Abstract:
An apparatus can include a first state machine engine configured to receive a first portion of a data stream from a processor and a second state machine engine configured to receive a second portion of the data stream from the processor. The apparatus includes a buffer interface configured to enable data transfer between the first and second state machine engines. The buffer interface includes an interface data bus coupled to the first and second state machine engines. The buffer interface is configured to provide data between the first and second state machine engines.
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.
Abstract:
Apparatuses and methods are provided for reducing power consumption in a pattern-recognition processor. A power control circuit may be coupled to a block of programmed state machines to enable selective activation and deactivation of the block during a pattern search. The block may be deactivated if the pattern search is no longer active in that block and activated when needed by the pattern search. Additionally, the block may be deactivated based on an identifier of the data stream being searched. Excess blocks not used for any programmed state machines may be disabled such that they are not refreshed during a memory cycle.

Abstract:
Multi-level hierarchical routing matrices for pattern-recognition processors are provided. One such routing matrix may include one or more programmable and/or non-programmable connections in and between levels of the matrix. The connections may couple routing lines to feature cells, groups, rows, blocks, or any other arrangement of components of the pattern-recognition pr
Abstract:
The Automata Processor Workbench (AP Workbench) is an application for creating and editing designs of AP networks (e.g., one or more portions of the state machine engine, one or more portions of the FSM lattice, or the like) based on, for example, an Automata Network Markup Language (ANML). For instance, the application may include a tangible, non-transitory computer-readable medium configured to store instructions executable by a processor of an electronic device, wherein the instructions include instructions to represent an automata network as a graph.
