摘要:
A logic circuit is configured to calculate a sliding sum of absolute differences of a plurality of numbers from a plurality of members respectively selected successively from all members of a sequence of numbers. The logic circuit reduces an amount of logic that is required to perform the sum of absolute differences, and thereby saves resources and latency.
