Read-only memory reduction by segmentation

Techniques are introduced to reduce r.o.m. wordlength in microprogrammed digital computers, whilst microcommands are stored in a completely decoded form, by means of appropriate segmentation of the r.o.m. Some comparisons with conventional methods for r.o.m. reduction, involving partial coding of microcommands, are also carried out. © 1970, The Institution of Electrical Engineers. All rights reserved.
