A frame analyzer component and a memory management unit process frames received over cable television lines. The frame analyzer component may receive frames that were transmitted over the cable television lines and that were processed by a digital signal processor. The frame analyzer component checks incoming frames or frame fragments for consistency and errors. Results from the frame analyzer component relative to frame fragments may be stored in a context memory. When a later fragment of the frame arrives, the previous context of the frame can be restored and used to continue processing the frame. The memory management unit stores the frames and frame fragments in separate memory management tables.
