摘要： The present invention relates to a general-purpose programmable packet-processing platform for accelerating network infrastructure applications which have been structured so as to separate the stages of classification and action. Network packet classification, execution of actions upon those packets, management of buffer flow, encryption services, and management of Network Interface Controllers are accelerated through the use of a multiplicity of specialized modules. A language interface is defined for specifying both stateless and stateful classification of packets and to associate actions with classification results in order to efficiently utilize these specialized modules.

摘要： The present application describes a compiler of a network packet classification programming language that generates code for processors such as an application processor and a processing engine. The programming language includes a variety of instructions including an instruction to declare a network protocol and an instruction to specify a rule and at least one action to perform if the rule applies. A processor executing instructions generated by the compiler assigns values based on instructions to declare a network protocol and applies the rule instructions to received packets. The programming language may also include other instructions such as an instruction to search a set of values and identify whether an encapsulated packet header is present in a packet.

摘要： A master bus interconnecting multiple masters is coupled via any number of intervening buses to a slave bus interconnecting multiple slaves and masters. A lock arbiter signal is passed to each successive bus-to-bus interface concurrent with an instruction issued by a master accessing a slave on a remote bus. Address, control, data, and lock arbiter signals are buffered in successive intervening bus-to-bus interfaces including the bus-to-bus interface to the slave bus. The lock arbiter signal when received by the slave bus-to-bus interface will set a lock arbiter register within bus slave bus-to-bus interface. Setting the lock arbiter register once a target slave has been accessed prevents any other master operating on the remote bus from using the remote bus or connecting to the remote bus-to-bus interface. Indivisible sequences of bus operations targeted for the target slave may be confined to the bus to which the target slave is coupled although intervening buses and bus-to-bus interfaces may be disconnected and reassigned pending completion of the indivisible sequence.
