Abstract
A mask packet is provided with bits in a ONE state for all predictable bit positions and with a ZERO state for all unpredictable ones. All predictable bit positions of the new data packet are brought into a ZERO state if an actual bit state matches the predicted bit state and into a ONE state if the actual bit state does not. A processed packet is generated by applying an AND operation between the new data packet and the mask packet to change all unpredictable bits to a ZERO state. A series of counters is provided by calculating the number of bits in the processed packet between the first bit and the first bit with a state ONE; and between the following bits with a state ONE and between the last bit with a state ONE and the last bit in the processed packet. The counters are stored or transmitted.
