrated circuit. The internal transmission line may be coupled to receive a signal from an external transmission line at a first end of the internal transmission line without use of termination circuitry. The internal transmission line may transmit the signal passively to a second end of the internal transmission line. The integrated circuit may also comprise first circuitry having an input coupled to the internal transmission line at a first location of the internal transmission line to receive the signal and second circuitry having an input coupled to the internal transmission line at a second location of the internal transmission line to receive the signal. The second location may be different from the first location. Other embodiments are also disclosed.
