摘要： Methods are provided for compactly representing behaviors of a processor of packets. A declarative description of the processor is input. The declarative description specifies rules for manipulating the packets. A dependency graph is generated from the declarative description. The dependency graph specifies each rule that depends upon another one or more of the rules. The declarative description and the dependency graph are transformed into a Petri net representing the behaviors of the processor. The Petri net includes respective transitions for the rules and places for enabling the transitions to fire. A specification of the Petri net is output. The Petri net represents the behaviors of the processor.

摘要： A programmable integrated circuit performs an initial partial configuration of the programmable integrated circuit in response to receiving an activation signal. In this way, the programmable integrated circuit enables an initial functionality of the programmable integrated circuit. The programmable integrated circuit then performs a subsequent partial configuration of the programmable integrated circuit for enabling additional functionality of the programmable integrated circuit. In some embodiments, the programmable integrated circuit receives an input signal indicating a stimulus in an environment of the programmable integrated circuit and determines based on the input signal whether to perform the subsequent partial configuration of the programmable integrated circuit or generate a power down signal for powering down the programmable integrated circuit without performing the subsequent partial configuration. In some embodiments, the programmable integrated circuit performs a sequence of partial subsequent configurations for enabling a sequence of additional functionalities of the programmable integrated circuit.
