  • Patent number: 9916145
    Abstract: Apparatus, systems, and methods for a compiler are described. One such compiler generates machine code corresponding to a set of elements including a general purpose element and a special purpose element. The compiler identifies a portion in an arrangement of relationally connected operators that corresponds to a special purpose element. The compiler also determines whether the portion meets a condition to be mapped to the special purpose element. The compiler also converts the arrangement into an automaton comprising a plurality of states, wherein the portion is converted using a special purpose state that corresponds to the special purpose element if the portion meets the condition. The compiler also converts the automaton into machine code. Additional apparatus, systems, and methods are disclosed.

  • Patent number: 9535861
    Abstract: A device includes a routing buffer. The routing buffer includes a first port configured to receive a signal relating to an analysis of at least a portion of a data stream. The routing buffer also includes a second port configured to selectively provide the signal to a first routing line of a block of a state machine at a first time. The routing buffer further includes a third port configured to selectively provide the signal to a second routing line of the block of the state machine at the first time.

  • Patent number: 9509312
    Abstract: Disclosed are methods and devices, among which is a device that includes a finite state machine lattice. The lattice may includes a programmable Boolean logic cell that may be programmed to perform various logic functions on a data stream. The programmability includes an inversion of a first input to the Boolean logic cell, an inversion of a last output of the Boolean logic cell, and a selection of an AND gate or an OR gate as a final output of the Boolean logic cell. The Boolean logic cell also includes end of data circuitry configured to cause the Boolean logic cell to only output after an end of data signifying the end of a data stream is received at the Boolean logic cell.

  • Patent number: 9298437
    Abstract: Apparatus, systems, and methods for a compiler are disclosed. One such compiler parses a human readable expression into a syntax tree and converts the syntax tree into an automaton having in-transitions and out-transitions. Converting can include unrolling the quantification as a function of in-degree limitations wherein in-degree limitations includes a limit on the number of transitions into a state of the automaton. The compiler can also convert the automaton into an image for programming a parallel machine, and publishes the image. Additional apparatus, systems, and methods are disclosed.
