Abstract

This article describes a system which is capable of reorganizing plural color planes, i.e., memory planes for a color display. That is, n planes each of which contains X bytes can be reorganized as n/2m planes each of which contains 2m X bytes, wherein n and m are integers and (Image Omitted) The figure shows the reorganization system comprising color planes 1, 2, ... n. These planes produce outputs to respective parallel/ serial converters (PSCs) 111, 112, ... 11n which are, in turn, connected to AND gates 121, 122, ... 12n, respectively. These AND gates produce output signals C1, C2, ... Cn which are used to select one of the palette registers in a palette circuit 13. Each palette register contains color control data of p bits for controlling colors of image on a CRT color display 14. Data in the planes 1, 2, ...
