Abstract: Hardware internet packet processing device for network security constructed in such a manner that packet data is packet processed by hardware without a receiving memory or MCU and interruption of internet packets for network security is implemented by hardware construction.

Abstract: The present invention relates to a communication apparatus with a high-speed data processing function for an embedded system, and an apparatus thereof. A MAC process communication apparatus comprises hardware TCP/IP processing and socket decision means. Upon transmission of data, if data to be transmitted are previously set hardware processing data, an application interface unit transfers the data directly to the hardware TCP/IP processing means without through the OS and the hardware TCP/IP processing means process a TCP/IP protocol of the transmission data, and if the data to be transmitted are not the hardware processing data, but are general data, the OS processes the TCP/IP protocol in a software manner.
