Abstract: A variable write back indicator control is provided to control the amount of data to be re- transmitted when a packet error occurs. A hardware controller obtains an indication that an acknowledge rate or an amount of set write back indicators of a data frame is to be adjusted. The indication is based on an error rate of data transmission over a communication bus. Based on obtaining the indication that the amount of set write back indicators is to be adjusted, one or more write back indicators are adjusted.

Abstract: A re-characterization process is provided that adjusts one or more operating parameters of a processor to improve the health (e.g., reduce errors) of the processor. The parameters include voltage and/or clock frequency, as examples. The processor can be an inactive or active processor for which the re-characterization process is performed. It is performed, in one instance, by a hardware controller in real-time.
