The Advanced “Jump-Counting” Skipfield Pattern

The Advanced “Jump-Counting” Skipfield Pattern This document describes a numeric pattern for indicating skippable items in data sequences and methods to adjust this pattern when the skippable status for an individual item changes. The pattern provides up to 525% faster iteration speeds (dependent on the ratio of skipped to unskipped items) than an equivalent boolean skipfield on a modern pipelined CPU. This is due to a lack of branching code, reduced number of skipfield reads and a reduced instruction count during iteration, when compared with the boolean pattern. This efficiency is accomplished without significantly impacting the duration taken to change an item’s skippable status. The pattern has significant application in generalized computer science but specifically in the implementation of data containers. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png The Computer Games Journal Springer Journals

Abstract

This document describes a numeric pattern for indicating skippable items in data sequences and methods to adjust this pattern when the skippable status for an individual item changes. The pattern provides up to 525% faster iteration speeds (dependent on the ratio of skipped to unskipped items) than an equivalent boolean skipfield on a modern pipelined CPU. This is due to a lack of branching code, reduced number of skipfield reads and a reduced instruction count during iteration, when compared with the boolean pattern. This efficiency is accomplished without significantly impacting the duration taken to change an item’s skippable status. The pattern has significant application in generalized computer science but specifically in the implementation of data containers.
