NRZI processing methods and devices to correct for sync detection failures

摘要

New and useful methods and systems for detecting sync signals/patterns in streams of data are disclosed. For example, in an embodiment system for processing data includes a first module having dedicated processing circuitry configured to detect a sync signal embedded in a received stream of data and to produce an output stream of data, and second module that includes a firmware-controlled processor configured to correct sufficient errors within the received stream of data so as to allow the first module to detect the sync signal on a condition when the first module by itself is incapable of resolving the sync signal caused by the errors in the received stream of data.

主权项

1. A system for processing data, comprising:
a hardware module configured to detect a sync signal embedded in an input stream of data passed from a firmware-based module to the hardware module unchanged and to produce an output stream of data; and the firmware-based module configured to correct errors in the input stream of data independently from the hardware module when the hardware module is incapable of correctly detecting the sync signal to the errors in the input stream of data.
