METHODS AND SYSTEMS FOR USING STATE VECTOR DATA IN A STATE MACHINE ENGINE

摘要

A state machine engine includes a state vector system. The state vector system includes an input buffer configured to receive state vector data from a restore buffer and to provide state vector data to a state machine lattice. The state vector system also includes an output buffer configured to receive state vector data from the state machine lattice and to provide state vector data to a save buffer.

1. A system, comprising
a host device comprising a processor and a memory coupled to the processor; and a state machine engine coupled to the host device, wherein the state machine engine comprises:
a state machine lattice; anda state vector system coupled to the state machine lattice, wherein the state vector system comprises:
an input buffer configured to receive state vector data from a restore buffer of the state machine engine and to provide state vector data to the state machine lattice to initialize or restore a state of the state machine lattice, wherein the state vector data includes a state vector as an indication of a state of all or certain configurable elements of the state machine lattice at a given moment as an indication of a particular state of the state machine lattice; andan output buffer configured to receive state vector data from the state machine lattice and to provide state vector data to a save buffer of the state machine engine as save map data.
