Abstract:
1. An apparatus for depacketizing and aligning input data having a packetized format, comprising: an input memory for receiving, storing, and output of input data, and for outputting of units of a payload of a data packet of the input data; a data input interface through which the input data is transferred to the input memory, said input data interface configured to perform hand shaking with a packetized data source of said input data; data processing means for receiving the outputted input data from the input memory and detecting, identifying and determining payload size of the data packet and generating a payload size signal indicative of the size of the payload, and for separately receiving and effecting data processing of the payload; a word formatter for receiving said units of said payload outputted from the input memory, gathering and aligning said units to form data words, and for outputting said data words; a payload counter for controlling the input memory in accordance with the payload size signal and configured to cause the payload units to be outputted from the input memory to the word formatter; and an input buffer for receiving said data words from the word formatter and storing them, and for transferring the data words to the data processing means, to effect separate receiving of said payloads; and processing using the received said data words.
