摘要： Multiple initialization techniques for system and component in a point-to-point architecture are discussed. Consequently, the techniques allow for flexible system/socket layer parameters to be tailored to the needs of the platform, such as, desktop, mobile, small server, large server, etc., as well as the component types such as IA32/IPF processors, memory controllers, IO Hubs, etc. Furthermore, the techniques facilitate powering up with the correct set of POC values, hence, it avoids multiple warm resets and improves boot time. In one embodiment, registers to hold new values, such as, Configuration Values Driven during Reset (CVDR), and Configuration Values Captured during Reset (CVCR) may be eliminated.For example, the POC values could be from the following: Platform Input Clock to Core Clock Ratio, Enable/disable LT, Configurable Restart, Burn In Initialization Mode, Disable Hyper Threading, System BSP Socket Indication, and Platform Topology Index.
摘要翻译：讨论了用于系统和组件在点对点架构中的多个初始化技术。因此，这些技术允许根据平台（如桌面，移动，小型服务器，大型服务器等）的需求以及诸如IA32 / IPF处理器之类的组件类型来定制灵活的系统/套接字层参数，存储器控制器，IO集线器等。此外，该技术有助于以正确的一组POC值加电，因此避免了多次热复位并提高了启动时间。在一个实施例中，可以消除保存新值的寄存器，例如在复位期间驱动的配置值（CVDR）和在复位期间捕获的配置值（CVCR）。例如，POC值可以来自以下内容：平台输入时钟到核心时钟比率，启用/禁用LT，可配置重新启动，刻录初始化模式，禁用超线程，系统BSP插槽指示和平台拓扑索引。

摘要： Various methods and apparatus are described for communicating transactions between one or more initiator IP cores and one or more target IP cores coupled to an interconnect. Tag logic may be located within the interconnect, such as located in an agent, and configured to assign different interconnect tag identification numbers to two or more transactions from a same thread. The tag logic assigns different interconnect tag identification numbers to allow the two or more transactions from the same thread to be outstanding over the interconnect to two or more different target IP cores at the same time, allow the two or more transactions from the same thread to be processed in parallel over the interconnect, and potentially serviced out of issue order while being returned back to the multiple threaded initiator IP core realigned in expected execution order.

摘要： An interconnect-power-manager (IPM) cooperates and communicates signals with an integrated-circuit-system-power-manager (SPM) in the integrated-circuit. The interconnect network (IN) is partitioned into multiple power domains and has hardware circuitry integrated into the IN to manage a quiescent state for all components in each power domain in the IN when a routing pathway for transactions in the IN spans across one or more power domain boundaries and causes interdependencies of power domains within the IN other than where the power domains of the initiator agent and final target agent of the transaction are located within. The SPM is configured to cooperate and communicate with the IPM to quiesce, to wake up, and any combination of the two, one or more of the multiple power domains within the IN.

摘要： A method includes receiving flits forwarded from an upstream router into a first input virtual channel (VC) associated with an input port. The flits are associated with packets originated from a first Intellectual Property (IP) core and forwarded to a second IP core. The flits are stored in a VC storage associated with the first input VC. The method further includes performing link width conversion based on a width of the flits being different from a width of an output port. Link width conversion includes accumulation of the flits when the width of the output port is wider and unpacking of the flits when the width of the output port is narrower. Credits are generated based on the flits being forwarded from the first input VC to the output port. The credits are sent to the upstream router to enable receiving more flits from the upstream router.

摘要： A method for generating headers in packetized protocols for a flexible routing network for a Network on a Chip (NoC) architecture includes generating packets based on transmission traffic received from an initiator or a target connected to a routing network that connects disparate initiators and targets. Logic to generate the packets is in an interface located between the initiator or the target and the routing network. A header portion of a packet is variable in length and includes a header payload and header control information. Each of the header portion and the body portion includes one or more standard sized transmission units. The size of the transmission units and width of the header payload are determined by logic included in the interface. The width of the header payload is determined based on orthogonal groups with each of the orthogonal groups being associated with targets sharing an initiator thread.

摘要： A method for routing information in a flexible routing network which connects disparate initiators and targets includes implementing a packetization logic at an interface between an initiator or a target and a routing network to receive transmission traffic from the initiator or the target and to packetize the transmission traffic into packets. Each packet includes header and body portions. Each of the header and body portions includes one or more standard sized transmission units. Each standard sized transmission unit includes control and payload sections. A payload section associated with the body portion includes one or more chunks. The method includes encoding the one or more chunks using a Common Data Format (CDF). All transmissions within the routing network are based on the CDF. The CDF facilitates narrow-to-wide and wide-to-narrow link width conversion without having to manipulate subparts of data fields in the transmission traffic.
