The instruction table specifies a regular expression for application to a data stream. The system includes a regular expression engine (engine) that processes the data stream using the instruction table. The engine includes a decoder circuit that determines validity of active states output from the multi-port RAM and a plurality of priority FIFO memories (PFIFOs) operating concurrently. Each PFIFO can initiate a read from a different port of the multi-port RAM. Each PFIFO can track a plurality of active paths for the regular expression and a priority of each active path by, at least in part, storing entries corresponding to active states in each respective PFIFO in decreasing priority order. The engine includes switching circuitry that selectively routes the active states from the decoder circuit to the plurality of PFIFOs according to the priority order."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"High-throughput regular expression processing with path priorities using an integrated circuit","description":"A system includes a multi-port RAM configured to store an instruction table.
