VARIABLE ACKNOWLEDGE RATE TO REDUCE BUS CONTENTION IN PRESENCE OF COMMUNICATION ERRORS

摘要

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.
