Abstract

A content searching chip and system based on a peripheral component interconnect (PCI) bus. The content searching chip includes a peripheral component interconnect interface module, a protocol conversion module, and a content storage module. The content storage module is connected to the protocol conversion module using an instruction bus and a data bus. The peripheral component interconnect interface module acquires a first processing layer data packet using the peripheral component interconnect bus; the protocol conversion module acquires the first processing layer data packet from a parallel bus provided between the protocol conversion module and the peripheral component interconnect interface module, parses and converts the first processing layer data packet to an operation request and data; the content storage module stores content, performs an operation according to the operation request, and returns operation response data; the instruction bus transmits the operation request, and the data bus transmits the data.
