摘要： Systems and methods for distributing thread instructions in the pipeline of a multi-threading digital processor are disclosed. More particularly, hardware and software are disclosed for successively selecting threads in an ordered sequence for execution in the processor pipeline. If a thread to be selected cannot execute, then a complementary thread is selected for execution.

摘要： Systems and methods for implementing multi-frame control blocks in a network processor are disclosed. Embodiments include systems and methods to reduce long latency memory access to less expensive memory such as DRAM. As a network processor in a network receives packets of data, the network processor forms a frame control block for each packet. The frame control block contains a pointer to a memory location where the packet data is stored, and is thereby associated with the packet. The network processor associates a plurality of frame control blocks together in a table control block that is stored in a control store. Each table control block comprises a pointer to a memory location of a next table control block in a chain of table control blocks. Because frame control blocks are stored and accessed in table control blocks, less frequent memory accesses may be needed to keep up with the frame rate of packet transmission.
摘要翻译：公开了一种用于在网络处理器中实现多帧控制块的系统和方法。实施例包括用于减少长时间存储器访问到诸如DRAM之类的便宜的存储器的系统和方法。随着网络中的网络处理器接收数据包，网络处理器为每个数据包形成帧控制块。帧控制块包含指向存储分组数据的存储器位置的指针，并且因此与分组相关联。网络处理器将存储在控制存储器中的表控制块中的多个帧控制块相关联。每个表控制块包括指向表控制块链中的下一个表控制块的存储器位置的指针。由于帧控制块在表控制块中被存储和访问，因此可能需要较少频率的存储器访问以跟上分组传输的帧速率。

摘要： A method, system and computer program product for translating a type of service field of one protocol into multiple protocols. An ingress router in a DIFFerentiated SERVices network (Diffserv over MPLS network) may determine a type of quality of service, e.g., forward IP packet using best effort. A value referred to as a Per Hope Behavior (PHB) value may be generated based on the identified type of quality of service. The PHB value may be used to index into a table comprising a row of entries with different quality of service values, e.g., DSCP value, EXP value, corresponding to a particular PHB value. Consequently, the PHB value may be used to perform a single memory access to determine the quality of service values for a plurality of protocols where the quality of service values corresponds to the identified type of quality of service.
摘要翻译：一种方法，系统和计算机程序产品，用于将一种协议的服务领域的类型转换为多种协议。 DIFFerentiated SERVices网络中的入侵路由器（MPLS网络上的Diffserv）可以使用最大的努力来确定服务质量的类型，例如转发IP分组。可以基于所识别的服务质量类型来生成被称为希望行为（PHB）值的值。 PHB值可以用于索引到包括具有不同服务质量值的条目行的表，例如对应于特定PHB值的DSCP值，EXP值。因此，PHB值可用于执行单个存储器访问以确定多个协议的服务质量值，其中服务质量值对应于所识别的服务质量类型。

摘要： A method, system and computer program product for routing packets. A network device, e.g., router, may comprise a switch fabric coupled to a plurality of blades where each blade may comprise one or more network processors coupled to one or more physical ports. The physical ports may be connected to another one or more network devices. A plurality of physical ports across one or more blades connected to the same network device may be logically mapped into a logical interface to that network device. By logically grouping a plurality of physical ports into a logical interface to a network device, a network processor may be able to transmit packets of data to that network device across multiple ports instead of one physical port.

摘要： A system and method in accordance with the present invention allows for an adapter to be utilized in a server environment that can accommodate both a 10 G and a 1 G source utilizing the same pins. This is accomplished through the use of a high speed serializer/deserializer (high speed serdes) which can accommodate both data sources. The high speed serdes allows for the use of a relatively low reference clock speed on the NIC to provide the proper clocking of the data sources and also allows for different modes to be set to accommodate the different data sources. Finally the system allows for the adapter to use the same pins for multiple data sources.
摘要翻译：根据本发明的系统和方法允许在可以使用相同引脚容纳10G和1G源的服务器环境中使用适配器。这是通过使用可以容纳两个数据源的高速串行器/解串器（高速serdes）来实现的。高速serdes允许在NIC上使用相对较低的参考时钟速度来提供数据源的适当时钟，并且还允许设置不同的模式以适应不同的数据源。最后，该系统允许适配器为多个数据源使用相同的引脚。

摘要： A system and method for computing a blind checksum includes a host Ethernet adapter (HEA) with a system for receiving a packet. The system determines whether or not the packet is in Internet protocol version four (IPv4). If the packet is not in IPv4, the system computes the checksum of the packet. If the packet is in IPv4, the system determines whether the packet is in transmission control protocol (TCP) or user datagram protocol (UDP). If the packet is not in either of TCP or UDP the system attaches a pseudo-header to the packet and computes the checksum of the packet based on the pseudo-header and the IPv4 standard.

摘要： A system and method for parsing, filtering, and computing the checksum in a host Ethernet adapter (HEA) that is coupled to a host. The method includes receiving a part of a frame, wherein a plurality of parts of a frame constitute a entire frame. Next, parse the part of a frame before receiving the entire frame. The HEA computes a checksum of the part of a frame. The HEA filters the part of a frame based on a logical, port-specific policy and transmits the checksum to the host.
