Abstract

Simplified addressing hardware is used to merge or separate groups of contiguous data segments when the lengths of such segments are binary powers. Addressing to combine segments of data (Fig. 1) from Data Segment Area 11 in RAM (random-access memory) 10 with segments of data from Data Segment Area 12 in RAM 10 takes advantage of properties of binary powers, allowing addressing to be implemented with a single incrementing address register. (Image Omitted) Three requirements are: 1. The length of the data segments must be a binary power. 2. The starting location of the Data Segment Areas must be divisible without remainder by the length of the smaller segment. 3.
