    • A spread spectrum clock generator comprises a conventional closed-loop VCO and an open-loop VCO where both are coupled to the same point of the PLL. Both VCOs comprise a V-to-I converter followed by a current-controlled oscillator and are identical in design but only the open-loop VCO receives the modulation current to generate the spread spectrum clock signal. The open-loop ICO is part of the spread spectrum generator and in one embodiment of the invention receives feedback current signals representing the modulation method and modulation ratio. This ensures that the modulated clock output tracks the PLL output frequency. In a second embodiment the closed-loop VCO receives from the spread spectrum generator the feedback current signal representing the modulation method (center/down spread) while the open-loop VCO receives the feedback signal representing the modulation ratio.
    • 扩频时钟发生器包括常规闭环VCO和开环VCO,其中两者都耦合到PLL的相同点。 两个VCO都包括一个V-to-I转换器,随后是一个电流控制的振荡器,并且在设计上是相同的,但只有开环VCO接收调制电流以产生扩频时钟信号。 开环ICO是扩频发生器的一部分,并且在本发明的一个实施例中,接收表示调制方法和调制比的反馈电流信号。 这样可以确保调制时钟输出跟踪PLL输出频率。 在第二实施例中,闭环VCO从扩展频谱发生器接收表示调制方法的反馈电流信号(中心/向下扩展),而开环VCO接收到表示调制比的反馈信号。

    • A method of providing coherent shared memory access among a plurality of shared memory multiprocessor nodes. For each line of data in each of the nodes, a list of those processors of the node that have copies of the line in their caches is maintained. If a memory command is issued from a processor of one node, and if the command is directed to a line of memory of another node, then the memory command is sent directly to an adapter of the one node. When the adapter receives the command, it forwards the command from the one adapter to another adapter of the other node. When the other adapter receives the command, the command is forwarded to the local memory of the other node. The list of processors is then updated in the local memory of the other node to include or exclude the other adapter depending on the command. If the memory command is issued from one of the processors of one of the nodes, and if the command is directed to a line of memory of the one node, then the command is sent directly to local memory. When the local memory receives the command and if the adapter of the node is in the list of processors for a line associated with the command and if the command is a write command, then the command is forwarded to the adapter of the one node. When the adapter receives the command, the command is forwarded to remote adapters in each of the remote nodes which have processors which have cache copies of the line. Finally, when the latter remote adapters receive the command, the command is forwarded to the processors having the cache copies of the line.
    • 一种在多个共享存储器多处理器节点之间提供一致的共享存储器访问的方法。 对于每个节点中的每一行数据,维护节点中具有其高速缓存中的行的副本的那些处理器的列表。 如果从一个节点的处理器发出存储器命令,并且如果命令被定向到另一个节点的存储器行,则存储器命令被直接发送到该一个节点的适配器。 当适配器接收到命令时,它将该命令从一个适配器转发到另一个节点的另一个适配器。 当另一个适配器接收到该命令时,该命令将转发到另一个节点的本地内存。 然后在另一个节点的本地存储器中更新处理器列表,以根据命令包括或排除另一个适配器。 如果从其中一个节点的一个处理器发出存储器命令,并且如果命令被定向到一个节点的存储器行,则该命令被直接发送到本地存储器。 当本地内存接收到该命令时,如果节点的适配器位于与该命令相关联的一行的处理器列表中,并且该命令是写入命令,则该命令将转发到该一个节点的适配器。 当适配器接收到该命令时,该命令将转发到具有具有该行的高速缓存副本的处理器的每个远程节点中的远程适配器。 最后,当后一个远程适配器接收到该命令时,该命令被转发到具有该行的缓存副本的处理器。
