Abstract: Systems and methods are provided for encoding forwarded error for data bus width conversion. Input data and input forwarded error information are received. System input parity information is computed based on the input data and the input forwarded error information. Output data based on the input data and system output parity information based on the system input parity information are provided, and it is determined whether to indicate a forwarded error output based on the output data and the system output parity information.

Abstract: Systems, methods, and devices for selecting modes of operation include, in at least one aspect, a method including: selecting a first mode associated with digital-analog conversion; determining whether a second mode associated with digital-analog conversion is available; if the second mode is available, evaluating one or more switching parameters associated with the second mode; switching from the first mode to the second mode if the one or more evaluated switching parameters satisfy one or more predetermined criteria; analyzing one or more performance parameters after switching from the first mode to the second mode; and setting the second mode as a default mode of operation if the one or more analyzed performance parameters are satisfactory.
