Memory Access Timestamp

Fields

prev_high: T

The previous timestamp’s high 24 bits that this memory access is being read from.

prev_low: T

The previous timestamp’s low 24 bits that this memory access is being read from.

compare_low: T

This will be true if the top 24 bits do not match.

diff_low_limb: T

The following columns are decomposed limbs for the difference between the current access’s timestamp and the previous access’s timestamp. Note the actual value of the timestamp is either the accesses’ high or low 24 bits depending on the value of compare_low.

This column is the least significant 16 bit limb of the difference.

diff_high_limb: T

This column is the most significant 8 bit limb of the difference.
