摘要： A hardware apparatus for receiving a packet for a TCP offload engine (TOE), and receiving system and method using the same are provided. Specifically, information required to protocol processing by a processor is stored in the internal queue included in the packet receiving hardware. Data to be stored in a host memory is transmitted to the host memory after the data is stored in an external memory and protocol processing is performed by the processor. With these techniques, it is possible that a processor can operate asynchronously with a receiving time of a practical packet and it is possible to reduce an overhead that processor deals with unnecessary information
