发明名称 Method and apparatus for implementing frame header alterations
摘要 A method and apparatus are provided for implementing frame header alterations in a network processor. A command decoder receives and decodes frame alteration commands and provides frame alignment commands and alteration instructions. A data aligner receives frame data and is coupled to the command decoder receiving the frame alignment commands. The data aligner includes an insert and delete unit that sequentially receives a predefined number of bytes of frame data, selectively latches data bytes of the received predefined number of bytes of frame data responsive to the frame alignment commands and sequentially provides an aligned frame data output of the predefined number of bytes. An alteration engine is coupled to the data aligner receiving the sequential aligned frame data output and is coupled to the command decoder receiving the alteration instructions. The alteration engine provides sequential altered frame data responsive to the received alteration instructions.
