    摘要： A communication processor of a class, such as an Internet tuner, provides such desirable features (FIG. 2) as LAN support, an SPI interface (128), a dedicated port (56), and ADPCM (22) for audio applications. The invention provides a low-cost, low-power, easily manufactured, small form-actor network access module which has a low memory demand and provides a highly efficient protocol decode. The invention comprises a hardware-integrated system that both decodes multiple network protocols in a streaming manner concurrently and processes packet data in one pass, thereby reducing system memory and form factor requirements, while also eliminating software CPU overhead.

    摘要： A gigabit Ethernet adapter provides a provides a low-cost, low-power, easily manufacturable, small form-factor network access module which has a low memory demand and provides a highly efficient protocol decode. The invention comprises a hardware-integrated system that both decodes multiple network protocols in a byte-streaming manner concurrently and processes packet data in one pass, thereby reducing system memory and form factor requirements, while also eliminating software CPU overhead. A preferred embodiment of the invention comprises a plurality of protocol state machines that decode network protocols such as TCP, IP, User Datagram Protocol (UDP), PPP, Raw Socket, RARP, ICMP, IGMP, iSCSI, RDMA, and FCIP concurrently as each byte is received. Each protocol handler parses, interprets, and strips header information immediately from the packet, requiring no intermediate memory. The invention provides an Internet tuner core, peripherals, and external interfaces. A network stack processes, generates and receives network packets. An internal programmable processor controls the network stack and handles any other types of ICMP packets, IGMP packets, or packets corresponding to other protocols not supported directly by dedicated hardware. A virtual memory manager is implemented in optimized, hardwired logic. The virtual memory manager allows the use of a virtual number of network connections which is limited only by the amount of internal and external memory available.

    摘要： An Internet small computer system interface (iSCSI) system, method and associated data structure are provided for receiving data in protocol data units. After a protocol data unit is received, a data list is identified that describes how the data contained in the protocol data unit is to be stored (i.e. placed, saved, etc.) in memory (i.e. application memory). Further stored is a state of the data list. To this end, the state of the data list is used in conjunction with the storage of data from a subsequent protocol data unit.
