Patent ID: 6954891

Claim:
A method for delineating a frame, comprising the steps of: (A) receiving said frame comprising (i) a length field storing a length value for a combined length consisting of a payload field and a payload error detection field, (ii) a length error detection field storing a length error detection value for said length value, (iii) said payload field storing a payload data and (iv) said payload error detection field storing a payload error detection data for said payload data; (B) performing an error detection on said length value based upon said length error detection value; and (C) retrieving said payload data and said payload error detection data from said frame based upon said length value and in response to passing said error detection on said length value, wherein said retrieving step comprises the sub-steps of: (i) generating by counting bytes in the frame a select signal based upon both said length value and a predetermined value; and (ii) generating by multiplexing (i) a first signal carrying said payload data and (i) a second signal carrying said payload error detection data based on said select signal.
