Microprogramming for Data Acquisition and Control

The paper describes a different approach to the control of experimental apparatus in which control is performed by a microprogram controlling a very general register configuration and a single logical element. The basic concepts of microprogram control are described, including how program sequencing is accomplished and used to permit a variety of control capabilities including the generation of non-linear functions within a single system. A short discussion of presently available components will provide some perspective as to the performance levels that may be achieved and system availability. As an example, a possible microprogram controller for the PEPR film scanning system will be described in some detail and its potential performance outlined.
