Abstract: Method and system for processing packets received from a network is provided. The system includes an adapter having a processing module that separates a header of a network packet from data, forwards the header to a host system and stores data associated with the network packet in a memory device of the network adapter. The host system processes the header and determines a destination for the network packet data. The method includes determining header boundary in a network packet, wherein an adapter coupled to a host system determines the header boundary; ending header information to the host system; and storing data associated with the network packet in a memory device of the adapter.

Abstract: A central processor for use in a data processing system that is adapted for processing sequences of characters. Information identifying a string of characters to be examined, including the memory location for the first character in the sequence and the total number of characters in the sequence, is placed in working registers of the central processor. Other working registers in the central processor receive information corresponding to a predetermined characteristic, which may be a specific character or information identifying another character string. One of several character string instructions then can be processed. In response to a typical character string instructuion, the central processor retrieves each character from the memory and compares it with the predetermined characteristic. Processing continues until either the predetermined characteristic is detected or all the characters in the character string are examined.

Abstract: A central processor for use in a data processing system that is adapted for processing sequences of characters. Information identifying a string of characters to be examined, including an initial memory location of the first character in the sequence and the total number of characters in the sequence, is placed in working registers of the central processor. Other working registers in the central processor receive information corresponding to a predetermined characteristic, which may be a specific character or information identifying another character string. One of several character string instructions then can be processed. In response to a typical character string instruction, the central processor performs the function defined by the instruction in an iterative fashion as the central processor retrieves successive characters from a memory. During each iteration the central processor tests to determine whether any interruption conditions exist.
